The Bolder Boulder has landed the hottest story in American distance running.

Californian Ryan Hall, who won the Olympic marathon team trials in November, has agreed to run the professional team race. Leading the U.S. women's team will be Deena Kastor, a three-time Bolder Boulder winner who captured a bronze medal in the marathon at the 2004 Olympics.

The combination of Hall and Kastor marks a major coup for the Boulder race.

Hall broke the Olympic trials record with a time of 2 hours, 9 minutes, 2 seconds in a race around New York's Central Park. He also shattered the U.S. record in the half marathon in 2007, becoming the first American to break one hour for the distance.
