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
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 cuyamaca100k@gmail.com.  

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.
