From the Organizer
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!
