Iola Trail Run

15K & 5K
Iola, Wisconsin

April 14, 2018

Great Lakes Endurance introduced the Iola Trail Run in 2011 and it has quickly become a favorite trail race on the Spring calendar. The venue is the much loved Iola Winter Sports Club with its famed cross country ski trails on rolling terrain carved by glaciers 10,000 years ago. The 15K includes a classic section of the Ice Age Trail. A donation from this event is made to support youth skiing programs at the Iola Winter Sports Club.
