salazar's talking 12:37 for mo, so I'm not thinking Gebremeskel's going to be the favorite at any pace. Rupp now has the ability to win at either distance and don't forget that he closed a 13:20ish race at trials in 51.5, faster than the Olympics.
I hope Rupp and Farrah's training isn't effected too much by their thyroid disorders.
Based on what? Rupp hasn't even raced a 5k or 10k yet, has he?
based on world leading times in every 3 different events
