Diamondback 8 hour Ultra

We will not have the race in 2026 and could use your help to see if we can hold it in 2027. We are in need of an Attorney to work with our Friends Group (Volunteer Group/Non-Profit)to develop a race waiver. We also would like a volunteer local race director who is experienced in trail/ultra running. The park has many volunteers and staff ready to work and plan the event but we need these two important pieces before proceeding. Email [email protected] if you can help in either of these capacities.

Results are now available

Race results on ultra sign up are not posting correctly for the women. We are continuing to work on it and have reached out for support. Thanks for your patience.

A quick note about the top awards. Koreshan State park has a Blacksmith and Rangers who took scrap metal and smithed diamondback rattlesnakes. Each is one of a kind and unique.

Thank you Volunteers !
