Refund Policy and Public Health

REFUND POLICY: all entry fees are non-refundable. When you register for this event, you are making a non-refundable purchasing decision and must agree to this policy. You may not give or sell your number to another individual outside of the authorized transfer policy and process - if you do, this will result in disqualification and banishment from this event. This policy stays in effect whether you are injured, have an unexpected business or family emergency, illness, pregnancy, etc. Once you register, unrecoverable race course services and items are paid for for you as if you will be attending the event.

PUBLIC HEALTH: At this writing, the race is scheduled to continue, with all permitting agencies providing early-stage approval.  As events unfold, we will be in communication with the appropriate health agencies and provide additional communication with race participants via email and the various race pages.  

We will provide additional information as we get closer to each race day, but you can help us ensure the ability to produce an in-person event by following standard public health recommendations: get vaccinated, consider wearing face coverings when in large indoor crowds, and be mindful of symptoms.  Having said all that, running is an activity that can be done alone and with groups -- when running or training alone or in groups, please continue to take all precautions to be a good health steward: keep your distance, wash your hands, and avoid close contact with others.

If you have specific questions, please contact the Run Tucson race directing team at
