Heartland 50 : Cassoday, Kansas

The event offers three out and back distances on backcountry gravel roads with less than one mile of paved surface. Much of the course runs through open range with views of the Flint Hills tallgrass prairie. The course is described as non-technical and uses metal washers with ribbon for marking on the road; flour may be used for some turns when conditions allow.

Distances

  • 50 mile
  • 50K
  • 25K (The Heavy 25K)

Aid and crew support vary by distance. The 50 mile race has five manned aid stations plus unmanned water stations, with crew access at three points and drop bag access five times. The 50K has three manned aid stations and three drop bag opportunities. The 25K has one manned halfway turnaround aid station with one drop bag access and no crew access at that station. Drop bag service is available at manned aid stations.

Cutoff and race procedures include a 15 hour cutoff for all distances and a 7 hour requirement to reach the 25 mile turnaround for 50 mile entrants. Runners must check in at each manned aid station and wear numbers on the front and outside of clothing. Crew vehicles are not allowed on the course except at designated access points. Rules prohibit pacers and dogs on the course; parts of the route cross open range with cattle present. Finishers receive a tri blend shirt and a finisher award. Free race photos will be available after the event. Visit the organization's website for the most recent information.
