The 27th running of the Quivering Quads Trail Race will be returning to its roots as a fall event! On Sunday, October 25th, join us for our Quivering Quads Fall Classic at Cuivre River State Park – featuring Ozark-like views, climbs, descents, and creek crossings, all through crisp air and incredible foliage.

Whether you've run with us before or this is your first time, you'll love all that QQ has to offer in the fall. Both our half marathon and 8-mile course will include all the exciting challenges you know and love, now with vibrant leaves, stunning scenery, and cooler temps for a trail race you won't forget.

Participants will receive a long sleeve shirt, a custom finisher medal, and post-race food, snacks, beer from Urban Chestnut, and other refreshments. Registration is limited to 400 participants.
