The last time an American runner won the Boston Marathon was Greg Meyer, 20 years ago. Do you think an American has a decent chance of winning the 117th Boston Marathon on Monday?

Probably not with the guys, but keep your eye on Desiree Devila, who had a really great race back in 2011. In my opinion, Desiree holds the best odds of an American female runner winning the world's oldest marathon!

By the way, 2011 was a perfect year for the men, too. Geoffrey Mutai of Kenya ran the fastest marathon in history with a time of 2 hours, 3 minutes and 2 seconds! A half million spectators are expected to cheer the runners on!
