About
Old Colony Marathon and Half Marathon is held on May 28, 2027, in Springfield, Massachusetts. Both races start at 6:00 a.m.: the marathon (26.2 mi) and the half marathon (13.1 mi). No elevation gain is listed.
A 6:00 a.m. start for both distances is a deliberate choice at the end of May, when a late-morning finish in the Connecticut valley can be uncomfortably warm. Plan your breakfast around it — eating two to three hours before a six o'clock gun means a four in the morning alarm, and it is far better to rehearse that once in training than to discover on race day that your stomach disagrees.
