Challenge yourself...
You can do it!!

Mount Diablo Challenge
October 8th, 2017
Registration opens July 1st

After running the Mount Diablo Challenge for many years, Save Mount Diablo has asked Valley Spokesmen to take over the helm. We hope to maintain its competitive, challenging spirit, while making it welcoming to riders of all ages, families, and first-timers. CA Technoloies remains a major sponsor, underwriting costs and allowing Save Mount Diablo to be a beneficiary.
Prizes Awarded!
Medals will be awarded for 34 categories, including 15 age groups for men and women, fastest overall man and woman, oldest, and youngest riders. We are currently working with sponsors to provide prizes for these categories as well.

Prizes fueled by Hammer Nutrition: 1st, 2nd, and 3rd place categories in 15 age categories.
Special prizes for fastest man and woman wearing full Hammer Nutrition kit!

Exciting New Venue!
We are planning a BIG venue with beer, wine and food. Turnaround time at the top will be quicker, so that riders can enjoy the party! If you are a competitive rider, or just a weekender who wants to challenge yourself, this is the ride for you!!
