This March "The Nature of Things" aired a good episode, "The Perfect Runner", on human adaptations to distance running, evolution, etc.. They cover everything in the article in more depth plus more, such as some possible reasons for the supremacy of Ethiopian long-distance runners. http://www.cbc.ca/natureofthings/episode/the-perfect-runner.html http://www.cbc.ca/natureofthings/episode/the-perfect-runner.... (If you're really keen, the above link includes references under "resources".) The article seems a big cribbed quite frankly in that it mostly talks about the a subset of the same things the NoT episode did, only in less detail. The man vs. horse marathon was not in the NoT though. If you are interested enough in this to watch a 40 minute documentary then the NoT episode is highly recommended. It might be difficult to find for those outside of Canada unfortunately.
