Cancelled Event


2020 Race Cancelled

I want to thank everyone for their interest in running Cuyamaca this year, and I appreciate your patience over the last several months. The California State Parks are not yet allowing events, and while it may be that by the time October rolls around, the run would be allowed, there would not be sufficient time for the race, volunteers, and runners to adequately prepare. So, the race is officially cancelled for 2020, but I hope we can look forward to a better situation next year. I wish you all the best in running and in life, and I hope to see you at a future event!

Update 6/11 PLEASE READ!

We are still on hold with the event this year. State Parks informed me that they will have "no events through 6/30, and will revisit at that time." I am looking at a cut-off date of 8/8 for cancelling the event should I hear no good news from the state at that time. I will send out another update as soon as I get more info from the rangers, and until then, please be patient and keep your fingers crossed!

Update 4/26 PLEASE READ!

Registration for this year's race will open on Friday, 5/1, as previously stated. All runners who register will be placed on an ordered wait list and no fees will be collected at this time. When and if state and local guidelines allow for organized events to occur in Cuyamaca Rancho State Park, runners will be notified and invited to register officially. Only at that time will runners be charged an entry fee.

Cuyamaca 100k will communicate with registered wait listers and via social media regarding any updates to the situation. At this time there is no timeline for announcements or expected dates for inviting runners to register officially, but every effort will be made to provide advance notice to the best of our ability.


Cuyamaca 100k Endurance Run is delaying the opening of registration by one month to 5/1/2020. We hope that in the upcoming weeks, more information and guidance from our parks will allow us to more confidently accept your registrations and plan for the run on 10/3 this year.

We are also waiving qualification requirements in light of so many runs around the world being cancelled with little notice.

Thank you for your support and understanding. If you have any questions please feel free to email me at

Course Description

The majority of the Cuyamaca 100k course lies within the boundaries of Cuyamaca Rancho State Park approximately one hour east of San Diego.  The course consists of three distinct loops, all of which start and end at Camp Cuyamaca off of Highway 79.  Each loop covers a different set of trails with minimal back tracking and repetition.  The first and longest loop of 31.5 miles traverses the western side of the park from south to north and approaches the summit of the park's high point, Cuyamaca Peak, at 6500'.  The second loop is 12.6 miles, and takes in the southeast corner of the park near Oakzanita Peak.  The final loop of 18.3 miles brings runners through northern section of the park, briefly leaves the park and enters Anza Borrego, and travels along the PCT overlooking spectacular desert views, before returning to Cuyamaca's northern meadows and returning south to the finish.
