Fascinating article on how weight correlates to speed. But how lean is lean enough?
At every level of the sport, leanness is as important as aerobic capacity, speed, and running economy. And even at the elite level, it seems, some runners could get faster by getting leaner. A good case in point is Chris Solinsky, who made a quantum leap in performance a few years back when he set the then American record for 10,000m (26:59.60, which has since been bettered by Galen Rupp) and lowered his 5000m PR from 13:18.41 to 12:55.53. That leap coincided with a visible leaning out that was widely commented on at the time. While it’s impossible to separate the direct effect of Solinsky’s fat loss from those of the training that contributed to the fat loss on his performance, I think it’s reasonable to speculate that the fat loss did have a direct effect.
