Ready to get off the sofa and gallop around Highlands Ranch with some friends? Yeah, you are! Come frolic with us at the Unicorn Runner 5k in Highlands Ranch to finish 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!
Costumes are encouraged!
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 in the 5k each get $5 off their registration. So form a group and get your buddies to join you today!

Miles 4 Madison is a 5K/1K Fun Run supported by Sterling Ranch CAB. Miles 4 Madison's goal is to provide educational and recreational opportunities for families with children with different abilities. The Race is for all capabilities, strollers, and pet-friendly! Race registrations done after 9/10 won't be guaranteed the selected shirt size.
After the success of previous years races, Miles for Madison provided scholarships for several Douglas County children to attend the week-long summer camp at Easter Seals Rocky Mountain Village as well as attend hippotherapy in Douglas County. We have been able to donate playground equipment to local schools and have hosted multiple sensory-friendly events in Sterling Ranch, including Sensory swim and, most recently, a sensory-friendly egg hunt. Miles for Madison is also working to build inclusive parks in the Chatfield Basin.
The race will take place at Providence Park, located within the Sterling Ranch Community. The race address is 8100 Piney River Avenue, Littleton, CO 80125.
Prizes will be awarded to the top 3 finishers in the 5 K, male and female.
