Hosted by the Valley Spokesmen Bicycle Club

After running the Mount Diablo Challenge for many years, Save Mount Diablo asked Valley Spokesmen to take over the helm in 2017.

The Valley Spokesmen are seeking to increase participation in the Mount Diablo Challenge by appealing to the broader cycling community, with an emphasis on family participation. The Valley Spokesmen intend to keep up the tradition of giving back to the community, both by donating proceeds from this event to community nonprofit organizations and through their continued encouragement of local cycling events.

Benefitting Save Mount Diablo

The Mount Diablo Challenge continues to benefit Save Mount Diablo through the support of CA Technologies and the Nathan M. Ohrbach Foundation, who have agreed to once again underwrite the cost of memberships for all Mount Diablo Challenge participants. This continued support allows Save Mount Diablo to further land conservation in the Mount Diablo area for the benefit of all.
