Mad Marathon, Mad Half & Relays

Mad Marathon, Mad Half & Relays is held on July 11, 2027, in Waitsfield, Vermont. Four distances start together at 7:00 a.m. — the marathon (26.2 mi), the half marathon (13.1 mi), a 10K (6.2 mi) and a 5K (3.1 mi) — with relay teams running the marathon distance. No elevation gain is listed.

The Mad River valley is hill country, and a marathon there is a different proposition from a flat city race: expect to lose several minutes on the climbs and to take only part of it back on the descents. The relay is the sociable alternative — each leg lands in 10K territory, short enough to run hard, and the team keeps you out on the course all morning without the damage of a solo marathon.
