Heartland 50

Heartland 50 is an ultrarunning event in Cassoday, KS, scheduled for May 1, 2027. The event offers three distance options:

  • 50 miles
  • 50 km
  • 25 km

The course is an out-and-back on backcountry gravel roads with less than one mile of paved surface. Much of the route runs through open range and the Flint Hills tallgrass prairie. Parts of the course may have cattle grazing; runners are instructed to remain calm and walk through herds rather than run or shout.

Aid station and support details vary by distance. The 50 mile distance has five manned aid stations plus several unmanned water-only stations, with crew access at three points and multiple drop bag opportunities. The 50K has three manned aid stations and drop bag access at those stations. The 25K has one manned halfway turnaround aid station and water-only unmanned stations. Drop bags must be clearly marked with the runner name and bib number and left at the start/finish staging area before the race.

Race rules include wearing numbers on the front, checking in at each manned aid station, no littering, no pacers, and no dogs on the course (leashed dogs are allowed at aid stations). Crew vehicles are not allowed on the course during the race except as specified in the race directions. Cutoffs include a 15 hour overall limit for all distances and a 7 hour requirement to reach the 25 mile turnaround for 50 mile entrants; some intermediate cutoffs will be announced.

All finishers receive a Sport Tek tank top and a finisher award. Race day photos will be available for free download. Entry fees are listed between $150.94 and $196.31 USD. Registration closes April 19 and there are no deferrals after that date. Visit the organization's website for the most recent information.
