Olympian Flanagan wins Rock 'n' Roll half marathon

SAN DIEGO (AP) U.S. Olympian Shalane Flanagan won the women's half marathon in 1:07:51 at the Rock `n' Roll Marathon on Sunday, breaking her personal best by 40 seconds.

It was the second-fastest half marathon by an American this year, behind Molly Huddle's 1:07:41 at the NYC Half in March.

Amy Cragg, who beat Flanagan at the U.S. Olympic Trials marathon in February, finished two minutes behind Flanagan on Sunday, but still ran a personal-best 1:09:51.

Rock `n' Roll San Diego will be their only race prior to the Olympic marathon in August.

Eric Noel of San Luis Obispo won the men's marathon in 2:26:40 while McKale Davis of Chandler, Arizona, won the women's marathon in 2:56:16.
