Experience Ultrapalooza, the ultimate running celebration in the Midwest, featuring a remarkably flat course! Participants will traverse the stunning Flint Hills, which preserve one of the world's final tallgrass prairie ecosystems. The trail meanders along the picturesque Marais Des Cygnes River, surrounded by majestic bluffs, lush farmland, and verdant woodlands. As the longest rail-trail in Kansas and the seventh-longest in the U.S., it traces the historic Santa Fe National Trail and contributes to the coast-to-coast American Discovery Trail.
