Horseneck Half & 3.5 Miler

Horseneck Half & 3.5 Miler is held on May 23, 2027, in Westport, Massachusetts. The half marathon (13.1 mi) starts at 9:00 a.m. and the 3.5-miler (5.6 km) at 9:15 a.m. Entry includes a race shirt, and half-marathon finishers receive a medal, with a meal and drinks at the finish.

A 9:00 a.m. start in late May on the south coast of Massachusetts is late enough that the sun is up and working, so treat the second half of the half marathon as the warm part of the race. The short 3.5-mile option is an unusual distance and a useful one — roughly a 5K plus a mile, long enough to hurt but short enough to run the day before or after something else.
