> Meb Keflezghi, winner of both the Boston and New York marathon, that he's not built to run. He's a prime example of a heel striker [1], though slightly less prominent in his later years.
Trained hard and overcame the limitation for a time? I did say there are exceptions.
> More generally, in [2], a study of elite level runners in the half marathon, found that at the 15km point the top 50 was comprised of 62% rear-foot strikers, 36% mid-foot, and 2.0% fore-foot strikers.
Reflects that heel-strikers are more common.
From a quick search:
1,991 runners were classified by foot-strike pattern, revealing a heel-strike prevalence of 93.67% (n=1,865). A significant difference between foot-strike classification and performance was found using a Kruskal-Wallis test (p < 0.0001), with more elite performers being less likely to heel-strike.
