The course

Where it goes

The 125 mile race starts Friday night. It begins on the original Heartland 100 course with a 30 mile loop out to Eureka, Kansas, beginning at mile 15, then joins the 100 mile course. Runners get a map with turn by turn directions and the Eureka loop has little course marking. A roving aid station covers the first night.

The race

What this one is

Heartland, Spirit of the Prairie, is a fall ultra in Cassoday, Kansas, run on backcountry gravel roads through open range in the Flint Hills tallgrass prairie. The 100 mile course is an out and back with about 6,000 feet of climb, and there are shorter distances, a marathon and a half marathon on parts of the same roads. A 125 mile option starts Friday night.
