How It Works

How It Works

Age grading is a method of leveling the playing field by adjusting for age, gender, and race distance. It’s based on standardized, published data that allows fair comparison across different ages and genders. In this event, that science determines your head start — or lack thereof. 

Runners will start in groups according to age and gender, and will be released approximately every 30 seconds.  Your exact start time and more specific instructions will be emailed to you during race week. 

Why It’s Fun

  • Level playing field: Every age group has a genuine shot at the overall win.
  • Dynamic race atmosphere: You’ll be both the hunter and the hunted.
  • Great for spectators: The finish line will be a great mix of ages and speeds converging.

Details 

  • 10K starting and finishing from Frontier Park in Old Town St. Charles, utilizing roads and some sections of the Katy Trail. The course is mostly flat. 
  • Awards will go to overall finishers — not just by age group — because in this format, everyone is in the same race.  Top 75 overall finishers will receive an award. 
  • All participants will receive a long-sleeve event shirt, finisher’s medal, and lots of finish line fun!
