Registration will open in early
Registration for the 2021 MadCity Ultra races is now open!
2021 Event Site
We are unable to provide refunds to runners who withdraw from the race. However due to the USATF decision to designate a different event than MadCity for the 2021 100K National Championship, the Local Organizing Committee will contact exiting registrants of the 100K race to discuss options.
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.
