TomTom is taking its knowledge of automotive GPS to the fitness world with the $169 Runner GPS watch. This light and comfortable wristwatch can track your runs - both outdoors and on a treadmill - and then uploads the data to one of several fitness sites.

Comfortable to wear; Easy to read while you run; Intuitive controls; Good battery life

Can't sync workout data via Bluetooth; Doesn't record split times

The watch performs as advertized. It is very light weight and easy to use while running. The results appear to be accurate. I am fairly obsessive about recording the length of my runs and this watch gives me the ability to vary my routes daily and still have an accurate measurement of the distance.

Wearable tech is all the rage at the moment, particularly smartwatches. It's hardly a surprise, then, that plenty of manufacturers want a slice of the pie.

TomTom's latest entry into what has become a busy sports GPS watch market is a slim-profile, proficient watch with a range of innovative features that set it apart. It's thinner (less than half an inch) than any other GPS watch on the market, thanks in part to the fact that some of its mass,...

The TomTom Runner GPS Watch is the company's latest offering within the running category after a few years of partnering with Nike. So it was a bit expected that they would be releasing a dedicated unit for runners.

I kept seeing this watch in my Fitness Magazine and I was like that's pretty cool. So I did some research and found that I really needed it in my life

If I reviewed the TomTom Runner GPS watch based only on how fast it made me run, it would score top marks. With this sports watch strapped to my wrist one afternoon, I ran like no tomorrow, clocking a speed I had not seen in years.

TomTom has quickly moved into the GPS fitness watch market and looks set to give the leading supplier, Garmin, a real run (pun intended) for its money.

Overall this is a good GPS watch for runners of all levels. At $349 it may be a little pricey for some but given the range of features, it’s a worthwhile buy.

Built-in heart rate monitor; Comfortable and easy to use with single button control; Online dashboard provides very useful information;

It’s a tad expensive. If you’re not too fussed about the heart rate monitor, the entry-level TomTom Runner is significantly less expensive at $199;

I bought this after contemplating over a few heart rate monitor watches. This does it all:Great GPSWith the built in HR monitor its a no brainer and it's accurate tooWell done TomTom

Although it does not have as many features as some other smart watches for serious runners this is a good piece of kit. The mapping accuracy and GPS fix are excellent. Updates are regularly provided to add new functions
