Cyclists of Gitchee Gumee Shores (COGGS) was established in 1994 as a nonprofit 501-c3 organization dedicated to building, maintaining, and advocating for mountain bike trails in the cities of Duluth, MN and Superior, WI (the Twin Ports).


Our trail network was recognized by IMBA as a Gold Level Ride Center, one of only six on the planet. A lot of people, and a lot of hard work, helped us get here. Our trails are multi-use, free and open to everyone to use.

Our Mission

COGGS is dedicated to developing and maintaining world-class mountain biking opportunities for all in the Twin Ports.
