With the warm weather seen this October it’s hard to picture the cold winter for the John Beargrease Sled Dog Marathon. The Beargrease Fur-K, is the largest fundraiser for the event. People across the greater Duluth area could either run, walk or even bike in the Fur-K. Mike Keyport is a descendent of John Beargrease.
