Jon Olsen’s North American 100-Mile Record Report

[Editor’s Note: Previous to last Saturday, the American 100-mile track record was held by Bernd Heinrich at 12:27:01, a record that had stood since 1984. The previous American 100-mile road record was held by Rae Clark, who ran 12:12:19 in 1989. And the overall North American 100-mile record was 12:05:43, set by Canadian Andy Jones in 1997 on a road course. But last Saturday, at the 2013 Sri Chinmoy Self-Transcendence Annual Ultra Classic 24 Hour race in Ottawa, Canada and on an indoor track, Californian Jon Olsen set a new North American 100-mile record of 11:59:28. Here is his story.]

“The IAU 100k World Championships have been cancelled.” These infamous words were uttered for the second time this year. First, when the original host country, South Korea, had to cancel and now South Africa was unable to host either. It was now August, and with a third and final attempt at saving the 100k World Championships in the hands of The United Arab Emirates (Dubai), it was time to make alternate race plans.

I had been allowing my body to heal from the 24 Hour World Championships in Steenbergen, the Netherlands in May. I won that race on an injured body, and because of that, I required more than usual recovery time. I resumed training at the beginning of July. This would give me enough time to build back the base I had lost and then have August and September to train hard and peak for the scheduled 100k World Championships at the end of October, although they were just hanging on by a thread. It was now August and with the 100k very much in doubt, I was forced with a dilemma. I knew my body would be in peak shape near the end of September and if the 100k did not matriculate, then what would I do? Would I ‘downshift’ and save my legs for the Desert Solstice 24 Hour in December, which I already was registered for or would I race now (September) while my body was healthy and in good race shape?

Good health is never guaranteed and, at 39 years of age, my GREAT performance clock is ticking, so I decided to race in September at the Sri Chimnoy Ultra Classic in Ottawa, Canada, if the 100k was not saved.

Well, lo and behold, we received the news at the end of August that the 100k was going to happen and that the race would be held on December 20th in Dubai! My initial reaction was disappointment because one of my goals this year was to attempt to break the 100-Mile American Record (12:12) set by Rae Clark back in 1989 and I was going to do this in Phoenix at the Desert Solstice 24 Hour track race. Obviously that would be out of the question if I was in Dubai at 100k Worlds. At Desert Solstice last year, I ran 12:29 and knew with some minor changes, I could make a better attempt at the record. Now, I would have to cancel my plans to go to Phoenix, but I wasn’t ready to cancel my goal of breaking the 100-Mile American Record.

With twelve weeks between the Ultra Classic 24 Hour and the 100k World Championships, I had enough time to recover and help Team USA to a gold medal in Dubai. However, I soon found out that the dream of gold would have to wait. The drama of the 2013 IAU 100k World Championships was finally over one week later when it was cancelled completely.

The focus was now solely on the 100-mile record. For the first time that I can remember, I enjoyed the two-week taper. I finished this taper period with a 1:18 half marathon at the Peace Officers Memorial Half Marathon in my home town of Modesto just six days before the big day. I used this race to ‘wake up’ my fast-twitch muscles. I wouldn’t be telling you the truth if I didn’t say I was a little… I mean… a lot nervous to run so hard so close to my 100-mile attempt.

I made my final travel plans and, with the addition of my wife as crew chief, I was ready to go to Ottawa. This would be the first time, except the 2012 100k World Championships, my wife had crewed for me since our two children were born. To say I was excited to have her by my side each and every lap was a huge understatement.

After taking a red-eye flight from San Francisco, we arrived in Ottawa early Friday morning. We were able to check in early to our hotel and had an enjoyable 30-minute, shake-out run together near the hotel. We followed that with lunch, a last-minute grocery stop, and a much-needed nap.

We awoke three hours later and made our way to the Louis-Riel Dome, the site for the pre-race check-in and the indoor track that I would get to know intimately in the course of rounding it 402 times! While at the Dome, I met up with my running mentor and 12-hour participant, Mark Dorion, who finished third place in his race. A couple issues that occupied my thoughts the evening prior to the race were the temperature inside the Dome, restrooms, and where to put my aid table.

You would think that, because this was an indoor track, the climate inside the Dome would be relatively consistent; however, no air conditioning or heating would be used during the event, so the temperatures would fluctuate depending on outside temperature and those forces inside the track. With 70-plus runners on the track for the warmest part of the day, a 77-degree Fahrenheit high outside, a soccer birthday party, and an adult soccer game on the infield, it heated up noticeably during the day. I made sure to bring enough S!Caps and make water consumption a focus. Although I don’t frequently run shirtless, I knew the shirt would come off at some point during this race.

Obviously, in a race such as this, you don’t want to waste any precious time. Restroom stops are one of those necessary, but dreaded, time wasters in any race. I knew I may need to use the restroom about three times during the race. However, there were no track-side restrooms. The restrooms were located through a revolving door and down the hall. This wasn’t an option. I needed to come up with an alternate plan. Facebook friend Rose, a past runner of this race, got wind of my trip to Ottawa and recommended getting a bucket that I could put track-side. As obscure as this may have sounded to the average person, it was a fantastic idea! My wife also suggested I buy a handheld urinal. The two in combination would do the ticket.

My wife and I spent some time walking around the track looking for an ideal spot to set up the ‘potty rest stop.’ After carefully propping up some exercise floor mats, our outhouse was finished. Next, we placed our table in the middle of the front turn. This would allow my wife to see me from either direction of the track and put her in the center of the friendly crew area which would help pass the time.

It goes without saying that, from the moment I arrived at the race, I was treated like royalty. The Self-Transcendence race staff provided me with a table and chairs to use during the event, but more importantly they made me feel like we were part of a team. They wanted to do all they could to help this record happen. After a late dinner, at 8 p.m., we headed back to the hotel for bed as the 6:30 a.m. wake-up call loomed over us.

Panic struck me as we stood posing for a picture at the start of the race. I reached to change my watch from time to chrono and the band broke. I thought, Are you kidding me? I needed the watch. There was no way I could stay on pace without it. I decided I would just have to hold it. If I could hold two full water bottles for 20-plus hours, I could certainly hold a watch.

Within seconds, the gun went off, and the 402-lap journey began. What made this 100 miles different than any other 100-mile race in the past was my pace. I knew I needed to run around 7:15 per mile to break Rae’s record. This meant I would have to run uncomfortable from earlier on in the race than I usually liked to. I would basically be racing from the gun. There was no easing into the pace.

The first hour or two went by rather quickly and uneventfully. My pace hovered between 7:10-7:15 per mile. I was grabbing some water about every other lap and would drop my bottle at the end of the turn on the infield of the track. After I did this three times, my wife would go pick up the bottles and repeat the process.

My fluid of choice was solely water, with S!Caps serving as my primary electrolyte replacement. Obviously, calorie consumption is of utmost importance early on in the race while your body isn’t taxed and the stomach can digest more efficiently. I consumed a Vespa every two hours and then tried to rotate starch, salty/fatty, and sugary foods every 20 minutes in small amounts. I would stick to this plan the entire race. My foods of choice were cold instant mashed potatoes, gel, chips, and gummy worms with some chocolate thrown in as well.

Track races are perfect for my ‘OCD’ mentality. I checked the splits on my watch each and every lap and it kept me focused and motivated. Moreover, the constant encouragement from the other 70-plus participants, the sight of my wife each lap, and hearing my mentor and biggest cheerleader, Mark, from anywhere on the track as he shared his running knowledge with fellow runners, was amazing.

As I ran around the track, lane one would part like the Red Sea. Everyone knew how precious each second could be. I came through 50k in a comfortable 3:43, and 50 miles in 5:58 right before we switched directions.

At that point, I felt so good that I had my wife begin to cut up my Hokas so they would ready for after I finished the 100 miles. I had a secondary goal for the race. If I felt good I wanted to run all 24 hours and take a crack Mike Morton’s American 24-Hour Record. On a side note, the lady crewing next to my wife, who was a Canadian, was beside herself when she saw my wife cutting material out of the toe box of my Hokas. She couldn’t believe someone would do that to a pair of $170 shoes because it’s hard for them to get Hokas in Ottawa. She really looked angry and had a talk with me about that after the race.

Well, the 24-hour feeling was short lived as I hit 100k in 7:28. I had a feeling this was where the race was going to start. Doubts, for the first time, were starting to creep into my head as the pace was starting to take its toll on my body. My hip flexors and feet were aching. The hamstrings were tightening up. The effects of the humidity were starting to show as the salt was starting to accumulate all over my body. It was time to take the shirt off and try to cool off. I slowed slightly as I literally ran into my running shorts that I had to don to hold my bib number after I removed my shirt. I asked my wife for a 5 Hour Energy, and for the first time, I asked for my iPod. It was time to get serious. It was going to be a 4.5-hour grind. This was uncharted territory for me. I wasn’t used to having to work so hard for so long. I wondered if it was even possible to run 7:15 splits the rest of the way. Should I back off a little as I had banked some time early in the race? I was here to do one thing and that was to break the 100-mile record so I decided to push on and nothing else mattered. Now that I knew I wasn’t going past 100 miles, there was no reason to save anything in the tank. If I was going to break the record, then I would give it my all!

If I could maintain what I was doing, I could possibly break 12 hours. This was very motivating. My pace did not slow. It actually held steady at about 7:05-7:10 pace. I was holding on to each mile split for dear life. I just didn’t want to give in to the pain. In my experience, pain is not an indicator of when to back off but heart rate is. Since my breathing was under control, I pushed on.

As I headed into the last hours of the race, I felt like I was redlining. The talking stopped, I called, “Track!” louder, and my eyes were pointed down at the track instead of ahead like earlier in the race. In addition, I handed the nutrition keys over to my wife. I told her she was in charge of when I ate. Whatever she handed in front of me I would eat. I told her Coke, Vespa, and mashed potatoes the rest of the way. That was it!  I made my last pee stop at seven hours and wasn’t stopping until the end.

The mental mind games I played were fierce, but I grabbed onto any motivation I could find. It could be a lap split, a mile split, 20, 15, 10 miles to go, or any encouragement from spectators. The motivation that had pushed me along for laps earlier on now pushed me only a few feet. I started to realize that no one was going to make this happen but me. It was just like when that alarm went off on any given morning at 4 a.m. for my daily run. I had no one to meet me or tell me to get up but myself. I was either going to get this record or not.

With a marathon to go, I had 3:10 to break 12 hours. I knew that was a 7:12 pace. So each lap I focused on maintaining that pace. With 10 miles to go, I had 1:14. With 8 miles to go I had 58 minutes. It was going to be close.

I could see my lap counter, Sanchita, working nervously with other staff to make sure each lap was counted. This nervousness was motivating. They could sense what was about to happen. They weren’t the only ones; you could see it on my wife’s face. She was trying to remain calm as she had been all day, tirelessly tending to my every need, but she was a duck in water. The people in the crew area were abuzz. Lane one was almost completely empty as the runners knew what was taking place. As much as I wanted to admit that the record was mine, I’ve been in too many races to know that the wheels can fall off without warning. You take nothing for granted in this sport.

With each lap, that once-imaginary finish line became more and more real. With one mile to go, I could finally see the finish line and dug deep for four victorious laps. The thought of doing this feat in front of my wife, the one that has sacrificed so much to make this happen, and Mark Dorion, the man who single-handedly introduced this sport to me and has mentored me through the good times and the bad, almost brought me to tears as I rounded the track a couple more times.

It is amazing what the sight of the finish line can do. All of the sudden, my legs didn’t ache, my stride became longer, and each breath became effortless. I was going to finish this race just as I started it. I rounded the final turn and headed to the back turn where the 100-mile finish would be. With my fists pumped in the air and my wife cheering me on, I crossed the finish line. This signified the end to 12 of the toughest hours I’ve ever run. And to think, my name will now be listed as the 100-Mile American and North American Record holder is unreal.

Records are meant to be broken and I know this mark will be broken in the near future, but to say that I am the fastest American EVER to run 100 miles is so rewarding. However, it doesn’t define me as a runner and certainly not as a person. I often get asked these days, “What is your training like?” and “What do you eat?” And though my training and diet have changed through the years, I think the difference is this: I don’t race in search of something. When I race, it is a celebration of what God has bestowed upon me. He has given me a gift that allows me to do things with running that I never thought possible.

    You are one of the classiest individuals I know. You deserve every bit of the fame and the honor that the world is bestowing on you. You are an amazing athlete and I am in awe of all that you have achieved in the past few years – a result of your dedication, talent and physical and mental strength.

    May you continue to soar even higher!



  2. olga

    Absolutely awesome, ow-striking and inspiring, the story, the focus, determination, and the "why" at the end. Heartfelt congrats.

  3. KenZ

    Oh. My. Sweet. Goodness. Holy. Frickin'. Amazing.

    And, thanks so much for the detailed report. I love all those inside particulars and logistics solutions. This was awesome.

  4. Aaron Sorensen

    I would love to see you and Mike M. have a perfect race at the 24 Hour World Championships and push each other (race) to a new 24 hour american record.

    That pace you kept was incredible.

  5. Tropical John

    For once words fail me. A truly superb performance.

    The best part is that – in a sport full of classy people – Jon is one of the absolute classiest.

  6. Vern L

    I loved this…

    "I just didn’t want to give in to the pain. In my experience, pain is not an indicator of when to back off but heart rate is. Since my breathing was under control, I pushed on."

    I've found that to be very true. Excellent effort Jon – I'm in awe of your accomplishment!

  7. Jeremy

    Incredible race Jon. I bet with the VESPA flowing that sub-12 hours was like a blink. If I were Yiannis, I would be nervous about the next time you line up for the 24 hour.



  8. Jean Pommier

    Jon, so glad your training and amazing effort paid off, what a great story and page you are adding to the US ultra history book! And in such a humble, human and smart way, pure ultra class! See you again soon on the trails!

    PS: also glad that Denise could be with you for such a wonderful experience. Love the image of the duck in the water… ;-)

  9. Duane VanderGriend

    I too run as celebration of God. But I still, run in search of something.

    Thank you for an inspiring write-up. What an amazing privilege and accomplishment! 100 miles faster than any North American in history. Awesome.

  10. Mark Tanaka

    Jon– Wowwowwowwow! No fading whatsoever– what a phenomenally amazing run! Thanks for writing up all the details on this one. Your GREAT performance clock hopefully won't run low too soon, cause it's GREAT fun watching you continue to pull off this stuff. PS, say hi to Denise.

  11. Peter Lariviere

    Jon, it was a pleasure and an honour to share the track with you and for you to break the record in my home town. You flew around so often and so fast it was nearly imposible to offer words of encouragement (on the speed issue you hit the 100 mile mark as I hit 50 miles…that is fast). I also think that your wife deserves a lot of credit and is an example of how crew support can make or break a record attempt. She also cheered on other runners as we slowly made our way around the track which was always good for a boost when the legs started to move slow. So once again congradulations on the new record and thanks for the running lesson. Oh by the way not sure if you knew this…there is an unwritten Canadian (specifically Orleans) requirement that for every km you plass someone you owe them a beer at some point. So maybe the next time we run at the same race I may speak with you about collecting my 80 bottles of beer…and it will need to be a Canadian beer of course!!!

  12. Charlie Taylor

    Jon, what an awesome race! You are the FASTEST 100 Mile American EVER!!!! Great job and great race report! Hope to run with you some day.

  13. Jon O.


    What an accomplishment. Superb effort and mental tenacity to stay the course and believe in the strengths and abilities that the good Lord has blessed you with. Unbelievable what the human body is capable. Good luck and congrats to your hard working wife. These records don't come without good support.

    From another Jon Ols(o)n

  14. Sean

    You hit 50 in 5:58, and 100 in 11:59…THAT is how to run a 100 miler, Mr. Consistency. WOW! This is such an incredible effort and performance, Jon. I remember all of the stomach issues you dealt with in the past, and obviously by how you've been running and kicking butt the past couple of years, I think it's safe to say that you've figured out what works for you and are now using it to propel you to such amazing performances.

    I must disagree on one thing that you wrote: "…I know this mark will be broken in the near future…". I'm not so sure about that. It's going to take an incredibly special day by a superbly trained person under the perfect conditions, and even then, well, as you said, the wheels can fall off without warning.

    Congratulations, Jon – North American 100 mile Record Holder! So, so, so happy for, and proud of, you.

  15. Melody-Anne

    Amazing performance Jon. Your shear determination and strong will to win prove how one can accomplish great things in life. I feel sure your motto must be 'Think Big Be Strong Run Hard' for a Champion like you.

  16. David Brady

    Wow this is awesome! Congratulations Mr. Olsen on the amazing experience and time!! Its awesome to say you were my 8th grade math teacher!

    Side note: I recently started running, and just think its funny that your 100 mile pace is my 3 mile race pace… Truly incredible.

      1. Jon Olsen


        I absolutely agree! It gave me chills. Teaching has allowed me to make connections with people I couldn't in almost any other job….very rewarding to say the least.

    1. Jon Olsen


      Great to hear from you! The good old AP/Gate class days:) Thanks for your comments. I'm glad to hear that you have taken up running. I hope you find a place for it in your life as you move forward.

      It is always great to hear from ex students….on irunfar…this is a first:) God Bless and stay healthy my friend.

  17. Dane Rauschenberg

    I am unsure what superlatives are left here but all I can do is shake my head. Epic and amazing and awesome are all words which are sorely overused in this day and age. They unfortunately fall short of being adequate here.

  18. Peter L

    Huge congratulations and thanks for taking us through your journey. It brought me to tears. While I suspect that there are quite a few who could physically match your feat, it takes an amazingly strong mind to run 400 laps on an indoor track. I suspect your record will hold longer than you think.

  19. Lstomsl

    Not to take anything away from this performance but reading this just makes Ian Sharmans rocky raccoon even more impressive. Only 45 minutes different between a trail and an indoor track over 100 miles. Wow.

    1. Ben Nephew

      I think most of us would prefer to be on a flat trail than an indoor track for 12 hrs. That was 804 turns in a warm gym. Pace wise, he was running about 30 seconds faster per mile, and at Jon's pace, he was 10k ahead at 12 hours.

  20. François R

    Hi Jon

    I've seen things in my life, but last saturday in Ottawa was the summum. I'm a runner too but I was so excited watching you passed in front of me for so many times. Congratulation Jon for what you did and your wife too, that i had the pleasure to speek with. I think seriously to get me a tattoo as your name and record.

  21. Anonymous

    Hi Jon.

    I had a lousy race at Ottawa but seeing you was truly inspiring. It was a real privilege to cheer you on over your laps and see the same encouragement for you from other runners. There were two races on that day – yours and everybody elses. To see an elite runner fly by during a marathon is cool but experiencing 12 hours with one is cool bananas! You rock dude!

  22. Ben Nephew

    Congratulations, Jon. Absolutely incredible. For those that know who Bernd Heinrich, Rae Clark, and Andy Jones are, you surpassed an amazing group of runners. Those that don't should do some research. Three of the best ultrarunners in the world during their time, and still world class decades later.

    While it may seem hard to imagine that time being lowered, Morton's 24 record certainly indicates he has the ability to put down a very fast 100 mile time. The conditions that Jon ran in were not exactly ideal; it sounds like the temperature was probably 20 degrees higher than ideal for a good part of the race.

    You took less than perfect conditions and made a perfect race happen through sheer will to take advantage of a fitness level I can't really comprehend. Nice work.

  23. Ben

    Somebody needs to say this: that is not a race. It's impressive, yes. No denying that. But this gentleman ran for 12 hours around an indoor track. Somebody occasionally needs to come onto irunfar and bring ultra runners back down to earth. Conquering just your own limitations is only a facet of racing, to actually be race needs to involve another human to push you and compete with you. Yes, I know this was some self-transcendence nonsense; go find an actual race that isn't in a dome. You are an impressive athlete, let me be clear, but I'd be more impressed if you battled in an natural environment against others of your caliber.

  24. Lstomsl

    I agree there is not much that I would less like to do than run 100 miles on an indoor track but still, I do run a lot faster on one.

  25. Andy Snyder


    Incredible run! I'm curious though. You said you ran according to HR. Do you use a monitor, or just go by feel? Either way, what was your average HR for this race?

  26. Lstomsl

    I agree there is not much that I would less like to do than run 100 miles on an indoor track but still, I do run a lot faster on one.

  27. Lorette Belland

    I was one of the participants in the 12hr in Ottawa and it was pure joy to watch you run.

    What impressed me the most was your kindness to us, the other runners, when we unknowingly cut in front of you to get to our table you were the one to apologize to us. You encouraged us as you past us.

    It was fun to see you run with Mark. I would like to thank you for the wonderful lesson in humility and greatness. Good luck in your other goals.

  28. Andy R

    I would also love to hear your thoughts on running and training with a hrm. I just started doing that but am very unsure of just what I should be doing. Thanks.

  29. Bryon Powell

    I'd speculate that the track was a 400 meter rather than a quarter mile track. With a mile being 1609 meters, Jon would have had to have run an extra 900 meters (or so) after running 400 laps to reach 100 miles.

  30. Jon Olsen


    You are entitled to your opinion. But it is completely out of line to make the comment "…this Self-Transcendence non-sense." That is completely classless. You don't even know these people…..and if you did… would realize how much character you are lacking.

    I have no problem with the comments directed towards me…BUT to attack a group of people that use there time to improve others is unnecessary.

    1. Andy Snyder

      Ok thanks. I've realized that in the few ultras I've done, I've started out with a heart rate too high, so now I'm really following the MAF method more closely and just keeping the HR down. I've often wondered what the average HR is for the top runners during a race.

  31. Meghan Hicks

    Ben, Jon Olsen, and everyone,

    I'm sorry that I'm belated in responding to this comment, but we've been mostly off the grid for a couple days in moving our home and iRunFar headquarters.

    To everyone,

    As Dane Rauschenberg said below, I beg the rest of us to not 'feed' this troll.


    Your comment is not only disrespectful to Jon's record and the track-racing community, but it also shows an erroneous perspective on ultrarunning.

    First, your attempt to discredit Jon's run based upon the fact that it happened without competition/in a race atmosphere is erroneous. He had several dozen other competitors with him on the track but none were capable of running his pace. Just like any other race, it's still a race even if the lead guy/gal is ahead of everyone else.

    Second, that you also attempt to discredit Jon's run based upon the fact that it took place on an indoor track shows your lack of understanding about the history of ultrarunning. Indoor tracks have been ultrarunning race venues for something like 150 years, so it's as "natural" an ultrarunning environment as any other venue our community uses today.

    Finally, you write with disrespect for Jon's run and the track-racing community. While you may not prefer racing on an indoor track, there are thousands of members of our ultrarunning community who do. Maybe you can let them enjoy their preferences while you enjoy yours?

  32. stevephoto

    Ben and nbskis whoever,

    Think about it. Scott Jurek, Mike Morton, Jon Olson, Yannis Korous, Stu Mittleman….you are kidding of course about your comments regarding circular track record attempts. A flat track for 24 hours of more is one of the most mentally and physically challenging feats of ultra distance running. Just ask any of these guys. No scenery or hills to break the monotony, fresh air (indoor track) give it a try so I can see what you can do!!

  33. Alex

    Agree on all points, Ben. Heinrich has an amazing book – Why We Run, formerly Chasing the Antelope – if anyone would like to know a little more about the former holder of this record. It was what first introduced me to ultrarunning, in fact, during my days working at a bookstore in college.

    Also, it's heartening to see great athletes, such as yourself, publicly celebrate this accomplishment. If a few of the comments here (and a few other places online) are any indication, too many don't respect "clock" races or track ultras. Hopefully you've changed a mind or two.

  34. Kyle

    Just curious. Were 402 laps completed or 402 laps + 134 meters? Because 100 miles is 402.335 laps. And, the extra 34 meters at 7:12 pace is 35 seconds, putting final time at 12:00:03.

    I really hope you did 402 laps + 134 meters.

      1. Jon

        It's all (ultra) running… Distance is the common denominator, not surface… Trail folks geek out over numbers/logistics just as much… Why can't we just congratulate Mr. Olsen, call it good, and go run :)

        1. Kyle

          It's more than good. It's amazing. Incomprehensibly good. Mind-bogglingly good.

          But, if it's a new world record and the first under 12 hours, it is legitimate to ask whether the necessary final 1/3 of a lap was included. I'm sure it very likely was and the article just rounds when mentioning 402 laps, but it's a legitimate question to ask, particularly as the 12 hour barrier was so narrowly beaten.

            I'm sure Jon will stop by later with more details, but I think this sentence "I rounded the final turn and headed to the back turn where the 100-mile finish would be." should answer your question that he ran the requisite extra bit of distance on the 403rd lap. If you've not been to an ultramarathon on a track or a small, looping course, you'll be heartened to know that race officials and competitors are obsessive about lap counting, measuring precise distances on extra laps run, and so on.

            Also, Jon's record is a new North American record, not a world record. The world record is held by Oleg Kharitonov at 11:28:03, which was set on a track in 2002.

    This is awesome! In the ultra-running community…when a person shows up to run they have shoes, shorts, shirt and their own abilities. It's so simple. Running on an oval speaks to physical and mental endurance. Jon obviously has an ideal combination of these features, along with a LOT of training that has allowed him to coordinate his strengths. My guess is, Jon has been up running mile after mile early in the morning before sunrise when it's hot, cold, rainy, and dark while the rest of us were sleeping. This is an amazing achievement and payment for all those hard miles. Congratulations.

    It was a competition- He was RACING against the clock, a good opponent as any in my opinion.

    I was there and I can tell you it was very serious business.

    If you want to compare times between Ian and John, you must also consider what the temp was.

    Ian had perfect weather at RR for him to "be able to" run that fast.

    If the temps were what John had to deal with, Ian would not have run that fast.

    Now if John had perfect weather, how much faster would he have been?

    Ian takes the more impressive time on a trail vs road time of John?

    It's hard to say who wins, but they are both the fastest in this country and both amazing.

    I would love to see the 2 of them meet at a 100 miler on the C&0 Canal tow path.
