The Myth Of The Sub-2-Hour Marathon and Pacing, fatigue and the brain. Lessons from London
With the articles on the front page (and above) discussing the possibility of the 2 hour marathon, I just added some info to Robert's article.There should also be a thread on this as well so that's this one.
Here's what I wrote:
"I'll present my argument much quicker. To run under 2 hours in the marathon, one has to average 14:13 per 5km split. The Virgin London Marathon had arguably the best men's field in the history of marathoning. The field was decimated by strong early pace. How many 5km splits did they run faster than 14:13? NONE. The fastest 5km split was the downhill opening 5k and that was only 14:23. For a 2 hour marathon we essentially need 8+ back to back sub 14:13 5ks, and the top marathoners in the world got decimated by a pace where they didn't even run 1 of these. We're a long way from a sub 2 hour marathon on a legit course (with the perfect 26.2 mile decline off a mountain you might be able to get one now), barring some radical breakthrough in training.(I don't count wonder drugs)."
PS I don't think anyone has ever split sub 1:01 for a half marathon in a marathon."
So those are my thoughts.
Also we should start tracking marathons where any runner has run a sub 14:13 split. Has it ever been done for 10km straight? If you know of a sub 14:13 split post it here.
And what is the fastest half in a marathon? We should start chronicling any halfs in a marathon under 1:01 for sure. I don't think that's been done but it's early in the AM here so I could be wrong.
