St. Charles Runners Club Flat Five

The St. Charles Runners Club Flat Five is an annual running event held at Frontier Park on South Riverside Drive in downtown St. Charles, Missouri.

The 44th edition features a 5-mile timed race along the scenic Katy Trail, designed as an out-and-back course to minimize city street impact. Additional events include a 1-mile fun run/walk and a Tot Trot for toddlers. The race offers water stations, post-race food, and awards for top finishers across various age groups.

Participants receive a soft-style shirt, and live race results are provided on-site. The event fosters a friendly, community atmosphere supported by local sponsors. Visit the organization's website for the most recent information.
