If you haven’t tried endurance snow sports yet, you’re missing a chance for some serious winter suffering, err, scenery. If cold weather isn’t your thing, we promise you’ll get warm fast, and have a heck of a lot more fun then running like a hamster in the gym. Some of these races require snowshoes, others skis and some just plain old running shoes.

Race the Divide
February 26 • Monarch Mountain
Rumor has it that this Salida SkiMo race is adding more tree skiing and boot pack to the course this year. This is a great first ski mountaineering race experience as categories are small (only two women entered the Ladies’ Rec category last year) and everyone is really supportive. Enter the Race category and complete four laps and 3,500 feet of vertical, or the Rec category for two laps and 1,500 vert.
