Incredible runs all around today. Kipchoge, Biwott, Bekele with a fine return, and many others. And of course some that ran Boston as well. Based on that what kind of chance is Rupp legitimately going to have in Rio. We have yet to see Kipchoge race a tactical marathon... Does that sort of race still favor him. Or could a slower pace not suit him and leave him very vulnerable. There's no pacemakers at the Olympics. Predictions for the race and Rupp's finish.
