Mo and Galen really benefit from the Kenyans pushing the pace. What we don't know is how family life has impacted Galen. In the past he's trained well in relative silence and shown up when it comes. His life situation is a little different now. He could be great or terrible, especially if air quality becomes an issue.
I like how big of a tossup this race is. Except for Mo. He wins this race 95 out of 100 times.
