Logic tells us not to step outside when everyone else is still asleep. It says two minutes faster is not realistic. It tells us to rest when we are tired and to give up when it hurts. Defy logic with the Spartan Sport GPS Watch with Optical Heart Rate from Suunto. Made for experienced endurance athletes, this multisport GPS watch is made to be the ideal training and racing partner for running, cycling and more. With expertise and support for more than 80 sports, the Suunto Spartan Sport HR helps you exceed your goals with your workout of choice. Boasting a durable color touch screen, this updated Spartan Sport is water resistant up to 100m, provides practical wrist HR measurement and allows for up to 12h of battery life in training mode. The all-new Spartan Sport Wrist HR Baro has all the explosive features of the Spartan Sport HR, but includes a barometric altimeter - making it great for trail runners, mountain bikers and outside enthusiasts alike. The Baro uses Suunto’s FusedAlti technology, combining GPS and barometric data for more precise altitude information. The watch also displays sunrise/sunset times, and gives storm alarms when a sudden drop in air pressure occurs.
