Molly Huddle became the fastest American woman ever at the 13.1-mile distance on Sunday, setting the American record of 1:07:25 at the Houston Half Marathon.

Averaging 5:08 per mile to run to a seventh-place finish, she was 9 seconds faster than Deena Kastor, who held the previous record, was in 2006. On the way to that history-making mark, Huddle, 33, also set national road records for 10 miles (50:52) and 20K (1:03:48).
