Cancellation Policy

The River Valley Run does not allow for refunds of entry fees. However, we understand that circumstances arise so you may defer your registration or downgrade your race event:


If you would like to downgrade or upgrade races (eg- switch from the 15K to the 10K, 5K to 10K, etc...), or if you are now unable to attend and would like to transfer your registration to a friend or family member, you may do so for a $10 fee. You can do this yourself in your account up until August 10th.


If you become injured or circumstances arise that keep you from participating in the River Valley Run Trail Festival in any capacity in 2018, you may defer your entry to 2019. Deferments are for one year's use only and cannot be applied to subsequent years after that time. There is a $10 processing fee to defer. You may do this anytime before August 10th by completing the form below.
