Pre-Entry – Enter Before the Cut-Off and Save!

Entries after this cut-off will have to be submitted at the event (starting Friday noon) at walk-up pricing. See pricing below. All race pre-entries will be confirmed via email within 1 business day of receipt at the PKC/SKUSA home office. If you do not receive an email confirmation within 24 hours, please call 951-491-0808 to confirm that your entry has been received and is in process.
