Dog Days Half Marathon

Get ready for some fun in the sun and a great mid-season test of your training as we bring our annual Dog Days 5K, 10K & Half Marathon! Centrally located between Denver & Boulder at Westminster’s award-winning City Park, along with its Endless Series sidekick in December… Fa La La, the beauty of our breathtaking Flatirons as a backdrop will inspire you every step of the way. Plus… Big Dry Creek Trail is well known as a Colorado favorite!

Dog Days benefits Do Over Dogs, a foster-based, 501(c)(3) organization that gives at-risk dogs from the shelter environment a second chance at life. They focus our rescue efforts on dogs and puppies that are at high risk of euthanasia.
