Susitna 100 and Little Su 50K

The Susitna 100 is a ski, foot, or bike race held on packed snowmachine and dog sled trails in the Susitna River valley, north of Anchorage. The remoteness of the trail, distance between checkpoints, and the winter conditions during the Race make it necessary for the racers to carry with them survival equipment. Gear to be used must pass inspection.

Run in conjunction with it’s older brother, the Susitna 100, the Little Su 50k shares some of the same course as the 100 miler. This race offers a distance that will appeal to the sprinters as well as those looking for a day adventure. It will also appeal to those who are here to watch and/or support someone doing the longer 100 mile race.
