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.
