15th Annual Rock CF Rivers Half Marathon & 5K

Lace up and join the charge at the 14th Annual Rock CF Rivers Half Marathon & 5K Run/Walk! On Sunday, March 9, 2025, prepare to hit the pavement on the scenic Grosse Ile for a run that's more than just medals and personal bests. Running with passion, you'll fuel the fight against cystic fibrosis alongside a community dedicated to altering perceptions of the condition. With every stride, you'll empower Rock CF Foundation’s mission, with 100% of proceeds driving the change. Whether you’re at the starting line or joining virtually, you're part of a movement where every runner's triumph is a shared victory against CF!
