Still rowdy since 1989, the Underdown Trail Races are grassroots trail runs in Northern Wisconsin. It’s conveniently located only 6 miles off of Highway 51 and offers runners a wilderness experience on challenging trails formed from glaciers that swept the area thousands of years ago. The course is primarily singletrack climbing hills (up to 75!) that pass by isolated lakes and dozens of boardwalks.The race will be held concurrently with the Thunderdown in the Underdown Wisconsin Endurance Mountain Biking Series (WEMS) races.
