Diablo Trails Challenge

The Diablo Trails Challenge is a running event that offers various distances, including a 50K, half marathon, 10K, and 5K, catering to participants of all skill levels. Scheduled for April 5, 2025, in Walnut Creek, California, the event aims to celebrate and support the conservation efforts of Save Mount Diablo, which has successfully preserved over 100,000 acres of open space. A portion of the registration fees will contribute to these preservation efforts, ensuring that the trails remain accessible for everyone.

Participants can also enjoy a BBQ lunch as part of the event festivities. Visit the organization's website for the most recent information.
