All-Out Summer Breeze

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.

As the summer mornings start to cool, join us for a fantastic end-of-season celebration at our 14th annual Runapalooza! From our new venue at Colorado Tap House, you'll have the chance to tackle relatively gentle 5K and 10K courses that go along the acclaimed Ralston Creek Trail, taking you through shady, creekside beaty along Arvada's picturesque open spaces and charming golf course communities. Or our challenging half marathon course that combines the beauty of the Ralston Creek Trail with the challenging Blunn Reservoir loop with its gorgeous Denver and Front Range views. This event, paired with its Endless Series' counterpart Mardi Crawl, offers a can't-miss opportunity to experience the best of what Colorado has to offer!
