RMRR hosts affordable, supported, and timed training races for runners of all abilities, designed to prepare participants for long spring races. These events help runners focus on pacing, nutrition, hydration, and overall race readiness. The races take place at the Platte River Trailhead Park in Thornton, offering an out-and-back course format. Participants can enter individual races or select a race bundle. For safety reasons, dogs and running strollers are not allowed on the courses.
