BOSTON (AP) -- Robert Cheruiyot has won his fourth Boston Marathon, running away from the pack in a blistering unofficial time of 2 hours, 7 minutes, 47 seconds. In the women's race, Dire Tune outkicked Alevtina Biktimirova to win by 2 seconds -- the closest finish in the event's history.

Cheruiyot missed the course record he set two years ago by 33 seconds and became the fourth man to win the men's edition of the world's oldest annual 26.2-mile race. Cheruiyot and Tune each picked up $150,000
