From Race Management

Cirque du Griffith Park has been rescheduled for September 5 and 6, 2020. In the event we cannot move forward with September, entries will be rolled over to June 2021.

We have a feature on Ultra Signup where you can sign up for the race today but your credit card won't be charged. Once we know for sure that the race is a "GO", we will notify you and you can then authorize your payment.

Think of it as an RSVP for the race or a waitlist, only the race isn't full. It just holds your place in the race until we know for sure that the park will be opened and we have permits in place.

This is a "WIN WIN" because you don't have to pay anything right now and this lets us know if runners are actually interested in running on September 5/6.
