REGISTRATION OPENS AUG 1ST, 2021
To register for the St. Croix 40 Winter Ultra, simply click the Ultra Signup banner above. You will be taken to Ultra Signup to complete the rest of the registration process.
COVID-19 UPDATE: We are assuming the race will happen, with some modifications to achieve social distancing. We will do our best to keep everyone updated if anything changes.
Registration will be capped at 110 participants. In order to maintain a good balance between bikers and foot/ski participants, we are limiting each category to the following numbers:
- Ski – 10 participants
- Foot – 50 participants
- Bike – 50 participants
There is a waitlist for each mode. In November we will transfer spots from un-filled divisions to divisions with waiting lists.
We will fill spots as they open up until the final week before the race.
There are no refunds if you cannot make the race, or do not arrive with appropriate gear. Please plan accordingly!
