MadCity Ultras

Since 2007 this race has encompassed a beloved local loop known as the Arb Loop. This is a 10K loop that includes the beautiful landscape of the UW- Madison Arboretum. Once again MadCity will host the USATF 100K National Championship, along with the 50K Solo and 50K Relay. New in 2024 - we've added a 100K Relay to our event.
