The Thirsty 13 Half Marathon is one of the best races in Colorado! The race course: Fast and mostly downhill, with gorgeous scenery. Perfect for runners new to the half marathon distance or looking to set a PR. The finish line: Ska Brewing, one of the best breweries in Colorado. A crowd of spectators cheers you to the finish.

When you cross the finish line, we'll put an official Thirsty 13 finisher's mug in your hand, and send you to the bar where you can fill it with a complimentary Ska beer or N/A beverage. And get ready for the best finish line food you've ever had. Results are available in real time at the timing company kiosk at the finish line. The awards ceremony will begin at 11am.
