Where
Crested Butte
The Grin & Bear It is Crested Butte’s oldest trail challenge. Historically presented as a sprint to Green Lake and back, this classic event has evolved to offer a 25k Loop competition while still maintaining the traditional 15k race. New in 2025, we’re offering a 25k mountain bike race. The bike will be technical and difficult - a great training opportunity for the Summer Grand Traverse.
