Sport Geek #74: the (nearly) two-hour marathon

Marathon world record, from Sports Geek (published 2016)

In my book, Sports Geek, I bravely (stupidly?) suggested that the two hour marathon was way out of reach. The reasoning was: we’re getting excited by current times, not looking at context. Also, we are not looking at the half marathon as proxy. As I put it:

… we aren’t learning from the past. If we extrapolated the marathon records set in the 1960s, we would have expected the two-hour mark to be broken back in 1977. Clearly, extrapolation isn’t everything.

I then looked at the half marathon as a proxy – the ratio should be around 2.1, and the half marathon world record is nowhere near 57 minutes.

A look at the half marathon record progression shows a more consistent pace of improvement. It also shows that to get to 57 minutes, we are looking at many decades, if ever.

This might simply tell us that runners don’t take the half marathon as seriously. Or, it might give us a warning sign not to expect the 2-hour marathon for many years to come.

So to the recent assault on the two-hour mark. Man, that was close. You can call it either way – as Quartz put it, even in a rigged race they failed. Or, it was a fantastic attempt to show what can be done. Regardless, it has put up for discussion the whole limits of performance issue, and may change running for ever.

Is LeBron James better in the playoffs? No, he’s always this good.

Swearing makes you stronger. Fucking brilliant.

Women coaching men.  Tough gig.

My blog revived

There’s been a hiatus of two years on this blog – too long, obviously. I won’t bore you with excuses. Just to say that the posts prior to this one are mainly about sport and statistics, whereas from now on, who knows. Sport will figure highly, of course.
