Little Su 50K - event overview

The Little Su 50K is a winter, human powered trail race of 50K held on marked trails in remote, frozen Alaska. The event takes place near Big Lake, Alaska, and is organized by Alaska Winter Wilderness Races as part of the Susitna event weekend.

The race is scheduled in February; the Little Su 50K is listed for February 14th while the companion Susitna 100 is scheduled February 13 to 15. The course runs on marked routes that offer varied winter conditions and landscape views typical of the region.

Organizers publish practical race materials including course descriptions, course maps, race rules, gear information, and race results. There is a related 500 Club resource linked to the Little Su 50K information. The event is described as human powered and staged in winter wilderness settings, which can involve remote trail access and cold weather considerations.

The event materials note a land acknowledgement: the races take place on traditional lands of the Dena’ina and Ahtna Dene people, and portions of the land are owned by the Mental Health Trust Authority under permit. Revenue from permits supports the authority. Visit the organization's website for the most recent information.
