The CopperDog 150 Sled Dog Race is the culminating "triple crown" of Lake Superior sled dog racing (Beargrease, UP 200, CopperDog 150) beginning in Calumet and running north with a layover in Eagle Harbor and a stage rest in Copper Harbor.
Races usually run the first weekend in March. The CopperDog 150 features teams of ten dogs and covers 150 miles in three days, while the CopperDog 40 features teams of six dogs and covers approximately forty miles in one day. The CopperDog 150 caps at thirty teams and the CopperDog 40 caps at fifteen teams. Which means … the first weekend in March finds 350+ dogs racing through Michigan’s Keweenaw Peninsula.
