Cancer Active proudly presents the 4th Annual Not-A-Sprint Ultra Races, an endurance event that welcomes all — from elite ultra runners chasing 50+ miles to walkers soaking in the spirit of community and purpose. Whether you’re pushing for a PR or pacing yourself through your first endurance challenge, this event is Not-A-Sprint.
Held on the scenic and flat Thermal Belt Rail Trail, this 8.34-mile out-and-back paved course starts and finishes at the Pavilion on Park Square (POPS) in Forest City. Aid stations are well-stocked, the course is low on elevation (only 95 ft over the entire loop!), and shade covers about 35% of the route to help with end of Summer heat.
Experienced ultrarunners: Test your endurance with a shot at 50 miles or more. Complete 6 laps (50.1 miles) in 12 hours and earn a custom "Not-A-Sprint" belt buckle. Set a new course record and win $250! (Current record: 66.72 miles by Kelly Woodard)
New or recovering athletes: Walk, jog, or run your race — this course is flat, shaded, well-supported, and welcoming. You choose the pace and the challenge.
