The all new TomTom Runner Cardio has a built-in Heart Rate Monitor so you get more out of every run. Stay on top of all your essential stats and rip through a run with the TomTom Runner Cardio. Made for the dedicated runner, this TomTom GPS watch comes with a built-in heart rate monitor that accurately tracks your heart rate and allows you to select one of five intensity zones to match your fitness goals. With an extra-large screen, the TomTom Runner Cardio GPS Watch calculates and displays your distance, time, pace, speed and calories burned.

Innovative technology

Get accurate heart rate information without the need for a separate chest strap. Your heart rate is measured through a sensor in the watch that monitors changes in the blood flow in your wrist. This is done by shining light through the skin and detecting the changing light reflections.

Highly accurate

Independent testing has shown that the built-in Heart Rate Monitor is "extremely accurate" compared to electrocardiography.

Five intensity zones

Train in one of five intensity zones, depending on your goal.
  • 5. Sprint: mostly used as part of interval training.
  • 4. Speed: high tempo training to improve your speed and fitness.
  • 3. Endure: moderate to high tempo training to improve your lung and heart capacity.
  • 2. Fat Burn: moderate tempo training, great for weight loss.
  • 1. Easy: easy tempo training, mostly used for warm-up and cool down.
