Race Information
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.
