Welcome to the Rim To Rim Trail Run, Chico’s original ultramarathon. Our second annual event took place in Chico, CA on June 11, 2016 and featured half marathon and marathon, as well as 50k and 50 mile ultramarathon, distances. Stay tuned for our 2017 date, when you can once again come follow the rugged trails of Upper Bidwell Park through the Sierra Nevada foothills and across Big Chico Creek canyon.

Thank you to everyone came out for the 2016 Rim To Rim Trail Run! Results are available, and check Facebook and your email for post-race announcements.
