Welcome to the Thunder Bay Thriller!
Take on the challenge of the multi-surface gravel grinder through the scenic Northeast Michigan countryside and trail system on September 14th, 2025. Your choice of 62, 27, or (new this year!) 16 mile courses.
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.

We recommend a minimum of at least around 38c tires for this route, and the entire course can be done with a gravel bike. There will be some fast rolling hero gravel, slightly rougher two-track, and maybe a lil' bit of (dare I say it?) sand from time to time on the back trails! Just enough for a good time. If you would rather hop on the mountain bike for more comfort on the trails, totally doable and a nice option in a few sections. For those local to the area, stop by our Local Bike Shop Sponsor, Harborside Cycle & Sport of Alpena for your bike-check and tire needs.
Riders are expected to follow the rules of the road based upon Michigan Bicycle Law.
The event is based out of Alpena, MI. Known as the Sanctuary of the Great Lakes, Alpena features plenty of opportunities and experiences for outdoor, culinary, and families against the beautiful, water-centric backdrop of Lake Huron.

For those of you unable to attend, we will be hosting a virtual rider challenge on the same day as the race! Awards for the longest rides on race day.
