Registration will open in early
Registration for the 2020 MadCity Ultra races will open in December 2019.
We expect that the 100K Solo will once again be the USATF 100K National Championship.

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.
