St. Charles Runners Club Flat Five
The St. Charles Runners Club presents the 45th Flat Five on August 2, 2026 at Frontier Park on South Riverside Drive in St. Charles, Missouri. The event uses an out-and-back course on the Katy Trail to reduce impact on city streets. Course marshals will staff road crossings, the water stop, and the turnaround, and a lead and trailing bike will monitor participant safety.
Distances offered:
- 5 Mile timed race
- 1 Mile untimed fun run/walk
- Toddler Trot approximately 50 yards
There are two water stations on the Katy Trail, one just north of DuSable Park and one south of DuSable Park, with volunteers handing out cups. Post-race food will be available at the Frontier Park bandstand. Live results will be provided on-site by Start 2 Finish St. Louis via text and email, and awards will be distributed at an awards ceremony; awards not claimed at the ceremony may be picked up later at Fleet Feet St. Charles beginning Wednesday, August 6.
Packet pickup is encouraged at Fleet Feet St. Charles on Saturday, August 1 (10:00 AM to 4:00 PM). Race morning packet pickup and day-of registration are available at Frontier Park. Registrants for the 5 Mile receive a soft style short sleeve shirt; 1 Mile participants may purchase a shirt for an additional fee. The St. Charles Runners Club is a nonprofit sanctioned by the Road Runners Club of America. Visit the organization's website for the most recent information.
