Lining up for your 13th year, this mid-season race brings you a 5K, 10K, and half marathon through Westminster's scenic Big Dry Creek Trail, positioned conveniently between Denver and Boulder with stunning Flatirons views along the way. Your furry running friends are welcome too—the route features plenty of soft trail surface, plus there's a special dog racing division and costume contest to keep things entertaining while supporting Do Over Dogs. If you're looking for more fun, you can carry the momentum into December with the Fa La La race series!
