Eliud Kipchoge is a physiological marvel. The Nike Vaporfly is a technological marvel. Both improve marathon performance. Except these statements can’t both be true, and the implications for the integrity of running and how we evaluate performances, can’t be ignored. This is an article on why that is.
Where do we go next? Now that Eliud Kipchoge has taken us to the brink of a sub-2 hour marathon, have the boundaries of human endurance been recalibrated? Can we expect a 1:59 soon? Or did the Nike staged event simply move some of the boundaries aside? This piece looks at potential benefits, and asks whether we should expect to see a speeding up, or a slowing down, in the foreseeable future?
Eliud Kipchoge has run a marathon in 2:00:25, coming within sight of breaking the 2-hour barrier. How did he do it, and what might we expect in future? This post analyzes the splits, the tactics and the prospects for the 1:59:59 in the future.
The Nike-Breaking 2 attempt will happen in Monza this weekend. I don’t think a sub-2 is possible, but what will be fascinating is to see a) how they go about pacing the attempt, and what happens if it starts to fall away; and b) what the collective advantage is of all the tactics employed. I predict 2:01:55 at best, a DNF is also a real possibility. More thoughts here.
Nike recently unveiled the Vaporfly Elite, the shoe it has been working on to help it break the 2-hour marathon barrier. The shoe incorporates a “spring plate”, and is claimed to have significant performance implications. I think the shoe, and the incorporation of spring-like devices in all shoes, should be banned for future credibility of performance. Here’s why
