THE ROCK CF FOUNDATION

Rock CF is a community THOUSANDS strong changing the face of what living with Cystic Fibrosis looks like and giving those living with CF the tools to not only survive, but thrive.

Join us on August 23rd at Two Birds in Detroit to celebrate 18 years of Rock CF with a clue hunt run/walk, trivia, food, drinks, and Huddle's signature frozen custard.

The party starts at 5:00pm with a FREE clue hunt run/walk where teams of 4 will explore the Indian Village area for clue stops and participate in CF-related mini games. Following the clue hunt, we will be hosting a trivia session to put your cystic fibrosis, Rock CF, and general knowledge to the test. You might even learn an answer or two on your clue hunt!

Come for all, just the clue hunt or only trivia. For those of you who are unable to join us in-person or would rather spectate, that's totally cool. This is a free event, but we will have our 18th anniversary shirt in the shop on our registration site if you'd like to grab one.

WE ARE BACK! The Thunder Bay Thriller - Gravel Race. Take on the challenge of the 62-mile multi-surface gravel grinder cycling event through the scenic Northeast Michigan countryside and trail system on September, 14th, 2025. New in 2025, we are excited to represent the northeast as part of the Michigan Gravel Race Series!

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. 100% of proceeds go towards supporting our cystic fibrosis patient-focused programs & the mission of the Rock CF Foundation.
