Volunteer for this event

Diablo Trails Challenge 2019
50K, 1/2 Marathon, 10K, 5K


A volunteer is one who comes out to our race and volunteers their time (usually 4-6 hours) helping our runners (usually at an aid station). One cannot volunteer and run the race the same day as it isn't physically possible! After one volunteers their time helping out, we then offer a future complimentary race entry (of half marathon or less) as a thank you for helping out. We also offer a race shirt and snacks at the race too. If we have extra finisher medals, we offer those for any volunteer who would like one.
