A point to point race with Wave Starts

So why wave starts?

Wave starts are what make this race possible. We start runners slowest to fastest for both the 100 and 50M events to minimize the impact to the trail and to ensure on-course support throughout each race. Aid Station cutoff times are based on this model.

Your estimated pace is critical in helping us seed you in the proper wave. Therefore it’s important that you provide as accurate a prediction of your estimated pace as possible. Please note that if you outrun our support, you risk arriving at an Aid Station without food, water and/or medical support.

We reserve the right to hold any runner that is outrunning the race support as defined by the Aid Station Open and Close times.

How to update your estimated pace

As you dial in your training, you can edit your estimated pace up until registration closes through your Ultrasignup account.
