Say anything you want, but it was the heat that caused cramping.
Too bad he could not afford moving to LA for a couple of months
for adaptation and training on the course. No extra layers of clothing
or anything indoor can substitute for that. We all heard the stories,
yes, including the one about that Alaska woman who won LA marathon, etc
but that's more of an exception. Running in direct sun for two hours is very
tough, even in cooler temps.
