Huron 100

The Huron 100 is a 100-mile point-to-point trail ultramarathon through the Huron River Watershed in Southeast Michigan. It threads nine regional parks, including the Waterloo Pinckney Trail, Huron Meadows, and Proud Lake, offering fast, well-maintained trails with varied scenery. The course is about 82% trail, with roughly 8,200 feet of cumulative elevation gain, a max elevation near 1,100 feet, and a 32-hour cutoff.

A 50-mile option (about 93% trail, 4,400 feet gain) is also offered. The race begins at Waterloo State Recreation Area near Portage Lake on June 6, 2026, and proceeds as a community-driven fundraiser for Huron River Watershed. Visit the organization's website for the most recent information.
