How to Run the Marathon Des Sables, Part 2: Food

So, you want to run the Marathon Des Sables, a seven-day stage race of self-sufficiency in Morocco’s Sahara Desert! Congratulations and welcome to life-changing experience. Between the resources you put into the trip itself and your preparation for it, the Marathon Des Sables (MDS) requires loads of time and money. I have run the MDS six times, so clearly I think that it’s all worth it.

You know that phrase used in construction, ‘Measure twice, cut once?’ As in, prepare ahead of time and make fewer mistakes in the heat of the moment? I have found the same to be true when it comes to prepping for the MDS. The more committed you are to the pre-race and during-race MDS experience, the better it will be. By ‘better,’ I mean that you will feel physically better and have more fun. This goes for preparing your kit, food, training, and logistics. I’ve made mistakes and seen others make them too. Usually, our mistakes could have been prevented with preparation beforehand, though, and that’s what this article is about!

This article is part two of a three-article series where we offer detailed information on how to prepare for and run the MDS. The first article is focused on preparing your kit, which refers to all of the gear you carry and wear during the race. Part three offers recommendations on training and the other logistics that go into preparing for the MDS.

While we write specifically about the MDS experience, a lot of what you’ll find in this article series can be applied in theory to other expedition-length, self-sufficiency stage races, too.

In this article, we begin by talking about the basic principles of preparing your MDS food list, and then dive into detailed recommendations as well as my own 2019 MDS food list.

Marathon des Sables Food Principles

When we talk about MDS food, we mean all the food you’ll eat during the self-sufficiency part of the race. This includes what you eat at camp before and after each racing stage, as well as what you eat while running. Here are the six basic principles I think best guide choosing MDS food:

  1. Follow the race rules.
  2. A combination of calorically dense, dehydrated, and carbohydrate-rich foods is queen/king.
  3. Pre-test everything.
  4. Bring (a bit) more than 2,000 kilocalories per day.
  5. You are a study of one.
  6. Choose foods that don’t require a pot, cup, stove, or fuel (besides the sun).

Follow the race rules.

As you’ll see mentioned a number of times in this article series, there are a lot of rules at the MDS! Thus it’s no surprise that there are several rules about the food we eat at the race. The MDS rules on food attend to three specific issues: a minimum required calorie count, the inclusion of a nutrition label for all food, and no gas stoves allowed at the race.

First, that minimum calorie count. The race organization mandates you to carry a minimum of 14,000 kilocalories (kcals) of food, or a minimum of 2,000 kcals per day. The organization further requires you to maintain a minimum calorie count on the morning of each stage, explained in a chart in the race rules. This includes still having 2,000 kcals when you wake up on the morning of the seventh day/the sixth (charity) stage.

Then, the race rules state that any food you bring that’s out of its original packaging must have the product’s nutrition label. Many people repackage their food into lighter bags and vessels, and if you do be sure to include the nutrition label in your new packaging.

Finally, gas stoves aren’t permitted at the MDS. Some people purchase Esbit fuel tablets and stoves at the MDS store located at the starting-line bivouac, which are allowed at the race. Other people collect and use the very small amount of wood and grass located in the natural environment to make cooking fires. Still others use the radiant heat of the sun to cook their food. And some people eat food that needs no cooking.

A combination of calorically dense, dehydrated, and carbohydrate-rich foods is queen/king.

Throughout this article series, I emphasize the importance of making your MDS pack and everything in it as light as possible. After all, you will lug all of it an estimated 250 kilometers (155 miles) for a week across sand dunes, over mountains, and through oppressive heat. This, of course, includes your food. Your journey to a lightweight food list is founded in choosing foods with decent caloric density and foods that don’t naturally contain much water or that have been dehydrated.

Let us first learn about caloric density, or the amount of energy per unit of weight that food has. In this article, we use kilocalories (kcals) as our energy unit and grams (g) as our weight unit. Foods with high caloric densities contain a lot of calories in a small amount of weight, while low-caloric-density foods don’t. As examples, olive oil is an extremely high-caloric-density food, containing 8.85 kcals/g, while carrots are very low, containing 0.4 kcals/g.

Now, dehydrated foods. As you will come to know very intimately during MDS when you are running with a lot of drinking water between checkpoints, water is heavy! One liter of water weighs one kilogram. Most food contains some water, and some foods contain a lot of it. On the other hand, some food naturally contains very little water, and a lot of food can be dehydrated. Take potatoes, which are made up of 80% water and are, as we all know, quite heavy. If you dehydrate a potato and leave its solid parts, you retain the nutritional value of the potato without having to lug its water around. Many dehydrated foods can be rehydrated just by adding water and sometimes a little heat.

All of this said, if you pack the most calorically dense and water-less foods that exist for MDS, you will end up with foods that you not only may not enjoy but also foods containing an incorrect ratio of macronutrients for your needs as an endurance runner. So, while you should endeavor to choose foods with these qualities, you must also consider what nutrients your body needs for a week of endurance running. That answer, for almost everyone out there, is a good deal of carbohydrates. Carbohydrate is the primary macronutrient that the human body uses as endurance-running fuel and in the basic metabolic processes of life. A significant amount of protein is needed as well, especially to help the body rebuild muscle after running. Fat is the third macronutrient that we need to keep the body humming along. At the MDS, a majority of your food should be carbohydrates, while the rest is split between protein and fat. My ratio of carbohydrates to protein to fat is skewed more toward carbohydrates at MDS than during a typical day at home. (This article doesn’t address the nutritional needs of fat-adapted endurance runners at the MDS.)

Pre-test everything.

I brought a certain kind of bar to my first MDS in 2009. At the time, I used these bars for hiking, backpacking, and trail running in normal conditions. But I never tested them in the heat expected at MDS. In fact, I never even thought about doing this. Turns out, I couldn’t eat these bars in the heat, whether I was running or simply sitting around the MDS bivouac. I had 10 of them, what amounted to about 2,500 kcals of my weekly food ration, that were useless to me because I didn’t test them ahead of time in MDS conditions.

Another general anecdote, a mistake I see MDS runners make. Many runners use dehydrated backpacking or similar meals because they are very light, and this is an excellent plan. However, some people have never eaten dehydrated food at all, while others haven’t tested their particular meals in MDS conditions. Some runners end up at MDS with food that their stomachs or taste buds don’t enjoy, and are stuck.

Don’t make the same mistake I and other people have! Pre-test all of your food in the expected environmental conditions. This means, test your running food while training in heat, and test your other food in hot, dry conditions. Most of us don’t live in Sahara Desert-like environments, but its conditions can be replicated in saunas, by wearing a lot of clothes outside, or by putting a heater in a bathroom or closet.

In my opinion, testing your food ahead of time comes down to testing it against three parts of your body:

  • Your taste buds – The food needs to taste good in MDS conditions.
  • Your gastrointestinal tract – Does the food digest easily and comfortably, including all the way through to your bowel movement? Does the food make you feel sated (enough) when eaten after a big training day?
  • Your brain – We all know that food affects our psychology, so choose foods that make you feel good. For instance, I have a few foods that I would call my ‘comfort foods,’ foods that I just love to eat. One of these is mashed potatoes, and because of this, I eat a lot of them at MDS.

Bring (a bit) more than 2,000 kilocalories per day.

As described before, the race requires you to bring 2,000 kcals of food per day. If you have any inkling about the calorie requirements the human body needs to stay alive for a day, plus the calorie requirements of endurance running, then you know that this isn’t even close to the amount of calories you’ll expend in a day at the MDS. At MDS you’ll lose body mass in the form of fat and muscle. Muscle loss can lead to decreased performance, and a large-enough caloric deficit for a week has a number of other poor health outcomes. While some weight loss is expected, we want to minimize the performance and health dings that result from it.

On the opposite side, bringing too much food leaves you with a heavy pack, which requires a lot of energy to carry. Bringing too much food will cause you to burn more energy carrying it than you will get out of ingesting it.

What is the correct amount of food for MDS then? This number is different for everyone, and it varies based upon what kind of runner you are and the speed you expect to travel during the race. Generally speaking, smaller people with a low muscle mass expend a smaller amount of energy in the body’s basic metabolic functions and while running, as compared to larger people with higher muscle mass. MDS participants who are able to maintain the running motion for the majority of the race will burn a higher proportion of carbohydrates, and participants who walk the majority of MDS will burn a higher proportion of fats. While the vast majority of human bodies contain enough stored fat to fuel a week of walking the MDS, no human body contains enough carbohydrates. While all of us need to feed ourselves an adequate amount of carbohydrates, those participants who are running most of the race and therefore burning carbohydrates may need to carry and ingest more carbohydrates than participants who are walking most of the race.

You are a study of one.

I mention this principle pretty much every time I talk about the MDS; you are a study of one when it comes to every aspect of your preparations for this event. When it comes to food, your food is your food, my food is my food, and Beth’s food is Beth’s food. What ends up on your food list should be the result of the pre-testing you do and not what your friend is bringing, what you read about in this article, or what you saw in a MDS Facebook group. What you learn from these resources is so important because it shows you what options are available to you, but what is even more important is that every item on your list passes your own pre-testing.

Choose foods that don’t require a pot, cup, stove, or fuel (besides the sun).

I’ll take some heat for this principle, but I stand behind it! It is a fact that you can create a MDS food list full of foods which contain adequate nutrition and are a true pleasure to eat, and that don’t require a pot, cup, stove, or fuel to cook and eat. I would thus argue that carrying a pot, cup, stove, and/or fuel is wasted weight. Instead, why not replace the saved weight with more food? I know, you like your coffee hot and the process of cooking is enjoyable for you. Me, too, but that’s at home when the weight of what you eat and cook with isn’t in issue! There are many ways to make your MDS eating enjoyable without weighing you down unnecessarily. Give this concept a chance.

My Marathon des Sables Food List

I created a public Google Sheet containing my 2019 MDS food list. I’ve also embedded it in its entirety at the close of this article. Through the rest of this article, I also include screenshots of each major kind of food.

Magda Boulet and Roxanne Vogel, who work for GU Energy Labs, and I worked together to develop my 2019 MDS food list. Magda ran and won the 2018 MDS, and Magda and Roxanne developed her successful 2018 food plan. I had run the MDS five times prior to this year and I additionally have a lot of multi-day backcountry travel experience, so I had a good idea of what foods and quantities work for me. Additionally, I use a lot of GU Energy Labs products in my daily run training and racing. So, the three of us worked together to create my 2019 food list. The process was really fun, and I’m grateful for their expertise and insight. I was 100% pleased with my 2019 MDS food list.

In the rest of this article, I’ll outline my 2019 MDS food list, why we chose the foods we did, and how they worked out for me this year.


The below graphic shows what I ate for breakfast most days at MDS:

At first glance, you’ll see that my breakfast fulfills the principle of using calorically dense, dehydrated, and carbohydrate-abundant foods at MDS. Roxanne Vogel created two flavors of homemade overnight oats, vanilla and apple, so that I could alternate flavors from breakfast to breakfast. I also brought several different kinds of Justin’s Nut Butter to vary flavors. I used the Rapid Fire Coffee Mix for a couple reasons. First, at home I drink coffee laden with coconut oil and this coffee mix contains that. Second, I tested a number of cold instant coffee/coconut-oil powder/flavor combinations, and this coffee mix tastes good and has a pleasing consistency while cold.

All of these foods can additionally be eaten without a pot, cup, stove, or fuel. All I needed was an ultralight eating utensil and the ultralight plastic bags I packaged the oats and coffee into before starting the race. Before going to sleep each night, I poured my dry-oats mix and some water into one of the 1.5-liter plastic bottles the race organization distributes water in to let the oats soak. (Not to mention that these water bottles can be sealed tight and thus prevent spilling due to sandstorms and whatever else might happen.) In the morning, I used the knife in my required kit to cut the top off the water bottle and ate out of the bottom of the bottle like it was a bowl. In the morning, I did the same thing with my coffee mix, pouring it into another water bottle, adding some water, shaking, and enjoying.

This breakfast, which has a little over 600 kcals, has a macronutrient profile of about 64 grams of carbohydrates, 24 grams of protein, and 26 grams of fat. While this profile is a little off kilter on the recommended carbohydrate to protein to fat ratio for pre-long-run fueling/MDS, it’s roughly the same macronutrient profile as my breakfasts at home where I front load fat consumption in the morning.

Post-Run Recovery and Snacks

The below graphic shows what I consumed immediately after finishing almost each MDS running stage:

In 180 kcals of GU Energy Labs Roctane Protein Recovery Mix, you get about 24 grams of carbohydrates and 16 grams of protein, which is an appropriate profile for endurance-running recovery–at least in the calorie-restricted MDS. Also, the chocolate-smoothie flavor is just delicious for me, and was a treat to drink even in very hot conditions immediately after running.

Finally, this recovery drink can be consumed without a special cup or pot. I packaged the powder into ultralight plastic bags. Upon finishing each stage, I poured the powder into one of the water bottles given to us by the race organization, added the appropriate amount of water, shook, and sipped.

The below graphic is one day’s example of my afternoon snacks at MDS:

These are the foods I ate in between finishing each stage of running around midday and ‘dinner time’ later in the afternoon/early evening. Here again we focus on foods that are a balance of being calorically dense; have little water; contain a decent macronutrient profile for me at MDS; require no pot, cup, stove, or fuel to cook or enjoy; and are a pleasure for me to eat.

An interesting backstory here: historically at MDS, I’ve struggled to eat foods that are sweet when I am not running. In fact, I’ve craved savory foods like nuts and dried plantains. (I’ve never had a problem with sweet running food at MDS, though.) When Magda Boulet and Roxanne Vogel encouraged me to consider eating GU Energy Labs Stroopwafels as non-running snacks, I voiced this concern. Magda said that perhaps my desire for savory foods was a result of electrolyte imbalance and my body actually craving the sodium that’s present in the foods I chose. She said that with good hydration and electrolyte balance, I might have no problem eating the sweeter Stroopwafels. I gave their theory a chance, testing them before the race in MDS-like conditions, and they were right. I loved my afternoon snacks at MDS!


The below graphic shows one of my MDS dinners:

As previously mentioned I love mashed potatoes, and I have for a long time relied upon and enjoyed various kinds of dehydrated mashed potatoes at the MDS and other backcountry travels. Knowing this, Roxanne Vogel developed four different flavors of homemade, dehydrated-mashed-potato-based meals. Each of them varied slightly in their weight and macronutrient profile based upon what she added to the base of dehydrated mashed potatoes. However, each offered close to 75 grams of carbohydrates, 25 grams of protein, and 16 to 20 grams of fat.

Ahead of time, I packaged each meal into a quart-size freezer bag. After I finished running each stage, I filled the bag with the appropriate amount of water, mixed the water and potatoes well, and sat the bag in the sun for a few hours. This cooked the potatoes, heating them and giving them a nice consistency. Freezer bags weigh a little bit more than the ultralight plastic bags in which I carried a lot of my food, but their durability is worth the extra few grams of weight because you cook your food in and eat out of them. I don’t want to lose food to a leak!

This cooking method can be used to rehydrate and cook a huge number of foods and is a perfect way for most MDS runners to prepare their dinners without needing to carry a pot, cup, stove, or fuel. The kind of MDS runner who is an exception to this rule are those who finish each stage around dark and don’t have access to the sun at camp for cooking. However, these runners can employ a tactic I use in some of my non-race backcountry travels for cooking my food on the move. That is, a couple hours before I want to eat, I pour water into my dehydrated-food bag, and then place that bag in an outside pocket of my pack so that it’s exposed to the sun and cooks while I am moving. Of course, you need to take care to protect your food, but I have used this methodology with much success, and MDS runners who finish stages late in the day can too.

Moving Food

The below graphic shows what I consumed while running Stage 5, the marathon-length stage, of MDS:

Here we arrive to what I think is the trickiest part of creating your MDS food list, choosing what you will consume during the stages themselves. Let me begin by saying that I am normally able to run the vast majority of MDS. Additionally, my years of endurance running at home have shown that I can digest between 250 and 300 kcals of mostly carbohydrate-based running fuel per hour, and that this leads to good energy levels for endurance running. At the calorie-restricted MDS, I plan for a minimum of 200 kcals/hour of carbohydrate-based running fuel. At home in the months leading up to MDS, I train with fewer than 250 kcals/hour on long runs, usually something in the 100 to 200 kcals/hour range, so that I can run with success on 200 kcals/hour at MDS.

You’ll see on my food list that the amount of food I packed for each day of running varied, and this was based upon how long I thought each stage would take me to run. MDS participants learn the length and layout of each stage during the long bus ride out to the starting-line bivouac, only two days before the race begins. As such, I bring with me to the starting-line bivouac plenty of running food, and then shift it into position once I see the layout and distance of each stage and can estimate how long each will take me to run.

Next, I consider the water element of running food, and how to minimize it as best as I am able. Running gels and chews have significant water weight, while powders do not. This is why I chose the GU Energy Labs Roctane Drink Mix for the majority of my running fuel as it comes in powder form. I incorporated GU Energy Labs Chews too because I have found that putting something slightly solid into my stomach during long runs keeps me from having hunger pangs. Additionally, I think it’s important for me to ingest multiple forms and flavors of fuel while running for so many hours in one week.

Of note, I did not repackage any of my moving food into ultralight plastic bags. While the original packaging of the drink mix was a bit heavier than I would like, I was nervous about accidentally ripping an ultralight bag while trying to quickly refill bottles while racing. In the end, I decided that the extra packaging weight was worth it in durability.

I can’t emphasize enough the ‘you are a study of one’ principle here. In my now six MDS runs, the food I consume while running has changed the most among everything on my MDS food list. My needs and palette have changed through time, and so does my food.

Other Details

At MDS, runners provide their own food starting on the morning of Stage 1 through the finish of Stage 6. You’ll see in my food list that I don’t have Stage 1’s breakfast listed. While that breakfast counts toward the minimum calorie requirements in the race rules, I don’t include it on my food list because I eat it before we run and because I bring well over 14,000 kcals and don’t need to include it to reach the required total. I ate the same breakfast before Stage 1 as the other days, with the addition of a fresh banana that I brought with me to the starting-line bivouac.

You’ll notice that, on Stage 6, I am carrying almost 1,400 kcals of powdered butter. The race rules mandate you to have 2,000 kcals of food left when you wake up on the morning of Stage 6. Of course, I didn’t eat the butter but carried it to fulfill the race requirements.

As seen on the food list, my total calorie count was 18,121 kcals and it weighed 4,532 grams.

    thank you, interesting.

    I assume the potato-based meals included something other than the potatoes, to get the fat and protein contents up ?
    Also, a somewhat delicate question, notice the nutrition label shows no fiber as such for these meals.. my son has to carry laxatives on backpacking trips, since the diet just doesn’t move him, so to speak.. do you need anything to stay regular or is the running enough ?

    1. Meghan Hicks

      Hi Doug k,

      Yep, that’s exactly it, via powdered cheese and sour cream, mostly, and perhaps a few other small ingredients.

      Indeed, this entire meal plan is very low on fiber! There are many reasons why I love and drink coffee wherever on earth I am when I wake up, and its morning ‘moving’ effect is one of them. ;-) I have not needed to use anything in addition to this to keep my lower-intestinal tract functioning well at MDS or in the backcountry otherwise.

      In all seriousness, I know of plenty of people who have constipation issues while on backcountry trips, stemming out of several potential causes including eating foods that are a lot different from what we eat at home/eating food with little fiber; mild dehydration via spending entire days outdoors, hiking, and carrying extra backpack weight; and the general increased physiological stress of backpacking/backcountry travel. Diet-wise, there are a lot of ways to get higher-fiber foods into the backcountry, if this is something that helps keep the GI tract happy, such as dehydrated fruit and beans, bars containing a decent amount of fiber, and nuts.

      1. Doug K

        thanks – I’m always fascinated by other people’s meal plans for long hikes or other endurance efforts ;-)

        thought of adding psyllium to the powdered meal, but as my wife pointed out, if insufficiently hydrated, the fiber might have the opposite effect to that intended..

        once did a relay run from Durban to Johannesburg, 610km between the twelve of us, a kilometer at a time..
        as I recall we ate not much real food, mostly a powdered meal substitute made for post-operative patients who couldn’t eat solids – a sort of slimfast type meal.

    Love this, thank you! No MDS for me, but I am heading to Moab 240 in October. This def. generates some ideas for myself. Any tips for the multi-day single stage nutrition plan, or things you found different about how your gut responded to your nutrition plan in this setting? I only have experience racing up to 30ish hours, what changes do you notice in your nutrition/what you tolerate/what works after 24-48 hours of running? I am hoping to be “running” (a relative term) a good majority of the course.

    1. Meghan Hicks

      Hi lori,

      Good luck at the Moab 240!

      The biggest changes I have found in doing longer efforts–I’m thinking of my outings of 34 and 38 hours at Hardrock, 59 hours at the Nolan’s 14, and something like 137 hours at the Tor des Geants as I write this–are in the types of food I can tolerate/want to eat as well as the quantity.

      First, the types of food, and namely eating a lot more real/non-running-specific food. At both Hardrocks, I still ate running-specific food (gels, chews, stroopwafels, powdered drink mixes) in between the aid stations, but at the aid stations I added in real food via what my crew had for me and what looked good at the aid stations. This included mashed potatoes, various soups, quesadillas, potato chips, fruit, etc. Nothing special here, typical aid station type food, but I think the key was generally carbs which take a little bit longer to digest than running-specific food, to create a full/sated feeling in the belly.

      At Nolan’s and Tor des Geants, in addition to the real food I ate in aid stations which was generally in greater quantity than at Hardrock–I sat down and ate full-on meals several times during both–I also had real food with me on my person, which I ate while hiking and running, stuff like pasta, mashed potatoes, rice, pieces of avocado, nut butter packets, chocolate bars, chunks of cheese, and etc. In all this food there are, again, those carbs which take a little longer to digest as well as a lot of fat which creates that full-belly, warm-from-the-inside sensation.

      One last thought on the types of food for these longer outings, I have found that listening to what my body is craving/doesn’t want to be a good way to choose my foods. For instance, coming into an aid station at Tor des Geants, I’d look at what was on the table and some things looked really, really good while others my body was like, “Nope, don’t eat that!”

      Now, quantity. If you’re moving along in your typical middle-ground aerobic zone (like in a shorter ultra), you’ll only be able to digest between 200 and 300 kcals of simple carbs (in multiple forms) per hour. But when your effort is easier during these longer outings, you can not only eat more calories overall per hour but you can also digest something aside from just simple carbs. I have found that I have needed to be careful with how/when I eat more complex carbs and fats on the trail, though. Bad times for me to eat these things: higher altitudes, when I feel hot, on sustained climbs that last an hour or two, during a significant flat section where I am jogging along the whole time, and in the couple hours right before dawn. (I am still carrying running-specific foods to eat during these times.) Good times to eat this stuff: downhills, lower altitudes, when I feel cool/cold, rolling terrain/when the climbs are shorter, later mornings, and dinner time.

      I would recommend you experiment in training while simulating race-day(s) conditions, including your effort. Maybe on a very long training day where you’re doing lots more hiking than usual mixed in with your running, or at night, etc.? To see what you enjoy and can eat when the effort is eased down to 240-mile pace? Also, perhaps taking some time to think back on what have been your ‘comfort foods’ over the years might help, such as what foods from your childhood you love, what you eat when you are sick, what you’ve craved during your previous long ultras.

      I hope this helps and keep us posted on what foods end up working and not working for you!

    Dear Meghan,
    Very interesting posts!
    I will run soon the Marathon des Sables and I would rather not taking fuel to cook and would like to use the sun instead. Mashed potatoes is a very good option and I like it but it seems that the mashed potatoes package that we found in the market do not have enough calories, what other food would you recommend?
    Thanks for your feedback!

    1. Meghan Hicks


      Ah, best to you in your Marathon des Sables preparations and adventure. You’re going to have an amazing time!

      First let’s talk about how you can spruce up your mashed potatoes. Consider what you can add to the mashed potatoes to not only add calories but add enjoyable flavor. First, dehydrated potatoes will be your meal’s carbohydrate base, but they haven’t much fat or protein. So, ideas for fat based calories: powdered butter, powdered coconut oil, powdered cheese, powdered avocado, powdered sour cream. Ideas for protein based calories, freeze dried bacon, freeze dried beef, freeze dried pinto beans, freeze dried eggs. Then consider what spices you might want to add to create flavor, such as garlic or onion powder, dried chives, dried parsley, curry powder, dried sage. Ahead of time, consider buying some supplies in bulk and experiment with combinations you think you might like, making them for meals at home.

      As for other food, couscous based concoctions are great for cooking with the sun at MDS, as are some of the traditional freeze dried full meals that many companies make. If you go the already made meals route, take care to watch your ingredients so that you’re choosing meals that have the macronutrient count you’re seeking in addition to tasting good. Also, I advise choosing freeze dried meals with a low sodium content and then bringing a bit of salt to flavor your food. Some freeze dried meals have very high sodium content, way above some people’s daily intake, and this could throw your hydration and electrolyte status out of whack, which you definitely don’t want to happen at the MDS.

      Some snacks that I have used other years at MDS and have enjoyed are freeze dried fruit, dehydrated vegetable chips, and nuts of various kinds.

      I hope that helps!

    Hi Meghan –

    A big fan of iRF & you! I saw you at the 2019 PP Marathon – love the interview with Sage. I ran the PP Ascent and watched the marathoners on Sunday.

    A bit of back story about my ultra bug – I stayed at Barr Camp on Dec 25-27, 2017 during my 3 week trip to the west from NJ. At Barr Camp, I learned about ultra-marathon from a caretaker who was covering for Zach Miller – until that point, I had no idea what an ultramarathon was and never heard of Zach.

    In Aug 2018, I ran my first 5k, my first ever race at the age of 56, and ran a few half marathons and completed my first ultra, a 50K in Dec.

    In 2019, I logged 2070 miles and 27 races, including 3-50 milers, R2R2R & 3 days later the Bryce 60K, 3-marathons and several 50Ks, and DNFd a 100 miler after 40M due to an injury. My first ever marathon, I qualified for the Boston by 14 minutes for my age group – thus, I am running the 2020 Boston.

    Last week, Jan 12th, I got an email from MDS that my entry has been accepted. Well, a week after the MDS race, I will be running the Boston Marathon & in June, the Comrades in S Africa. I will be 59 in March and everyone around me are telling me to go check my head!

    As I am scrambling to prepare for the 2020 MDS, packing and training, I find your articles in iRF so helpful. You sharing your packing list, training and your personal experiences to others is amazingly kind and thoughtful. I hope you are running this year, if you do, I will certainly stop by and thank you in person!

    Hope you have a great running season & stay healthy!

    I went and bought a lot of freeze dried meals and as I was leaving the store I was thinking about the weight and I still need a bit more. After reading this, I am definitely going to find out what works and doesn’t. I truly like the food list you’ve laid out and will be trying it also. Thanks for the article.

    Hi Meghan,
    Really appreciate your posts for this race, they’ve helped me prepare my kit a lot better than I think I would’ve done alone. Question on the mashed potatoes; I love them too, I eat them all the time after long runs and I’d like to bring them with me in April like you did. Would you mind sharing what kind of dehydrated mashed potatoes you used? There are more kinds available than I was expecting, and I’m not sure if the 4oz Idahoan mashed potato mix bags I typically eat after a run would cook okay in this way.

    Thank you!
    – Adam

      Hi Adam,

      Thanks for the comment and kind words!

      Any kind of commercially available dehydrated, flaked/crumbled/powdered mashed potato (generally marketed as instant mashed potatoes) should work great for putting your MDS meals together. I’ve used a lot of different kinds of instant mashed potatoes over the years with my non-MDS backcountry travel and prepared them by adding water and sitting them in the sun. I’ve even eaten them in the backcountry cold, by pouring water into them, waiting a few minutes for the water to absorb, and enjoying. In fact, I have a couple lovely memories of sitting by mountain streams midway through a long day afoot with a bag of instant mashed potatoes and cold filtered stream water and it tasting heavenly. ;-)

      Just make sure to test your favorite brand at home by simply adding cold water and letting it sit for an hour or so on your countertop before trying. While you won’t have the warmth factor from them sitting in the sun, you will be able to test the consistency of a particular brand upon its rehydration.

      I was extremely lucky to be working with Gu Energy in the development of my food for the 2019 MDS, and they produced their own hand/homemade dehydrated potato flakes for me to eat! If you are really into it and have a food dehydrator, you can make your own, as well! I’ve never tried making them myself, though.

      I hope this helps, and good luck to you at the MDS this year. You will so enjoy it!
