The Tradition continues with the great Colorado Running Classic!

The perfect courses for a relaxing summer holiday! Walk, run, push a stroller, pull a wagon, or let your kids pull you on either the 4K or 4 Mile course! The routes are flat, scenic, safe, and are made up of paved trails and streets, making this a fantastic family event and easy for anyone to participate!
