Walmsley vs Kip wrote:
If the course would be flat with good weather and good pacers through 50-60k i think he could run 5h30' right now. 5h40' in the worst case scenario. Also if he took a year to fully concentrate on it i could see him running 5h20' maybe 5h15' if he nails a perfect race scenario. A 6h 100k would be a dawdle to Kip.
This is one of the age old classic debates. To resolve this, a race format was set up in the 80s called "The Ultimate Runner" with prize money where I believe runners ran every standard race distance from 400m to the marathon in a single day, and were scored based on how far off the WR they were in each event. See John Parker Jr (Once A Runner)'s "And Then The Vulture Eats You" for more info on that race.
Is the question what Kipchoge's fitness translates to or what he could actually run right now? Saying Kipchoge v Walmsley is a bit silly. We saw today with Jim what literally happens time after time to strong ultrarunners in the 100km, even those with experience going longer. 5:30 in a lab isn't crazy, but neither is breaking 2 in the marathon. Actually executing is another story. Some people say anything can happen in the marathon. That's debatable, but there's no question that the longer the race, the more that can go wrong, and today was a classic example. Even if Jim were to have run 5:50 today, it would still pale to EK's 2:01:39 in Berlin. How would EK do in the 100km? Anyone's guess, but rest assured, that anyone who is confident in any position (any which way, including this statement), is wrong.
