Watch Hannah England's interview after the 1500. There is nothing "up" with Rupp. He made finals of the 5000 and was in it until the last 2 laps. He was 4th in the 10,000.
I DO think that the 1/2 and marathon are his best events.
Big deal. The ENTIRE field was 'in it' until the last 2 laps. That happens in a slow championship race.
Compared with last year's Olympic silver in the 10K and the fact he wasn't much of a factor at all in either the WC 5 or 10K, seems like something MIGHT be "up".
Could just be the hard indoor season he had. Doesn't seem like Alberto would make a mistake like that though.
