About the race

Ultrapalooza is a ultramarathon held in Osawatomie, Kansas, on the Flint Hills Trail. The event, part of the Kansas Super Slam, offers distances from 5K and 10K up to 50K, 50M, 100K, and 100M, plus a marathon distance. Runners begin and finish at Mile 0 Flint Hills Trailhead, with a flat, crushed-gravel, mostly out-and-back course along prairie, rail-bed towpath sections near the Marais Des Cygnes River.

Aid stations are well stocked and spaced about four miles apart. The weekend features swag, distance-specific hardware, lights, music, a finish-line atmosphere with cowbells and a food truck, and a photographer capturing the spirit. Visit the organization's website for the most recent information.
