> "Many theories are offered up as the secret to Kenya's success in long distance running, but one of the most commonly cited, especially by Kenyans themselves, is the hard, active life the children here lead. Most run long distances to school each morning, and when they get home they are sent out to tend to the goats or sheep. There are few televisions, let alone PlayStations or Xboxes."
It's definitely true that the marathon is somewhat less accessible than short or mid-distance running, but it doesn't take years of marathon running to be a top marathoner. Much of the fitness transfers from mid-distances. Many competitive 10k runners post elite times in their very first marathon race. This means that in practice, the marathon is very nearly as competitive as that for a middle distance race.
