If you were running the Boston Marathon today and looked to your left around mile marker 17, you'd see a famous face in the crowd! Dierks Bentley is cheering on the runners as they compete in the country's oldest marathon!

We don't know what he's wearing or if he's still there, but this video from Facebook sure looks like Dierks is in among the crowd and soaking up the Marathon atmosphere!

Congrats to Meb Keflezighi, by the way, for being the first American male athlete to win the Boston Marathon in thirty years, and to Kenya's Rita Jeptoo for winning the women's race and beating the 12-year-old course record in the process.
