Despite rainy and windy conditions at Monday's Boston Marathon, American Desiree Linden churned out almost even splits from Hopkinton to Copley Square. Her consistent pace is all the more impressive when you factor in the course's steep initial descent followed by rolling hills in the second half of the course.

On her way to a 2:25:39 overall finish, Linden ran 1:12:45 for her first half and 1:12:54 for the second. In comparison, Shalane Flanagan, who stuck with the lead pack through 13.1 miles, faded on the Newton hills and ran more than two minutes slower for her second half marathon. She finished in 2:27:47.

Here's a breakdown of Linden's 5K splits.
