Cross Country Ski and Fat Bike Race for individuals and relay teams over a 24-hour period. A half-24 option is available. The course will be stocked with aid stations and snow making is available on 6 km of the route.

A note from the event organizer: “The 2021 24 Hours of Wirth is currently on hold and registration is not open at this time. We are working hard to come up with a solution, but at this time it seems unlikely that we will be able to conduct this event due in large part to the need to provide participants with food and housing accommodations during a time when The Trailhead is closed to general use (including event participants).”
