Paula Radcliffe’s world record is touchable.
Mary Keitany, 35, of Kenya, set the world record of 2:17:01 for a women’s-only race at the London Marathon. Her time is extraordinary, but how she clocked it was even more so. Keitany’s first half was a 1:06:54—a time no American woman has ever run in a half marathon by itself. She went through 30K two minutes faster than the world record for that distance and, running by herself, slowed considerably on her way to the finish, but not so much that the record wasn’t obviously hers. In other words, clocking the first 5K in 15:31 (which, if sustained for 26.2 miles, equals a 2:11 marathon) didn’t ruin her later like it would for most mere mortals.
What would her time be if she opted for more even splits, as suggested by coaches and runners around the world? Some experts pontificate that Paula Radcliffe’s world record (for a mixed-gender race, paced by men) of 2:15:25, set in 2003, could finally be threatened. Keitany didn’t fall off that 2:15 record pace until mile 21.
