Rock CF Rivers Half Marathon

Registration

The Rock CF Rivers Half Marathon is set to take place on March 9, 2025, in Grosse Ile, Michigan. This annual event, now in its 14th year, features a half marathon, a 5K run/walk, and a virtual run option, encouraging participants to help raise awareness and funds to combat cystic fibrosis. The event promotes community involvement, with 100% of proceeds supporting the Rock CF Foundation's mission.

Participants can enjoy a scenic route around Grosse Ile while contributing to a meaningful cause. Registration is available online, and there are opportunities for volunteering as well. Visit the organization's website for the most recent information.

Always double-check with the organizer's website – things can change, and we might have sprinted past a few details!
