About Heartland Spirit of the Prairie Race

The 100-mile cross-country run will take participants through some of the last remaining tall grass prairie in the United States. “Spirit of the Prairie” was chosen as the theme for this race in tribute to the early explores who crossed this land, the Native Americans who hunted on this land, and early settlers and ranchers who called the Flint Hills home.
