Course and race details

The course is a 10k loop that runs up and down the ski slopes. The route will not be lit; reflective flagging and lawn flags will mark the course. Headlamps are mandatory and required until 7am. Runners will have fixed time limits to complete their distances: 5 laps for the 50k and 10 laps for the 100k, with the 100k allowing a longer overall time limit and the 50k a shorter overall time limit.

Basecamp at the base of the ski hills will include a large tent with food, bathrooms and a gear area, and there will be multiple tents available for runners. The course includes notable elevation and possible natural obstacles such as low branches and fallen trees. The venue manager indicated snow may still be present near the top of the hills. Awards include finisher medals of at least 7 inches; top finishers receive additional custom prizes. Visit the organization's website for the most recent information.
