Welcome to MadCity Ultras!
We feature three races - the 100K and 50K Solo and 50K Relay. The 100K is the USATF National Championship Race and USATF members' finish time in the MadCity 100K will be used as a time standard for selection of Team USA which will compete in the 2018 100K World Championship race.
The 50K is also a USATF Certified course and your finish time will be valid for the 50K World Championship.
The 50K Relay is for teams of 2-5 runners on the same 5K loop course. Our relay teams are fantastic cheering sections for all the runners, creating a great race day environment.
