The Kettle Moraine 100 course runs entirely on trails (except for road crossings) and will traverse the Ice Age National Scenic Trail for 65 miles.

The course consist of 2 different out and back sections. You will find the trail to be about 80% wooded terrain, with the rest meandering through prairie or marsh areas. Part of the course will be a roller coaster of hills, with rocks and roots scattered about to various degrees. Other sections will be gently rolling with relatively smooth running surfaces. The pine sections give you that soft bed of pine needles that so many of us like to run on. Though the hills are not long and/or especially steep, they can take a tremendous toll on you if you attempt to run them. We have a total altitude gain of approximately 8,800 feet.
