Event Cancellation Policy
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. In 18 years of putting on bike races, we have never had to cancel an event.  If however, 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, 3rd party vendors, administrative expenses, rental fees, and other related expenses.

  4. All prize money will also be forwarded to the next year's race (so prize money the following year will be double).


Please keep in mind there are NO REFUNDS, for injuries or anything else that may prevent you from riding the race!!  We also do not allow you to forward your entrance to the next year's race for any reason.  And on a final note, we 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.  Thank you for your understanding, and if you have any issues with these policies please do not register for our race.

  • Registration transfers will be allowed until June 31st with a $25 transfer fee, and from July 1st to July 31st  with a $35 transfer fee, and from August 1st to August 15th with a $50 Transfer fee.  Transfers will NOT be allowed after the August 15th deadline, 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!!!  We have a waiting list on bikereg.com.  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 kj@kristijewett.com


  • For those of you that want your race entrance fee refundable all the way up to race day, bikereg.com offers registration insurance for an extra $16.  You will need to read through their policy to see if this is something you want, some restrictions do apply.  Keep in mind, if you do not purchase the insurance through bikereg.com you are subject to the rules and deadlines of the Dakota Five-0 transfer/refund process!

  • Registration will close upon reaching 800 participants.  After this number is reached, spots will only be available for sponsors, past volunteers, and other VIPs.   **Volunteers will be given a guaranteed spot in the next year's race.  If you volunteered the previous year,  you must contact Kristi Jewett before the August 15th deadline to recieve a spot in the race.  Volunteering consists of trail work, marking and tear down of race course, and day of race  help at aid stations and road crossings.  To volunteer for this year's race, please contact Kristi Jewett at kj@kristijewett.com
