Event Cancellation Policy

 Please read carefully and thank you for your understanding.  If you have any issues with these policies please do not register for our race as this policy will be strictly adhered to.

As a mountain biker, we at Ridge Riders are confident you know what it means to take risks. Much like dropping in on a steep rocky descent or committing to ride a distance outside of your comfort zone, risk is inherent in our sport. The act of registering for the Dakota Five-O event, although not quite as dangerous as riding your bike, presents risks. If an act of nature or other event beyond our control occurs, what can event participants expect?

  1. Ridge Riders 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.

  2. If the event is cancelled, participants will receive first right to sign up for the following years event via early registration.

  3. Ridge Riders 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, insurances, 3rd party vendors, administrative expenses, rental fees, and other related expenses.

  4. If the race is cancelled by the event directors the following refund and transfers guidlines is null and void. 


Please keep in mind we do not allow you to forward your entrance to the next year's race for any reason.  We also DO NOT allow you to let another rider race for you without going through the transfer process.  This poses a big liability issue for us and we ask that you respect our policies..

We have a waiting list on  If you decide to transfer your entrance, it will go to someone on our waitlist- You CAN NOT sell or give your entrance to another rider that you know. To transfer your entrance contact Kristi Jewett at

  •  Transfers/refunds will NOT be allowed after the August 10th deadline, no refunds will be issued, and no further riders will be let into the race after this date as we need to send the roster to the chip timers and move on to other race business!!! 


  • For those of you that want your race entrance fee refundable all the way up to race day, offers registration insurance when you register.  You will need to read through their policy to see if this is something you want, some restrictions do apply and you must have a valid reason with proof that you aren't able to attend the race in order to qualify for a refund.  Keep in mind, if you do not purchase the insurance through you are subject to the rules and deadlines of the Dakota Five-0 transfer/refund process!
