Get ready for a unique 10K experience at The Great Chase, set to invigorate the St. Louis area on September 13, 2026. This isn't your typical mass-start event; it's a thrilling age-graded pursuit where every runner, regardless of age or gender, has a legitimate shot at the overall win. Utilizing official age-grading tables, participants receive staggered start times, transforming the race into a dynamic "hunter and hunted" scenario that builds to an electrifying finish line showdown. The oldest women lead the charge, with the youngest, fastest men starting last, aiming to chase down everyone in front of them.

The Great Chase 10K begins and ends in scenic Frontier Park in Old Town St. Charles, guiding runners along a mostly flat course that utilizes both roads and sections of the historic Katy Trail. This provides a pleasant backdrop for your strategic chase. Typical race day conditions in mid-September often bring comfortable highs around 82°F and lows near 60°F, with a modest 11% chance of precipitation, creating a favorable environment for personal bests. Each participant will be rewarded with a long-sleeve event shirt and a finisher's medal, complementing the festive atmosphere and finish line celebrations. The innovative format promises an engaging experience for both runners and spectators, making it a must-do event on the 2026 racing calendar.
