Refund Policy
Coloma River Races is a non-profit and proceeds from the race benefit Breakthrough T1D (JDRF). A 50% refund may be requested via email to community@clippedinforlife.org through January 27, 2027. Sorry, no rollovers, deferrals or exceptions.
The race will be run rain or shine. However, there are certain circumstances that are completely out of our control that may force us to cancel or reschedule if racer safety is in question. No refunds will be offered in the event of a cancellation due to natural disaster.
Switching Distances
Runners may switch race distances once, subject to availability. Please email community@clippedinforlife.org for assistance. If you are switching from a shorter distance to the 50K, you will be charged the difference based on the current 50K price. If you are switching from the 50K to a shorter distance, you welcome to but we are not able to refund the difference. In order to receive the correct distance swag, you must request to change your distance by January 27, 2027.
Transfer Policy
Runners may transfer their bib to a friend for free through February 12, 2027. After that date, transfers will not be allowed for any reason. You are responsible for finding someone to transfer your bib to, and any funds exchanged must be handled between the two of you.
To transfer your bib, log into UltraSignup and go to your Registration History page, find the event, and click the edit link next to your order. Please email us at community@clippedinforlife.org with questions.
