According to Kenyan runner Felix Limo (London and Chicago marathon winner) American distance runners have been surpassed by Africans because "U.S. runners rely too much on structure and scientific programs". Other sources quoted in the article say Americans don't have the same threshold for pain as the Africans and, oddly, Americans have read too many books and have become too structured in their training.
If I didn't know anything about the sport and its literature I might be so inclined to buy this argument hook-line-and-sinker. True, there is a plethora of science and literature that has entered the sport in the last couple of decades. But too much reading? Too much structure? I don’t think so. First of all the literature the article sites as influencing American elite runners would lead one to believe the author is, well, clueless. He points to Runner’s World Magazine, a magazine designed for beginning runners, as an influence. Runners World? Come on Wall Street Journal, do you think our elites have been sitting around waiting for there monthly issue to learn the top 5 ways to improve their 5k time? Another source sited is the Runners Handbook, by Bob Glover. While he writes good training primers for beginning to advanced runners, Glover's books fall way short of elite training tools. A reference to Jack Daniels or David Costill would’ve lent some credibility.
