Cal Crusher 2026

Cal Crusher 2026 is a 30 hour endurance run taking place October 24 to October 25, 2026 in Caledonia, Michigan. The event begins and ends near the pavilion of the Caledonia Community Green Space and uses a fixed loop course.

Participants have 30 hours to cover as many miles as they can on a 5 mile loop that runs through Caledonia, on the trails, and around the schools. Runners may complete all miles at once, break and return, or run through the night; mileage is tracked at the aid station. Restrooms and an aid station with snacks and water or juice are available on course.

Race proceeds will go toward breast cancer research at the Van Andel Institute. Awards are planned for the male and female competitors who record the most miles in the 30 hour period.

Registration details provided by the organizer include an entry fee of $35, which covers a shirt, aid station snacks, water or juice, restroom access, and award eligibility. Registration opens August 14, 2026 and closes October 23, 2026. Shirts will be ordered on October 8, 2026 so entries after that date may be subject to shirt availability.
