The Nautilus Performance Series brings the Nautilus T618 Treadmill to your humble abode. It's exclusively designed to help runners unleash their potential. 

Loaded with 26 performance training programs, it rarely gets better than this. A range of programs is on offer from the interval, heart rate, weight management, and long-distance running. Giving you the option to choose your torture. 

RunSocial programs can be accessed with an iPhone or iPad. Best described as a "mixed reality" platform combining users' avatars with interactive video of real-life routes. 

As you work out on the treadmill, your avatar moves through breathtaking scenes in line with your pace. That's not all, you can plan a virtual run with friends and family or other RunSocial users from around the world. 

Enabling space-saving the T618 treadmill can be folded and stored in a vertical position after use and when in use offers a generous size running treadmill area. 

With a maximum speed capacity of 12 MPH and max inclines of up to 15%, your legs will be put through an arduous workout. 

Advanced cushioning gives impact deflection, softening the landing of your feet at the front of the deck whilst propelling kick-off at the back of the stride which energizes your workout.
