TomTom has a new sport watch — the Runner Cardio GPS sport watch — and it's designed to keep an eye on your heartbeat. In fact, it does so in a way that's rather similar to the Samsung Gear 2 and Gear Fit, by using a bright green light Mio optical sensor that is able to track changes in the flow of your blood through your skin. Previous models of TomTom sport watches required a separate wireless monitor strapped around your chest to monitor your heart rate.
The Runner Cardio makes it easy to train in the optimal heart rate zone. Runners can select one of five intensity zones to match their training goals and will receive alerts to know whether they need to speed up or slow down. Runners can see real-time heart rate, distance, pace and other essential running information at a glance, while running.
Those five intensity zones are sprint, speed, endure, fat burn, and easy. Being a GPS watch, the TomTom Runner Cardio also can track your runs and give you detailed data as you're going on your time, distance, and pace. For indoor track and treadmill runners the watch will use motion sensors to get accurate data. It's also waterproof up to 165 feet, gets 10 hours battery life (keep in mind, that's pulling GPS data the whole time), and can connect to a variety of sensors over Bluetooth.
There's also a TomTom Multi-Sport Cardio that can track your cycling, running, and swimming goals and progress. The TomTom Runner Cardio is set to retail for €269 ($370), while the TomTom Multi-Sport Cardio is priced at €299 (US$411).
