Join us again on June 7th, 2025 for the second running of the Huron 100 Endurance Run and Waterloo-Pinckney 50 miler! Both of these races take you on an epic point-to-point adventure across the Huron River Watershed. The Huron 100 will take you on an unforgettable journey through 6 State Recreation areas, 2 Metroparks and 1 County Park. It is comprised of 80% trail and has roughly 8000 feet of elevation. There will be 14 aid stations (including 5 crew access aid stations) along the course with a 32 hour cut off. If the 100 miler is too much to bite off this year, we are also offering a 50 mile option: The Waterloo-Pinckney 50 or WP 50. It is also a point-to-point race and is comprised of 83% trail and has roughly 4300 ft of elevation. The WP 50 will start prior to the Huron 100 and will take runners on the ultimate odyssey through the Waterloo-Pinckney area. There will be 8 aid stations (including 2 crew access aid stations - new this year) along the course with a 15 hour cut off. A 9:00 AM start time for the Huron 100 will allow you plenty of sleep and prep time prior to catching the morning shuttle to the start line at Waterloo State Recreation area. The WP 50 will start at 7:00 AM this year to allow runners plenty of time to finish before sunset.
