Save Mount Diablo Trails Challenge

April 11, 2020

Over 38 years, Save Mount Diablo’s efforts have helped expand the open space on and around Mount Diablo from 6,788 acres of open space to over 100,000 acres! With distances for everyone from those hitting the trail for the first time to experienced ultra-runners, the Diablo Trails Challenge was created to help celebrate and support these achievements. A portion of all entry fees will go to Save Mount Diablo to help them continue preserving open space and trails for all of us to enjoy.
