Heartland 50 Mile Spring Race

The Heartland 50 is a quintessential prairie endurance event scheduled for Saturday, May 2, 2026, in the small community of Cassoday, Kansas. Known as the "Bloomington of the Plains," the race offers a fast yet challenging out-and-back course that immerses runners in the vast, open expanse of the Flint Hills. This event is designed to be accessible for first-time ultra-runners while remaining a premier destination for veterans seeking a personal record on non-technical terrain.

The geography of the course consists almost entirely of backcountry gravel roads, with less than a mile of pavement in total. The route winds through one of the last remaining large-scale tallgrass prairie ecosystems in North America. A unique aspect of the Heartland course is its "open range" status; runners frequently encounter free-roaming cattle. Participants are instructed to remain calm and walk through herds, as the animals are generally curious but gentle. In early May, Kansas weather is notoriously volatile; while average temperatures range between 10°C (50°F) and 24°C (75°F), the exposed nature of the Flint Hills means that wind and sudden spring storms can significantly alter race conditions.

Logistically, the race is a strictly "no-pacer" and "no-dog" event due to the safety concerns involving grazing livestock. Packet pickup is conducted exclusively on race morning at the Cassoday Community Center from 4:30 AM to 5:30 AM. Runners have access to drop bag services at all manned aid stations, but crew access is limited to specific points (Lapland and Teterville) to prevent traffic congestion on the narrow gravel roads. For those pursuing the "Heartland Double," completion of the spring 50-mile or 50K distance combined with any Heartland distance in October earns a special commemorative award. Current performance benchmarks are high, with Cody Jones holding a notable 2022 time of 6:41:04 for the 50-mile distance.
