Race Schedule:

  • Packet Pickup: 5:00 am until the start of each race
  • 50 mile start: 6:00 am
  • 50k start: 8:00 am
  • 25k start: 9:00 am
  • 10k start: 10:00 am
  • Cut-off time for all races: 8:00 pm


The course: The courses for the Winter Challenge consist of a 10k loop and a 25k loop of mostly single track trail. 50k runners do the 25k loop twice. 50 mile runners start by running a 5k loop and then do the 25k loop three times. Click here for more information and course maps.

Aid Stations:
The aid stations will be between 2 and 4 miles apart. There will be one aid station on the 10k course and three on the 25k course. You will pass the first one on the 25k course twice. There will also be an aid station at the start/finish.

All aid stations will serve water, Gatorade, a variety of sweet and salty snacks, and fruit. The first and third aid stations will also serve soup, sandwiches, and potatoes. We will not be providing gels at the aid stations, so if you use gels, we recommend you bring your own favorite flavor.

There will be a place for drop bags at the start/finish aid station.

Pacers: 50k runners are allowed to have pacers on the second 25k lap, and 50 mile runners may have pacers on the second and third 25k laps. There will be a waiver at the registration table for pacers to sign. Pacers are welcome to aid station food. To avoid confusion with the timing we ask is that pacers step off the course before the finish line.


Post-race chili cook-off: Continuing the tradition of the Winter Challenge we will be hosting a chili cook-off in the lodge. If you would like to contribute a chili, click here for details!

Awards: Also continuing with Winter Challenge tradition, the finishers’ award is a snow globe.
There will also be awards for top 3 overall male and female, awards for male and female masters, and age group awards.

Lodging: We recommend staying in one of the rustic cabins or bunk houses at the start/finish area. The cabins and bunk houses are rustic but well-maintained and heated. (The bath house is not open during the winter, but there are vault toilets.) You can rent a single bunk or rent a cabin with 4 or 5 beds. We take care of renting out the cabins, so sign up for lodging on the online registration.

Parking will be at the Long Lake Outdoor Center in the main lot and in the event field. Auxiliary parking will be available just East of the Outdoor Center at the Winter Sports Parking Area. As always we recommend carpooling to make the best use of limited parking.
