24 Hours of Wirth Winter

Cross Country Ski & Fat Bike
Individual & Relay

COVID-19 Update: 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).

This ultra-marathon cross-country ski/fat-tire bike event is equal parts grueling athletic feat and fun outdoors experience. As a celebration of the approaching Spring Equinox, 24 Hours of Wirth and the 12 Hours of Wirth begin and end with the sun. The 24 hour will begin at sundown on February 28, or 5:59pm. The 12 hour will begin with sunrise on the February 29, at 6:52am. Both races will end at sunset on Saturday evening, at 6:00pm.

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 needing to ski or bike for 11 hours and 8 minutes.

Compete either as an individual or as part of a relay team. All skiers and fat bikers will be supported with a fully stocked aid station and will find sustenance, comfort, and community in The Trailhead throughout the night and day.

Registration and transaction fees are non-refundable, including in the event of delay, rescheduling, or cancellation of an event or program. An event or program registration is not transferable to another person or another event for any reason, including injury. Participating under another person's name will result in disqualification.

A Note About the Data We Collect

Note about day-of registration: We will have limited day-of registrations available for both the 24-hour and 12-hour events. These will be available on a first-come, first-serve basis. If you are certain you want to do the event, please register online prior to 5:00pm Friday to make sure you are able to participate. If we run out of available slots prior to your arrival at the race and you have not yet registered, you will not be able to participate.

Note about race bibs and timing chips: Ski bibs and timing chips must be returned by the end of the event. Failure to return these items will result in charges of $20 per bib and $150 per chip, invoiced the week after the race. Bike plates are disposable and do not need to be returned.

Timing and Relay Teams

Gather your friends and put together a relay team! Relay teams can register up to four people per team.

Both the 12 and 24 hour races will be timed using ankle chips. Results will be based on distance completed prior to sunset at 6pm, with the tie breaker being the time of completion of that final lap (believe it or not this happened last year, a distance tie after 24 hours…).

Each team will have a single ankle chip that will need to be exchanged between team members. Your team then gets to decide how often you want to rotate racers.

Bikers and skiers may join forces on a relay team, but they will not be eligible for awards.

A screen in The Trailhead will track live results.

Aid Stations

A basic aid station will be set up at the lap/relay tag zone, just outside the Trailhead. It will have water and Tailwind energy drink as well as some simple snacks.

Inside the trailhead we will have a fully stocked ultra style aid station. Think sweet and salty snacks, sandwiches, soups, pancakes and more.

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

Support + Volunteership

24 Hours of Wirth will be no cakewalk. Competitors must be prepared to take care of themselves while they are on the trail.

But racers will 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.

More than other Loppet Foundation events, the Loppet Ultras, 24 Hours of Wirth included, is a community effort, and depends on racers helping us recruit the volunteers that make the event possible.

Answers to FAQs

Are there waxing recommendations, and where can I wax? We are not putting out recommendations. You may bring a waxing stand and set it up on the Trailhead’s north patio. Boulder Nordic Sport may also be able to help with recommendations and waxing throughout the day.

Will there be a microwave at the aid station? Yes, there will be a microwave and a water heater at the aid station.

Do youth participants need to be accompanied by an adult? Yes, participants under age 18 need to be accompanied by a supervising adult 23 years old or older (need not be a legal guardian).

Awards will be given to the top male and female bikers and skiers, as well as to the top open (i.e all male or mixed) and all-female teams in both disciplines. Bikers and skiers may join forces on a relay team, but they will not be eligible for awards.
