Kettle Moraine 100 Endurance Trail Races
Kettle Moraine 100 Endurance Trail Races is an annual trail event held in June that offers several long-distance options. The 2026 edition is scheduled for June 13, 2026; the race traditionally takes place on the second Saturday of June.
Registration for 2026 uses a lottery system. Lottery signup runs December 1 to December 30, with a drawing on January 1 at 11 am Central; invited entrants have one day to accept or decline. Early invites for rollover entrants and registered volunteers are issued in late November for those who meet the early-invite criteria. A waitlist is used and runners are invited in the order they join it; invited runners may accept or decline.
The course is almost entirely on trail with only a few road crossings, and approximately 65 miles of the route follows the Ice Age Trail. Race logistics information covers aid station locations, drop bags and packet pickup. The event maintains documented volunteer assignments and applies race credits for eligible volunteers. Designated race photographers post edited images, typically within two weeks of the event.
