The Great GO! St. Louis Halloween Race

The Great GO! St. Louis Halloween Race is a weekend of themed running events held in Eureka, Missouri, with the finish area and many activities centered at Kircher Park. The event offers multiple race distances, a costume contest for participants, and a dedicated 1-mile dog walk called the Great PUPkin Run where leashes are required and costumes are encouraged.

Distances:

  • Half Marathon
  • 10K
  • 5K
  • 1-Mile Fun Run
  • 1-Mile Great PUPkin Run for dogs and their humans

Participants receive a premium long sleeve shirt, a festive finisher medal, a digital finisher certificate, and a post-race treat bag. The event includes a Trick-or-Treat Village in Kircher Park, post-race candy, and Schlafly beer available for participants over 21. A puppy costume contest offers extra prizes and a live costume contest is held for each distance, with awards from local businesses.

Age-group awards and special prizes are part of the competition: the first three finishers in each age group for the Half Marathon, 10K, and 5K receive a pumpkin pie; prize money is awarded to the top three male and female finishers in the 10K and Half Marathon ($300, $200, $100). Pets are allowed only in the Great PUPkin Run. The races enforce time limits and require participants to display race bibs. Visit the organization's website for the most recent information.
