Rock CF is hitting the island for the 14th Annual Rivers Half Marathon & 5K Run/Walk on Sunday, March 9th, 2025 for all to come and help us outrun cystic fibrosis!
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. 100% of all proceeds support the mission of the Rock CF Foundation.
The Memorial Day 5k Race, a longstanding favorite on the island, is back! Previously hosted by the Island Road Runners, the event is now under the care of Conz Productions—but don’t worry, the race you know and love remains largely unchanged. Runners can still choose between the 5k and 8k routes, while kids can enjoy a free, one-mile fun run (note: T-shirt and medal not included for the fun run). The race will kick off on May 26th at Grosse Ile High School.
Registration Details:
5k: $40 until May 1st, after then $45 until race day
8k: $45 until May 1st, after then $50 until race day
Register by May 1st to guarantee your race T-shirt! Registrations after this date will still receive a medal, but T-shirts will no longer be available.
Please note: Participants who register within 5 days of the race are not guaranteed a medal, so sign up early to secure yours!
