The UPPAbaby CRUZ is not a jogging stroller and should not be used to run. While the Cruz is built with tough, foam-filled rubber tires and front wheels that lock or swivel depending on the terrain, we do not advocate running or jogging with it for a variety of reasons. The front wheel is not designed to handle much weight, so if you add an infant to the mix, you may find yourself with a very unstable stroller. The best way to exercise with your new baby is in walks or cycles. This will help you maintain your fitness level while still giving your baby a good dose of air and light exposure. If you must run with your CRUZ, then we recommend using the double seat configuration or folding it away when not in use.
