The Course

The courses for the Winter Challenge consist of a 10k loop and a 25k loop of mostly single track trail. The 10k course has 978' of elevation gain, and the 25k course has 1,388' of elevation gain. 50k runners do the 25k loop twice. 50 mile runners start by running a 5k loop and then do the 25k loop three times.

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


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.


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. Individual bunk for $30, cabin for 4 for $85, cabin for 5 for $100. All lodging prices include 2 nights, both Friday and Saturday.
