One of America's oldest 100-milers, deep in Ohio's Mohican State Forest
One of the oldest 100-mile races in the United States, the Mohican Trail 100 winds through 5,000 acres of Mohican Memorial State Forest in northeast Ohio. The course consists of multiple loops over a mix of singletrack, dirt road, and pavement — relentlessly rolling terrain without major mountain climbs but with significant cumulative elevation gain. Racing in late May means facing Ohio's notoriously unpredictable weather, from pleasant conditions to near-100°F heat with high humidity. Well-stocked aid stations approximately every five miles keep the course accessible, though the historically low finish rate reflects the challenge of covering 100 miles in Ohio summer heat. The race serves as a UTMB Index event and a qualifying race for the Western States 100.

Late May in Ohio delivers highly unpredictable race conditions. Daytime temperatures regularly reach the 80s–90s°F with high humidity; in hot years, heat indexes approaching 100°F have contributed to high DNF rates. Nights can stay warm or drop into the 30–40°F range, posing hypothermia risk for runners who get wet during daytime rain. Afternoon thunderstorms with lightning are common in Ohio spring. Most of the course runs through shaded forest, providing some relief, but exposed road sections add significant sun exposure. Runners should prepare for the full range of conditions and prioritize heat management strategies.
Late May temperatures can reach 90–100°F with high humidity. Heat stress is the primary driver of the race's historically low (~45%) finish rate.
Afternoon thunderstorms with lightning are common in Ohio in late May. Exposed road sections of the course increase risk.
Night temperatures can drop to the 30s–40s°F, creating hypothermia risk for runners who get wet during daytime rain or sweat heavily.
Ohio weather is highly unpredictable — race conditions have ranged from perfect 70°F days to near-100°F heat waves, thunderstorms, and cold nights in the same year.
