We are unable to provide refunds to runners who withdraw from the race.
Up to one week prior to race day, a runner may offer to transfer their registration to another runner for the same race. The registered runner must contact the MadCity local organizing committee with the complete information regarding the transfer, and the runner who will be competing in their place must complete the race waiver form.
