Move for MDS: Boston

Move for MDS: Boston is held in Boston, Massachusetts, on October 25, 2026. One distance is scheduled, a 5K covering 3.1 miles, and it starts at 9:30 a.m.

Boston in late October gives you the cool, dry air that makes 5K pace feel a little more manageable than it did all summer, and a 9:30 start leaves room for breakfast and an unhurried warm-up. If you want a fast time, the last four to six weeks matter most: one weekly session of mile repeats or 800s at 5K effort, an easy long run to hold the aerobic base, and two calm days before the race. If you are running it to take part rather than to compete, start conservatively and let the final mile be the one you remember. Recovery takes only a few days, so it fits neatly into a longer fall plan.
