The Ice Age Trail 50 is one of America's "classic" ultramarathons. Run mostly on the Ice Age National Scenic Trail in southeastern Wisconsin, the course takes runners on a tour of the unique geologic features left by the last Ice Age 10,000 years ago. Evergreen and deciduous forests, natural prairies, ponds, marshes and kettles are all part of this diverse and beautiful landscape. Rated 3/3 by Ultrarunning magazine, the terrain varies from rolling cross country ski trails to twisting, root and rock-covered single track. The race begins and ends about one hour southwest of Milwaukee, an hour southeast of Madison and roughly 1.5 hours northwest of Chicago. The 2013 50-mile race is honored once again to be part of the Montrail Ultra Cup Championship Series, the final series event before the Western States 100 in June.
