TomTom Runner Cardio

 

The TomTom Runner Cardio stands out among GPS watches because it has a built-in heart-rate monitor. The watch is a simple device for people who want to track their running workouts. In addition to heart rate, the device measures the distance, time, pace, speed and calories burned while you run, and displays them on a large, easy-to-read screen. It also displays the time of day. 

Priced at $269.99 on Amazon, the TomTom Runner Cardio is more expensive than the Adidas miCoach Fit Smart (about $190 on Amazon), which also has a built-in heart-rate monitor. But the miCoach is not recommended for swimming, whereas the TomTom is waterproof to 165 feet (50 m). Neither of these trackers will track the amount of time you sleep.


The Runner Cardio is worn like a watch — it comes in one size and has an adjustable, clip-on rubber strap. The whole thing weighs 2.2 ounces (62 grams) and is about half an inch (1.3 centimeters) thick, but doesn't feel excessively bulky. The strap is about 9 inches (23 cm) long, and could be made to fit snugly even on my relatively slender wrist. It was easy to put on the watch or take it off.
