Report a correctionAbout this race
Held near Cassoday each October since 2000 by the Kansas Ultrarunners Society, the Heartland: Spirit of the Prairie runs out-and-back across the Flint Hills tallgrass prairie on open gravel roads with barely a mile of pavement. Its ultras rise from 50-mile and 100K to 100 and 125 miles, capped at 30 hours for the 100, beside a marathon and half. Rolling hills stack near 6,000 feet of gain, and the shadeless prairie leaves runners exposed to sun, cool 44-to-70F air and relentless wind.
