Volunteer Requirement

Since 2009 we have been requiring 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, x-c ski race, trail maintenance, coaching or officiating a school track team, river valley clean up, etc. This is a mandatory requirement and should be completed between the time period of the previous year’s Blackfoot Ultra to May 10 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 email us the information and contact information for your supervisor once your volunteer commitment is completed. 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

Changes to Race Registrations

We do allow dropping down for the 100 km and the 50 mile distances as these are big commitments. The 100 km can drop to the 50 mile or 50 km distance up to May 10th of the race year. The 50 mile can drop down to the 50 km up to May 10th of the race year. There is no refund for a downgrade in events. There are no drop down options available for the 50 km or the 25 km. If you are injured, a rollover is the only option.

Entries are NOT transferable and there are NO refunds for Blackfoot Ultra. We will however transfer your entry for the next year’s event if we are contacted before May 10 of the race year. You must have a good reason and email us pictures of why you can’t race. In 2006 one of the runners sent a picture of a tube sticking out of his ribs due to breaking a few and puncturing a lung. This passed the test. Any runner receiving a rollover will be responsible for any fee increases for the next year’s entry and can also change their entry to a longer event.
