As a former distance runner (well, recreational marathoner), I'm looking forward to the men's 10,000 meters, just starting now.
Apart from the standard Ethiopians and Kenyans, GBR and USA have some potential medalists for a change...
[Added] Holy crap, Farah (GBR) and Rupp (USA) 1-2, followed by 2 Ethiopians. The great Bekele finished outside the medals in 4th. Mo is going to be a hero!
