Cal Crusher

Cal Crusher is held in Caledonia, Michigan, starting October 24, 2026 at 6:00 a.m. It is a timed endurance event: rather than racing a set distance, participants cover as much ground as they can within the allotted time, with flexible entry options, an aid station, restrooms on site, and awards for the top male and female finishers. The event raises money for Hope Unexpected, which supports single women facing an unplanned pregnancy through community support, counseling, life-skills classes and resources for mothers and children in the Byron Center and Grand Rapids communities.

Timed formats suit runners who want to test endurance without committing to a fixed finish line. Start slower than feels necessary, break the clock into blocks rather than thinking about the whole thing, and eat and drink on a set interval from the first hour. If you are new to the format, set a mileage goal you would be happy with and treat anything beyond it as a bonus.
