Cancellation Policy
The act of registering for the Dakota Five-O event presents risks. If an act of nature or other event beyond our control occurs and we have to cancel the race, what can event participants expect?

Event director decisions will be based on participant safety & environmental impact. Often times these decisions are in the hands of the land owners or agencies our events are permitted through.
Event directors cannot accept the risk of a cancelled event for reasons beyond our control. Participants are respectfully requested to accept the financial risk of their individual entry and understand that you will not be refunded any portion of your entrance fee if the race is cancelled. This is due to the fact that our fees have already been payed for all supplies and services associated with the event. These include permits, insurance, third party vendors, administrative expenses, rental fees, awards, aid station supplies, and other related expenses.
If the event is cancelled, participants will receive first right to sign up for the following years event via early registration.
If the race is cancelled the refund and transfer guidelines above are null and void.
