In 1990, the Copper Basin 300 Sled Dog Race (CB300) was founded in Glennallen, Alaska with the purpose of supporting local businesses in the slow winter months. Thirty-four years later and the race still brings excitement to town during what feels like the slowest and coldest part of winter. The race is held annually in the Copper River Valley region. It is an iconic mid-distance Iditarod qualifier and is known for its challenging terrain, stunning scenery, and competitive field of mushers and dog teams.

During this year’s race, Ahtna’s Land Department partnered with Ahtna Intertribal Resource Commission (AITRC) and the Bureau of Land Management (BLM) Glennallen Field Office team to operate what is known as the Sourdough Checkpoint. This designated location along the race route plays a critical role in facilitating the well-being of mushers and their dogs, as well as race documentation and progress checks.

Across all three agencies, staff came out to volunteer for set-up, operations, and closing the Sourdough Checkpoint. Throughout the race, the team provided essential support to the mushers and canine athletes.

Race officials and veterinarians from around the state were among the other volunteers this checkpoint housed to provide critical care and support to all competitors. Last but not least, the Sourdough Checkpoint provided a wonderful location for local families and other spectators to enjoy and cheer on arriving and departing race teams.

Volunteers shared inter-agency relationship building and a strong sense that they were a part of something that brings a lot of value to their community. The Ahtna Land Department looks forward to this race each year and hopes to continue to be a part of an event that preserves the heritage of mushing in Alaska and truly captures the spirit of adventure.

The Copper Basin 300 is a 100% volunteer-based race that starts in Glennallen, AK every year during the second weekend of January.
