BOSTON (AP) — The women's race has begun at the Boston marathon.
Americans Shalane Flanagan and Kara Goucher were at the front for the elite women's start. They are trying to be the first U.S. winner at the world's oldest annual marathon since 1985.
The men's field is scheduled to go off 28 minutes later, at 10 a.m.
The temperature was 48 degrees with a few clouds in the sky, perfect conditions for the 117th running of the race. Temperatures were expected to reach the mid-50s.
That's a lot different than last year, when temperatures spiked toward 90 and organizers offered an unprecedented deferment into the 2013 race.
