Whether you’re just starting out or you’re well on your way to becoming a member of the 100 Marathon Club, tracking your runs can be a brilliant motivator and improve performance. But choosing the best GPS running watch for you can be just as tricky as picking out the perfect pair of running shoes.

It’s a decision that’s not getting any easier either. Back in the day it would have be Garmin, Polar or Casio stopwatch but now there are now countless brands and hundreds of products to choose from.



So with scores of running apps, smartwatches that do running, running watches that are a bit smart, plus a whole myriad of fitness tracking bands, it’s tough to know where to start? Luckily our marathon man and running tech expert Kieran Alger, is here to help with his tips for finding the ideal training partner.

Why buy a running watch?

It might seem like an odd question to ask in running watch buying guide but it’s actually really important. If you own a smartphone and are willing to carry it on a run, then there are loads of apps that’ll give you 90 per cent of the features you get on most GPS running watches, for free or for a budget friendly subscription fee.

A lot of these apps like Strava, Endmondo, Nike+, Runtastic and Runkeeper also offer rich community features that you might not get with your running watch. So it’s really worth thinking about that before you rush and spend $300.

However, what these apps don’t do so well is put your vital real-time tracking information where you can see it. Granted they’ll offer over-the-earphone updates on distance, splits and the like but it’s not as useful as having it available at a glance on your wrist. Particularly if you also don’t always run with headphones. You can’t beat a running watch for real time insights.

How much should you spend?

Let’s talk money first. Running watches range from $50 to $600. It’s loosely the case that the more you spend, the more features you get but not all of those extra features might be necessary for your running needs.

An entry level watch like the Garmin Forerunner 10 will set you back $99.99 and comes with all the basics you need to track a run, including GPS, pace, distance and calories. At the other end of the spectrum you’ve got something like the Suunto Ambit3 Peak Sapphire HR that’ll lighten your wallet by $600 has everything from a compass to vertical gain and offers tracking across a whole range of sports.

As a rough ball park here’s what you can expect to get for the dollar you spend:

Sub$150:You’ll get budget options like the Runtastic Orbit and Magellan Echo, that come with limited features, often without GPS and relying on smartphone pairing. On the plus side they’re often nice and compact, lightweight and the data you get, while minimal, is very simple.

In this bracket you’ll also get a lot of fitness trackers that claim to having running smarts. Lots of these will count steps and turn them into a estimated distance covered but largely they’re not great tools for running.

From $150 to $300 Entry to mid-level watches like the TomTom Runner, Fitbit Surge and the Polar M400 start to come with heart rate tracking, built in accelerometers to keep tabs on indoor runs, enhanced training features like heart rate zone training and interval session programmes. They’ll be supported by more extensive apps and online tools and largely let you leave your smartphone at home.

$300+: Once you go beyond $300 you can start to expect a lot more detail. Real time running coaching with insights such as cadence and vertical oscillation design to help improve your form. At this end you’d also expect full indoor-outdoor tracking, post-run smarts like tips on your training load and recommended recovery time.

Running watch vs smartwatch

It’s worth noting that at $250+ you’re also in smartwatch territory with devices like the Apple Watch, Samsung Gear and Sony Smartwatch 3 all offering some run tracking either through native apps or third party apps like you get on your smartphone. If you’re a serious runner, looking for serious insights then these are probably not for you. Although they could be a good option for occasional runners considering a smartwatch for whom run tracking is a bonus feature.

So before you go any further, there’s a bit of soul searching to be done.

Plot your trajectory

Rather than thinking about where you are now as a runner, try to figure out where you’ll be in 12 months time. You might just be starting out but if your running ambitions are to constantly improve, pushing longer distances and taking on bigger running challenges then you might want to opt for something a bit more capable. In which case a mid-range running watch that you can grow into is a better bet.

If you’re only ever going to run a few times a week for fun but want to record a few key stats then stick with one of the capable lower-end devices.

Equally, if one day you hope to be racing Kilian Jornet (look him up, you won’t believe what this man can do) up a mountain then you’ll want to invest in a solid adventure watch that’ll go on that journey with you.

To help you narrow down your search, here’s a list of questions to ask.

What features do you need?

Do you want to track your distance?

We’ll presume this is a big fat yes. There are a few ways watches do this. There’s built in GPS, piggybacking your phone’s GPS, using a built in accelerometer or with a shoe pod with an accelerometer. The latter is pretty outdated now but some people still offer it. We’d argue that built-in GPS is a must have. Also look consider watches that have built in GPS and accelerometers that can be used to smooth out any gaps in GPS data.

Do you want heart rate monitoring?

If you’re serious about training then heart rate monitoring can be very useful. You get two choices here, built in optical heart rate (OHR) or a chest strap. The latter tends to be more accurate but if you don’t like the chest strap for comfort reasons then go for OHR but don’t expect it to be 100 per cent spot on.

Do you run a lot indoors on treadmills?

If so, and you want your data in one place, then go for a watch with a built-in accelerometer and indoor run option.

Do you want help with training plans?

A lot but not all brands offers off-the-shelf expert training plans for 5k, 10k, half and full marathons. If this is important then check out the partner web tools and smarpthone apps to make sure they do. Adidas, Garmin and Polar arguably offer the most comprehensive.

Will it let me create interval training sessions?

Interval sessions are an excellent way to build fitness and speed. Devices like the Garmin Forerunner 225 will let you create infinitely customisable interval sessions, combing things like pace, distance, heart rate and duration.

Do you want to improve your running form?

You start to get into a bit more serious nitty gritty here but increasingly the higher end running watches are offering extra insights on running dynamics. You can get real time feedback on cadence, or how often your feet strike the floor in a minute and vertical oscillation, all of which is aimed to help guide you to a more efficient running form.

Does it offer heart rate zone training?

While some devices will offer heart rate tracking, not all of them provide real-time heart rate zone training. Adidas SmartRun, the TomTom Cardio Runner and the Polar V800 all offer this, letting you see when you’re working in different zones from fat burn to aerobic capacity.

Do your want advice on recovery?

Again, this one’s probably more important for the serious runners but you can now get watches that offer post-run advice on your training load and a recommendation of how long you should rest before you head out again.

How much time will you spend drooling over data?

If you plan to analyse your data on a regular basis for marginal gains, then it’s worth downloading the app and the web tools before you splash out. Some very capable watches have fairly awful online tools.

Does it offer wireless syncing over Bluetooth or WiFi?

Ask anyone who’s ever faffed about with an ANT+ dongle USB widget plug in to sync their data and they’ll tell you wireless WiFi or Bluetooth data sharing via a smartphone is definitely the way forward.

Will my wrist look small in this?

Another fairly obvious but often overlooked point is how your watch fits on your arm. If you’re a tiny-wristed runner then a great hulking Suunto might not be ideal.

How long will you be running for on your longest runs?

Ah yes, the battery life question. Most watches will last a good 5 hour marathon but only a handful will handle a 13-hour ultra without back-up power packs.
