Online pre-registration for the festival will close June 16 at midnight.

Start times

All events will have individual pre-assigned start times. Lists will be added as they become available.


Will be posted as they become available.

Timing system

We will use the SPORTident electronic timing and punching system for all events. All competitors are required to use an SI-Card to participate. If you don’t own your own, sign up to rent one when you register ($3/event or $15 for the entire festival). Contactless (Air+) punching may be used for some events: check event pages.


If the SI unit fails (you don’t hear a beep or see a flash), use the manual pin punch to punch your map.
