    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!

The untimed 3/4 mile run is long enough to get your heart rate up and be a 'real run' without being a sprint!
