You are delusional, or at best willfully ignorant. Trying to talk down the WS course record because of conditions is just stupid, and you know darn well that he set the 50 mile record prior to getting beat by "that Japanese runner". Which he did, by the way, in less-than-ideal conditions.
It is some hype, sure, but not all. Nobody is saying he is the best runner ever to lace up a a pair of shoes, but your unwillingness to even acknowledge his level of talent says more about you than anything else.
