Heat+Distance=Record?

It is well documented that as the temperature around an endurance athlete increases, performance decreases. And while one can train for and adapt to warm race conditions to mitigate that decrease, the effect remains. But at the highest levels of competition, control of the mind may make all the difference.

Given the conditions, conventional wisdom would dictate a cautious pace for the Olympic men's marathon, but that's not the way it played out. With temperatures in the 28-29C range by mid-race (mid 80s F), the pace was termed "suicidal", with a 1:02:37 half split. I expected the lead pack to wither at 18-20 miles, but that's not what happened at all. Ultimately, Sammy Wanjiru of Kenya prevailed in 2:06:32, smashing the Olympic record by nearly three minutes, and giving Kenya its first men's marathon gold. Perhaps more amazing is that the run was only two minutes shy of Haile Gebrselassie's world best run last year at the Berlin Marathon under far superior conditions. One can only imagine what Wanjiru might be capable of in the years to come.

So Greg has made it clear that he doesn't think that there's any genetic basis for why some groups of people are able run very far, very fast. At the core of this are so-called "racial traits". Any casual observer of the Olympics will note the dominance of people with dark skin in distance running…

Yeah, when I saw them turning in 4:44 miles in that heat & humidity, I assumed there was no way they could keep up that pace.

I am disappointed that you haven't at least commented on the fact of how many of the high finishers in all (a lot? I don't have complete results) of the races longer than 400M were from one small region of the planet: E Africa - Kenya, Ethiopia, Eritrea. Is there evidence for genetics, environment, culture, training methodologies, or just coincidence? Does this happen so often that it is no longer noteworthy? Have there been other discussions about this that you can point me to? Or, is this a taboo subject? Or, am I seeing something that isn't really there?

Funny you should mention that Karl as I was thinking of posting something in response to a recent entry on Greg Laden's Blog.

The dominance of athletes that come from the horn of Africa in distance running is real. Why it is, I'm not sure, but I can say that I don't agree with the major thrust of GL's post.
