How big is a typical January Half Marathon field?
The median one finished 39 runners, across the 95 of these January Half Marathon races with published results from past editions. Most are far smaller than the big-city events people picture, which means less crowding at the start and a friendlier field, with a last recorded finisher at 3:20:03.
