Course Records

The MadCity 10K Arboretum Loop course records are held by these outstanding runners!

100K Solo

The 2018 USATF 100K National Champions Anthony Kunkel (6:52:09.8) and Liza Howard (8:07:58.3). 

We anticipate that the 100K Solo will be the USATF National Championship Race for 2021. 

Your finish time in the MadCity 100K will be used as a time standard for selection of Team USA which will compete in the upcoming 100K World Championship race.

The 100K Solo race starts at 6:30AM on race date TBD.

50K Solo

The 50K Solo will once again be a USATF course for 2021. Runners' 50K finish times will be valid in consideration for invitation to join Team USA for the upcoming 50K World Championship.

The 50K Solo race starts at 8:00AM on race date TBD.

USATF Membership

Membership in the USATF is not required to enter the MadCity 100K and 50K Solo races. However USATF membership is required to be declared the USATF 100K National Champion (along with winning the race, of course!).

Course Information

The course is a USATF-certified 10K loop located along the shore of Lake Wingra adjacent to Madison's Vilas Park and winds through the beautiful UW Arboretum. Most of the course is open road with a three-block strech of newly-paved sidewalk.

View the draft course map here.

The course will be open from the start of the 100K at 6:30AM until dusk. Depending on the race date we may extend the course closing time and will recommend headlamps if the race continues after dusk. All runners must complete their race prior to the course closing time.

100K and 50K Solo Race Rules

The MadCity Solo races adhere to the USATF Road Race rules. A complete set of rules is located on the USATF web site.

Runner Gear and Nutrition Drop
