Prairie Burn 100 Gravel Bike Ride and Fun Run
The Prairie Burn 100 is about staying active and enjoying the great outdoors with a one-day event on the second June of each year with gravel rides and a 5K Fun Run starting and finishing in Grinnell, Iowa's Central Park. The 2024 gravel ride event offered cyclists new 25, 50 and 100 mile routes and a race challenge for the 100 mile riders. All riders were invited to test their skills in the Burner Challenge segment dash for cash on each of the loops. Along with other family-friendly activities, the 5K Fun Run provides a nice Saturday morning option to race or pace yourself for a healthy way to get moving! For more information on the 2025 event, follow Prairie Burn 100 on Facebook & Instagram or sign up for our emails.
