The Ice Age Trail 50 is one of the oldest continuously-running ultras in the country. A course like no other, you’ll run in dense deciduous forests, under tall pines, over rocky ridges and across open prairies – and see lakes, kettles, kames, erratics and other natural features left when the glaciers finally retreated from Wisconsin more than 10,000 years ago.

Overview
Course Description
The Half Marathon course begins and ends in the finish area near the Nordic Trail parking lot. The two-loop counter-clockwise course was designed to take runners through a variety of vegetation, hardwoods, pine plantations, open meadows and kettle moraine terrain. The Half Marathon course is marked with BLUE ground flags.
Enjoy your run on the Nordic Trail. The trails are very wide, scenic and runnable. There are hills, but also sections in the pines and meadows where you will want to develop some speed. Many areas that were rocky have been wood chipped over to help skiers save their equipment.
The loop you are running is very representative of the glacial topography and natural diversity of the Kettle Moraine. As a cross country ski trail, it provides every type of terrain imaginable for skiing.
