Summer Sizzler- Denver

Join us for our 14th annual Summer Breeze, benefiting the Food Bank of the Rockies! This event features 5K, 10K, and Half Marathon courses that meander along the Van Bibber Creek Trail, offering breathtaking views of Arvada's open spaces and Table Mountain. The courses are relatively flat, so prepare for a personal record! And continue your achievements with its endless series counterpart, Polar Prowl.

Ready to get off the sofa and gallop around Thornton with some friends? Yeah, you are! Come frolic with us at the Unicorn Runner 5k in Thornton to kick off your summer! You'll earn a sweet tee shirt and a flashy unicorn finisher medal!

It's a 5k distance for all, and whether you walk, trot, canter or gallop, we'll be happy to see you! This event also features a shorter saunter for those not quite ready to enjoy a full 5k! The untimed 3/4 mile run is long enough to get your heart rate up and be a 'real run' without being a sprint!

The Balloon Guy will be back this year- creating balloon creations for all!

Remember to refer your friends and you can earn back up to $20 back from your registration fee. Also - teams of 5 or more each get $5 off their registration. So form a group and get your buddies to join you today!

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.
