Multi-State Running Series
The Center of the Nation Series is a multi-day event spanning six states over six consecutive days. Participants have the opportunity to complete races in Wyoming, Colorado, Nebraska, South Dakota, North Dakota, and Montana. The series is designed with a high level of flexibility, allowing athletes to participate in any number of races, from a single day to the full six-day circuit.
The event utilizes a multi-loop course format at each location. Every race site features a central aid station providing a wide variety of food and beverages, including fruit, sandwiches, coffee, and sports drinks. There are no time limits for any of the distances, and the event maintains a policy of remaining open until the final participant finishes. Both runners and walkers are welcome to participate.
Available distances include:
- 50K
- Marathon
- Half Marathon
- 10 km
- 5 km
Each day features a different course surface and setting. Locations include Lions Park in Cheyenne, Wyoming; Pioneer Park in Sterling, Colorado; Chadron State Park in Nebraska; Rocky Point Recreation Area in South Dakota; North Shore Marina at Bowman-Haley Lake in North Dakota; and Triangle Park in Baker, Montana. Surfaces vary between paved concrete, asphalt, and fine gravel trails. All participants receive a shirt and a series of connecting medals for each completed state, with a bonus medal for those who finish all six days.
