The pursuit of the sub-2 marathon: Where to next?

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?

The sub-2 hour marathon attempt: The pacing strategy

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.

A thought crossed my mind: Knowledge & confidence, and “feeblemindedness”

Around 100 years ago, the world's leading scientists got together to discuss "eugenics", the idea that we could selectively breed "good stock" for the benefit of the human race. This happened openly, with the support of the USA's judicial system, and looks macabre and horrific in hindsight. It made me wonder about over-confidence, and knowledge, and how experts shouldn't ever profess absolute certainty, on anything.

Ban the Nike Vaporfly & other carbon fiber devices for future performance credibility

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

The sub-2 hour marathon in 2017? Thoughts on concept

Nike's announcement that they're backing three top marathoners to break the 2 hour marathon barrier in Spring 2017, is the latest installment in the sub-2 hype. Relevance and legitimacy aside, what would it take, product and course wise, to achieve? I look at shoes and downhill running to illustrate the concept of physiological barriers and how they might be shifted.

2016 publications: From the armchair to the site, via these journals

Much of what you read here on this site is my attempt to translate the research I'm interested in, and which can be applied to the real world, in a way that makes it more "palatable" to you. This post, however, summarizes some of the "source" research, the scientific articles that I've had published in the last 12 months, for those wanting to see the academic side of the discussions we have.
