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 28 Below event, although not quite as dangerous as riding your bike, presents risks. In 18 years of putting on bike races, Ridge Riders have never had to cancel a race, but 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. 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, insurance, 3rd party vendors, administrative expenses, rental fees, and other related expenses.

  3. If the event is cancelled all participants will be guaranteed a paid spot in the next year's race.
