Registration Info:
**Volunteer Requirement:
Since 2009 we have required racers to give back by committing to four hours of volunteer time in your local area. This can encompass anything from volunteering at a running race, triathlon, xc ski race, trail maintenance, coaching or officiating a school track team, river valley clean up, etc.
This is a mandatory requirement and must be completed between the time period of the previous year’s Blackfoot Ultra and April 30, 11:59 pm of the year of the current race. If you are planning to complete your volunteer requirement after you register for the race, please put a note in your registration details of when & where you’re planning to volunteer. You can then add the information and contact information for your supervisor once your volunteer commitment is completed to the Volunteer Requirement Form. Racers who do not provide volunteer hours will have their entry forfeited and their race fee donated to the Friends of the Blackfoot. If you have questions please email us at info@blackfootultra.com.
Changes to Race Registrations:
1. We allow dropping down for the ultra distances. Dropdowns must be requested by May 10, 2025. After this date
The 100 km can drop to the 50 mile, 50 km or 25 km.
The 50 mile can drop down to the 50 km or 25 km.
The 50 km can drop down to the 25 km.
There is no refund for a dropdown in events.
There is no drop down option available for the 25 km.
2. Entries are NOT transferable. This is for your health and safety as we need to know demographics and emergency contact information for each racer. Any racer who is caught racing under another racer’s bib will be removed from the race and both the racer and the original registrant are no longer eligible to run Blackfoot Ultra.
3. We no longer complete roll overs for injuries or changes in work schedules, etc. A 75% refund is available if the racer emails the race before Mar. 1, 2026. After Mar. 1, 2025 there are NO refunds for Blackfoot Ultra. Exception for expectant Moms. Please email us if you are pregnant and cannot race.
