From the organizer
Get ready for a sun-soaked adventure and a fantastic mid-season challenge with our 13th Annual Dog Days 5K, 10K & Half Marathon, benefiting Do Over Dogs! Held in a central location between Denver and Boulder, our courses wind northeast along the scenic Big Dry Creek Trail. As you run, you’ll enjoy breathtaking views of the Flatirons on the horizon. Our trail is perfect for dogs, featuring a generous amount of soft surface along the 10K and half marathon routes. Plus, we have a special dog division to award the fastest pups at each distance and a dog-themed costume contest for extra fun! And continue the challenge by participating in the endless series counterpart, Fa La La, in December.
