Excuse me, but I call bullshit.
Taken from the KLAS Channel 8 website:
A runner from Russia, Sylvia Skvortsova, won the Las Vegas Marathon 2007 with an unofficial finishing time of 2:29:02. The top men's finisher is Christopher Chebobibich from Kenya, who will take home $20,000. His unofficial finishing time was 2:16:49. The women are given an 18 minute lead in the race and this is the first time a woman has won the challenge.
How can someone WIN a marathon if she doesn't have the best time?
I'm not knocking Sylvia's accomplishment, which is remarkable, but just because she was the first person over the finish line doesn't make her the winner.
