Conditions are expected to be really good for Sunday's London Marathon (much better than in Boston), and as a result Felix Limo says he'll need eyes on the back of his head.
Once again London has attracted an incredibly deep field and features some of the best talent ever outside of the Olympics.

Interestingly, Khannouchi, who has battled injuries for the last few years, has downplayed his chances saying he's 90 to 95 percent after foot surgery. He said the same types of things last year and ran 2:07, which was the fourth-best time by an American and the best by an American in 2006 by nearly two minutes.
