The Syttende Mai Classic is one of Wisconsin's longest running races. The race distances have changed based on feedback from our participants, race enthusiasts, and race professionals. NEW THIS YEAR - Half marathon run/walk and 5k run! The Half Marathon and 5k Runs are timed races, but the half marathon walk and 2-mile ‘Lil Run are not. Held in conjunction with the city's Syttende Mai celebration.
