One of the oldest and largest runs in America. The Flood Run has always been a charity event – from throwing sandbags in 1965 to buying a Benefit Wristband to support some great kids today for Gillette Children’s Specialty Health Care. It is estimated that over 30,000 motorcycles come to the run. Motorcycles ride the Wisconsin and the Minnesota side of the Mississippi River Valley. Ride either side of the river, join in wherever you like, cross at any of the bridges from Hastings to Winona.
