all in the last 10k??
He didn't run a tactical race, he was beat at the end. He looked exhausted those last few miles. I'm sure Rupp is more than 1:25 better than Ward, but in this particular race Ward probably did outstanding while Rupp just did well.
Didn't Rupp throw in a 14:26 5k from 30k-35k? That's definitely tactical and indicates less than ideal pacing for a 2:10 marathon. Unlike ward who was running optimally for himself, Rupp was racing for a podium spot.
