Course, aid, and rules

The Single Loop circles the Twin Mountain massif through rock outcroppings and valleys. The course is described as hilly, cold, and windy, with long stretches of thigh-deep snow, some ice, and about 2,000 feet of climbing. One unmanned basic aid station is located midway on the loop.

The Double Loop consists of two laps in the same direction. In addition to the unmanned aid station appearing twice, there is a fully stocked aid station at the halfway point (start/finish) offering warm food. To start the second loop, participants must finish the first loop in under 3 hours 30 minutes.

Snowshoes, skis, and other flotation devices are not allowed. Ski or trekking poles, traction devices (for example MicroSpikes or YakTrax), and grit are allowed. Mandatory gear checked at registration and finish includes 40 oz of fluids, 400 calories of food, a firestarter, wind coat, long pants, warm hat, gloves or mitts, an emergency whistle, a mylar emergency blanket, and a headlamp or flashlight for second-loop participants. There is no exit from the loop until the finish. Visit the organization's website for the most recent information.
