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 Fun Run starting and finishing in Grinnell, Iowa's Central Park. For 2025 we will continue to offer gravel riders amazing routes for 25, 50 and 100 miles and a race challenge for the 100 mile riders. Register today at https://www.bikereg.com/prairie-burn
