The 24 and the Half-24

As a celebration of the Spring Equinox, 24 Hours of Wirth and the Half-24 begin and end with the sun. The 24 will begin at sundown on March 15, or 7:19pm. The half-24 will begin with sunrise on the March 16, at 7:24am. Both races will end at sunset on Saturday evening, at 7:20pm.

This does indeed mean that the 24 Hours of Wirth competitors will actually be putting in 24 hours and 1 minute, while our Half-24 racers will catch a break, only have to ski or bike for 11 hours and 56 minutes.

Individuals and Teams

Participants may register either as an individual, as part of a team of two, or part of a team of four. Team race category options include single-sex and mixed FM or FFMM. In summation then, the eight possible race categories for skiing and fat biking are F, M, FF, MM, FM, FFFF, MMMM, FFMM. Please Note: Due to scoring constraints mixed bike/ski teams WILL NOT be eligible for awards, but will receive information about their lap/race time.


24 Hours of Wirth takes place on a roughly 6k loop of the Theodore Wirth snow making trails, meaning that despite a historical average high/low of 42°/25° we anticipate solid conditions. Please note that the loop will include portions of the snow making trails that are not lighted (Twin Lakes and Green Meadow Trails). We encourage you to bring a headlamp for these sections!


24 Hours of Wirth will be no cakewalk. Competitiors must be prepared to take care of themselves while they are on the trail. But the racers are not be entirely alone, knowing that every time they pass by the Trailhead they will be greeted by volunteers at a fully stocked aid station (think wraps + soups).

While not racing, relay team members can take shelter in the Theo Wirth Trailhead. There will be both an area for sleeping for those who bring thier pads and bags, and entertainment for those who want to stay up through the night.


Awards are given to the top three competitors in each race category. While no age category awards are given out, racers are continually encouraged by intermittent participation based awards.

Parking and Transportation

There are no transportation restrictions during 24 Hours of Wirth. Overnight parking passes are given out in registration packets and must be displayed on dashboards of cars parked in Minneapolis Park parking lots.

The Loppet encourages alternate transportation. Biking to Wirth Park is easily accessible via city bike paths. Bus line #7 comes right to the park on Plymouth Ave
