Welcome to the Rim To Rim Trail Run, Chico’s original ultramarathon. We're going to be taking 2017 off to recharge and regroup, so there will not be a race this year. Look for updates on Facebook, and may you run well wherever your legs take you!

Thank you to everyone came out for the 2016 Rim To Rim Trail Run! Results are available.
