Kettle Moraine 100, 100k, 50k and 38 mile 

24th annual endurance races

June 1st, and 2nd 2019


This classic ultra marathon was started in 1995 by Kevin and Kris Setnes. They RD'd for 6 years, then Tim "Timo" Yanacheck and Jason Dorgan Co-RD'd until 2018. These four ultra running pioneers built traditions in Kettle Moraine 100 that will carry on for many years to come. Their work is why so many of us are trail and ultra-marathoners. Thank you Kevin, Kris, Timo and Jason for all you have done. You are greatly admired, respected and appreciated by the trail and ultra community.
