Distance Changes
We cannot give money back if you choose to move down to a shorter distance but you can make the change right in your RunReg account. Just select Change Category and your preferred distance. If you are moving up in distance, you’ll be asked for the difference in cost. Stuck? Contact RunReg or us.

If you cannot race, you can transfer your entry to another runner and up until the deadline for online changes. Do this within your RunReg account. The transfer itself is free. You must arrange to receive full or partial payment from that person for your entry. See below for instructions on transferring.

Race Cancellation
In the case of severe weather or any other cancellation, any deferment credit amount will be at the race’s discretion based on incurred expenses. We will do everything possible to get the event in including rescheduling, but full credits/refunds are not available if it is cancelled (or rescheduled) due to significant costs we must pay in advance of the race (e.g., insurance, permits, vendor deposits, advertising, graphic design, etc.) along with hundreds of hours of planning. In the event of a thunderstorm, we will postpone the race until conditions improve. Extended severe weather or very muddy trails may result in cancellation of the event or shortening of race distances.
