The Bun Run is a 5k run/walk that is part of Burger Fest in Seymour, Wisconsin, the Home of the Hamburger. It is a mostly flat 5K with one gradual downhill section toward the end. The run starts and ends at the same location which is Lake Park. Bathrooms and a free swim pond are available. Stay in Seymour for Burger Fest. There's so much to do!!
