Men's Health did a feature a while back on a Western runner who attempted to play their games (a tag-like game) which consisted of running for a whole day and contrasted this with their lifestyle and diet which consisted of partying and corn mash. Apparently they have near immortality, low heart risk etc. http://www.menshealth.com/cda/article.do?conitem=3b4b1ca01e9... A really interesting read.

And NYMag did a feature on shoe tech (comparing Masai, Nike Free, Vivo, Vibram) before the Ferris hype: http://nymag.com/health/features/46213/index1.html, much more in-depth than the Wired article.
