Thunder Bay Thriller

Welcome to the Thunder Bay Thriller!

Take on the challenge of the 62-mile multi-surface gravel grinder through the scenic Northeast Michigan countryside and trail system on September 14th, 2025. We are excited to announce that we will be part of the Michigan Gravel Race Series for the upcoming 2025 race calendar!

This fun and challenging route will take riders from rolling gravel backroads onto exciting snowmobile two-track against the picturesque Devils Lake, then weave through the woods of the Norway Ridge Pathway single/two-track system before cranking down the Alpena-Hillman Trail.

Want to ride but looking for something a bit shorter? We’ll have the 27-mile option as well as the NEW 16-mile option to race day. The 27-mile course will still take you along all the fun of Indian Reserve Rd, Devil’s Lake, and the Norway Ridge Pathway.
