Huron 100

The Huron 100 is a point-to-point endurance race covering 100 miles through the Huron River Watershed in Southeast Michigan. The course starts at Waterloo State Recreation Area near Grass Lake and finishes at Proud Lake Recreation Area, crossing 9 regional parks, including the Waterloo-Pinckney Trail, Huron Meadows, and Proud Lake. About 80% of the surface is trail, with roughly 8000 feet of cumulative elevation gain.

A 50-mile option, the Waterloo-Pinckney 50, is also offered (about 4300 ft gain). The event features 15 aid stations (8 crew-access), 32-hour and 15-hour cutoffs, a strong volunteer culture, and proceeds that support the watershed. Visit the organization's website for the most recent information.
