Northwoods Winter Marathon & Half Marathon Championships Duluth, MN   Jan 3, 2026

The Northwoods Winter Marathon and Half Marathon Championships will run on the great fat bike trails in Lester Park. We’ll also utilize the spectacular Hawks Ridge fat bike trail, perched high above the Lakeside neighborhood with tremendous views of the City and Lake beyond! There will be “no shoe” and snowshoe divisions.

The Duluth Winter Trailrunning Series (DWTS) is a series of fun, challenging and unique trail running races taking place primarily on the wonderful snowpacked fat bike multi-use trails in Duluth, MN. The trail running series will take advantage of the extensive system of packed multi-use fat bike trails that snake throughout the City of Duluth and provide incredible and unique opportunities for trail runners to explore the amazing topography and views of Duluth in the winter. Locals find the packed fat bike trails to be even more fun to run in the winter than when they’re snow free!
