Post-Ultra Downtime: How Much is Enough?

Valuable tips on how to determine whether to and how much time to take off after running an ultramarathon.

By on October 3, 2023 | Comments

Many of my articles for this column have focused on how to get yourself to the finish line of an ultramarathon in the most efficient and effective way. Today, I want to tackle a different dilemma: How should we recover from an ultra and, specifically, how much time should we take off from running?

A common formula states that you should take one day off for every mile raced. For example, a marathoner would take 26 days off from running after race day. This well-intentioned and conservative guideline was developed to prevent burnout and injury after hard efforts. However, this principle doesn’t seem to translate to the ultrarunning world. How many ultrarunners do you know who purposely take three or more months off after a 100-mile event? I’ll also note that many non-ultrarunners, including Olympians and world and national champions, do not adhere to this conventional wisdom. So, this begs the question: Is there an individualized method we can use for determining our own post-ultra downtime?

The answer to this puzzle and one that you’re likely to hear from an experienced coach or ultrarunner is simply, “It depends.” There are a multitude of factors that play into your post-ultra recovery time. Their impact will vary from ultra to ultra and year to year. Let’s examine the most significant elements that will influence when you can return to running or if you even need to take a break at all.

Running and Racing Experience

We practice a skill or task in the hopes of becoming more proficient at it. Running is no different. If challenged frequently, year after year, the body and mind will become efficient at adjusting to and recovering from the demanding rigors we place on it. Runners who’ve accumulated countless hours of consistent training and racing time will recover faster than runners who have just completed their first ultra.

Arlington, Virginia’s Michael Wardian, who ran across the United States in 2022, holds the Guinness World Record for seven marathons in seven days on seven continents, and has previously set records for the fastest 50 kilometers on a treadmill, is world famous for his prolific racing. Wardian started running after graduating from Michigan State University and completed his first ultra at the age of 24, at the 1998 JFK 50 Mile. The race was difficult and left him battered. It wasn’t until 2008 that Wardian found his groove in ultramarathons. “That’s when I won the USATF 50 Mile Trail, 50k, and 100k National Championships,” recalls Wardian. “Up to then I only dabbled in ultras because they were so tough. I got sick at a few and got lost at others. Between 1998 and 2008, I competed a lot, but my focus was on building my speed in marathons, competing in triathlons, and participating in stage races, like the Marathon des Sables and Himalayan 100 Mile Stage Race.” Whether he knew it or not, Wardian was developing his soon-to-be utilized ultra  fitness, while focusing on these other events.

Until 2008, Wardian averaged two or three ultras a year, but as the years passed and his experience grew, he began racing more — up to 50 times a year, including 10 to 15 ultra-type events — and doing fastest known times. “I love to race so I’ve always pushed my recovery, even when I was younger, and fed off of each race finish. Now, I’m used to it. Both my mind and body are accustomed to my current racing load.”

Of course, Wardian’s situation is unique. He’s able to maintain his desire to race frequently (an element we’ll touch on later), he’s supported by numerous sponsors and a loving family, and has a career that grants him the time he needs to travel and the ability to work remotely. However, Wardian’s example proves that a mature running background can certainly alter the common recovery paradigm.

Bottom Line: If you’re familiar with running with fatigue and soreness and can do so without injuring yourself, then easy running the days after an ultra is permissible. However, if you’re a newbie, enjoy your accomplishment, rest up, and take up to a week or three off before returning to some easy running.

Injury History

Let’s face it, the human body isn’t built like a Mack Truck. It’s a delicate piece of equipment. Athletes who are prone to injury should take a conservative approach when they return to training after an ultramarathon.

Susan Donnelly, who has completed more than 260 ultramarathons, has battled just about every running injury. “The worst injury I’ve had is a slipped disk in my neck,” says Donnelly. “But my most common running injury is a sacroiliac joint that likes to slip out of place. I lose power in that leg, and it hurts to sit, too. I had a freak stress fracture one year and pulled my hamstring almost immediately after that. I also end up with a bout of plantar fasciitis every five years or so.”

Donnelly races frequently. She completed nine 100-mile races in 2022, but she’s also missed an entire season due to injury. “Yes, I’ve had to cancel many races due to injury,” admits Donnelly. “I really must pay very close attention to my mind-body-spirit connection to make sure this doesn’t happen. My body often feels incredibly perky a couple of days after an ultra. It’s important that I ignore that feeling and instead focus on non-running activities like my life coaching business, spending time with family and friends or finishing projects around the house. Giving in to temptation and running on those days inevitably causes a big crash or pain a few days later that sets my recovery way back.”

Ensuring that muscle, tendon, and bone are adequately prepared to resume training will pay dividends by preventing months of lost training due to unnecessary strains, pains, or breaks. If you fall into a chaotic injury pattern or experience an odd post-event niggle, then it’s paramount that you take proper precautions, namely, more time off from running.

Bottom Line: Running with pain is not normal. If it hurts or if you suspect that it’s going to hurt, seek the advice of a professional and take the extra time you need to recover. Cross train (elliptical, cycle, swim) while the issue mends itself.

Post-Race Malaise

Where there’s a will, there’s a way. But what happens when there is no will? Believe it or not, it’s quite common to find yourself burned out, fatigued, and sore after an ultra. As a result, running may be the last thing on your mind after a race. Respect these feelings. Take the time you need away from the sport to recharge.

As one of California’s dominant masters ultrarunners, with PRs of 3:19 for the 50k and 14:54 for 100 miles, Jean Pommier frequently puts in back-to-back hard efforts. For example, in 2014, in the span of two weeks, Pommier placed third at the Miwok 100k and won both the Quicksilver 50k and Silver State 50 Mile. Does racing in such close proximity affect Pommier?

“I do experience lassitude,” says Pommier. “But I’m a big believer in leveraging variety for sustainability. This helps me to control that lethargy. I mix road and trail, flat and hilly courses, race distances, pace and rhythm, and use some ultra races as long training runs.”

As a result, Pommier’s mental outlook stays positive. “I used to take a week off after a race but barely take any time off nowadays, at least after sub 100-mile races,” says Pommier. Besides the way he mixes up his races, he’s developed a few other methods for maintaining his enthusiastic training and racing attitude. “I record all my running in a log to keep me motivated and to track my progress, goals, and metrics,” says Pommier. “I also set follow-up races. I have a slew of events scheduled and entries paid for, which force me to get out and to move forward.”

As inspiring as Pommier’s successive performances are, not all of us are going to want to jump back into another ultra as quickly. Simply remaining idle is a perfectly acceptable post-race activity.

Bottom Line: If you are looking forward to running the day after your ultra, do it. Please take it very easy. If you’re not in the mood or promised yourself or others some time off, take it. Two to three weeks should do the trick.

Race Preparedness

The training and planning you invest in before your event plays a huge role in how you’ll come out on the other side. Keep in mind, however, that overtraining is as detrimental as insufficient training and either will negatively affect post-race wellbeing. Donnelly, Pommier, and Wardian represent a rainbow of preparedness.

Donnelly enjoys moderate mileage, avoids speed and tempo work, but uses partners and terrain to add challenge. “I average about 55 miles a week on non-racing weeks and always take one guilt-free day off a week from running. I live in East Tennessee, where hills are easy to come by. Typical long runs range between 15 and 30 miles and I’ll join friends or head to the Great Smoky Mountains.”

Pommier takes his training a step further by adding intensity and occasionally flirting with higher volume. “I run five to seven days a week. These past four years, I’ve averaged 62 miles a week, lower when tapering for or recovering from a race, but I’ve had several 100-plus-mile weeks,” recalls Pommier. “I do speed workouts with a few buddies twice a week where we’ll accumulate three miles of fast running.”

Wardian, as predicted, logs consistently high mileage, but doesn’t add intensity until it’s necessary. “I average between 50 and 90 miles per week. I run daily, and every day, I do something besides running. I am a huge believer in strength training and work out five to seven days a week along with cycling and pickle ball,” says Wardian. “I would say my typical long run when I’m not racing is between 18 and 22 miles. I’m not doing a ton of specific speedwork at the moment, but I do shorter races most weeks. I particularly love the 5k distance to keep the legs ‘fast.’ I’m getting ready for a big run in 2024 on the Appalachian Trail and a bikepacking race across New Zealand. I will always keep things fresh and fun as this allows me to really love the process.”

Donnelly, Pommier, and Wardian have each found their own balanced training capacity. It’s their own individualized mix of variety, specificity, and difficulty that allows them to maintain their fitness, begin each race with confidence and finish in decent shape.

Bottom Line: Smart training reduces post-race downtime. Build a resilient ultrarunner’s body by finding your own training sweet spot.

Race-Day Intangibles

Ultramarathons are unpredictable. Rarely do things go as planned and when they don’t, long days on the trail or road take their toll, leaving us deeper in the recovery hole.

Pommier has been known to bench himself for several days after an ultra because of extraordinary race-day unknowns. “There have been several things that have set me back,” says Pommier. “Exercise-induced asthma, falling short of my race goals, being unprepared to run through the night, and bad cramping during the race.”

Donnelly takes as little time off as possible after races. “Active recovery is best for me,” she explains. “Ideally, I try to get out and walk or jog as much as I feel like doing the day after a race. The purpose being is to get the blood flowing, loosen up my muscles and joints, and assess any damage.”

One of the reasons for her quick rebound may be that Donnelly’s efforts aren’t as hard as in years past. “Racing is frankly not the main reason I’m out there anymore,” admits Donnelly. “I’ve managed plenty of wins in my time and it’s nice to step back and let someone else have their day. I’m really there because I love running trails in beautiful places with a bunch of like-minded people.”

However, there still are factors that affect Donnelly’s post-race condition no matter how aggressive she is on race day. “The race distance is a biggie,” she says. “I just have to assess how much time the race has taken away from other priorities and how worn out I am. Bad dehydration, a broken bone in my hand, and a stomach bug have also prevented me from running.”

Take a page from these consistent and talented ultrarunners by opting to skip a few days or weeks of training in favor of healing the inevitable bumps and bruises incurred on race day.

Bottom Line: Ultras aren’t easy. Expect to be thrashed even on a good day. When you have a bad day, remember that it will impact your recovery. Take inventory of how you feel and take the necessary amount of time to heal before moving forward.

Consider taking time off from running at the end of your racing season. A month or two away from running resets the body and mind for next year’s competitive calendar. Many ultrarunners are reluctant to take a vacation from the sport for fear of losing hard-earned fitness and perhaps missing out on an epic event.

Pommier experimented with taking an off-season. “I used to follow Scott Jurek’s advice by taking December off,” says Pommier. “But the following season was always an issue, leading to nagging injuries. I may have had a tendency to resume training too fast to get ready for early season events. These past two years I barely stopped for a week and things have been better.”

Wardian and Donnelly are no different. “I don’t have an end of season,” replies Wardian. “I race anywhere, anytime, in any climate, any time zone, and as much as I can.”

“Nope,” says Donnelly. “One of the joys of today’s world is that there are so many races now; there doesn’t have to be an end of season like there used to be when races weren’t as prevalent.”

Bottom Line: Off seasons may be unnecessary unless you have a nagging injury or are experiencing burnout. On the other hand, a break from ultra-distance races and high training volume will keep you running while recharging the proverbial batteries and providing the time necessary to improve weaknesses. Consider taking a few months to focus on shorter races, develop your speed, and build your strength and agility.

Putting a Number on It

There is no cookie-cutter post-ultra recovery program. Some ultrarunners get back to running the day after their race while others disappear for weeks. Successes and failures have been derived from both these recovery extremes, as well as all points in between. It’s not whether we run or not, but how we interpret the cues our bodies give us after a hard, long effort that affects the quality and quantity of our post-race activity.

  • How do you determine how long you’ll take off after an ultra? Does it vary from race-to-race and, if so, how?
  • Do you take an off-season from racing? From hard training? From running altogether?
