The race features a 100-mile out-and-back course primarily on gravel roads, with only a short section of paved surface. Runners experience rolling hills and a substantial elevation gain of 6,000 feet, adding to the challenge. Starting at the original Heartland 100 route, the race includes scenic loops that showcase the breathtaking Flint Hills tallgrass prairie, offering expansive views and a true taste of nature. For those tackling the shorter 100K and 50-mile races, the courses incorporate sections of the Heartland 100 route, allowing participants to relish the same stunning landscapes. The 100K includes a detour to Teter Rock, while the 50-mile route stretches to the Teterville aid station. Each event promises a unique experience amidst the beautiful, rugged terrain.
