Heartland 50, Cassoday KS

Heartland 50 takes place in Cassoday, Kansas on May 2, 2026. The event offers multiple ultrarunning distances:

  • 50 miles
  • 50K
  • 25K

The course is an out and back on backcountry gravel roads with less than one mile of paved surface. Much of the route passes through open range and the Flint Hills tallgrass prairie, where runners may encounter grazing cattle. Course markings include metal washers with ribbon on the road and flour markings on some turns when conditions allow.

Aid station support differs by distance. The 50 mile has five manned aid stations plus unmanned water-only stations, with three crew access points and five opportunities to reach drop bags. The 50K has three manned aid stations and three drop bag opportunities. The 25K has one manned halfway turnaround aid station and unmanned water stations.

Race policies include a 15 hour cutoff for all distances and a requirement that 50 mile runners reach the 25 mile turnaround within seven hours. Runners must wear numbers on the front, check in at each manned aid station, and follow race management directions. No pacers are allowed and dogs are not permitted on the course. Crew vehicles are not allowed on the course. Packet pickup is available race day only at the Cassoday Community Center. Limited free camping is available at Cassoday City Park and other lodging options exist in nearby towns. Visit the organization's website for the most recent information.
