How To Choose The Best Running Watch: The Complete Buyer's Guide

A running watch has become one of the most popular pieces of technology a runner can own. From tracking your distance and pace to monitoring heart rate, sleep and recovery, today's GPS watches can provide an incredible amount of information about your training. For some runners they are an invaluable coaching tool, while for others they are simply a convenient way to record their runs.

With so many models available at vastly different prices, choosing the right running watch can feel overwhelming. The good news is that you don't need the most expensive model to become a better runner. Understanding which features genuinely matter will help you buy a watch that suits both your training and your budget.

Do You Actually Need A Running Watch?

Plenty of runners successfully train using nothing more than a comfortable pair of running shoes and, if they want to record their runs, a smartphone. If you're just getting started, your focus should be on building consistency rather than analysing every statistic your watch produces.

As your running develops, however, a GPS watch can become increasingly useful. It allows you to track your progress accurately, monitor improvements over time and follow structured training plans more easily. For runners training towards specific goals such as a 10K, half marathon or marathon, the information provided by a running watch can help make training more effective.

What Does A Running Watch Do?

At its most basic level, a running watch records your route using GPS and calculates your distance, pace and time. Most modern watches also monitor your heart rate using an optical sensor on the underside of the watch, allowing you to see how hard your body is working during each run.

Many watches now go much further than simple GPS tracking. Depending on the model, they can estimate recovery time, measure sleep quality, monitor stress levels, suggest daily workouts and even provide detailed maps for navigation. While these additional features can be useful, they are not essential for every runner.

GPS Accuracy

One of the biggest advantages of a dedicated running watch over a smartphone is GPS accuracy. Running watches are designed specifically to track movement during exercise and often use multiple satellite systems to improve positioning, particularly in built-up areas or under tree cover.

Even so, no GPS device is perfectly accurate. Tall buildings, dense woodland and poor satellite reception can all affect recorded distances. Rather than worrying about tiny differences between devices, it is better to use the same watch consistently so you can compare your own training over time.

Heart Rate Monitoring

Most modern running watches include wrist-based heart rate monitoring, making it easier than ever to keep track of your effort during training. This can be particularly useful if you follow heart rate zones or want to ensure your easy runs really are easy.

Although wrist sensors have improved dramatically, they are not always as accurate as chest strap monitors, particularly during interval sessions or activities involving rapid changes in pace. For most recreational runners the difference is unlikely to matter, but those who require the highest level of accuracy may still prefer to use a chest heart rate monitor alongside their watch.

Pace, Distance And Training

Perhaps the greatest benefit of a running watch is the ability to monitor your pace throughout a run. Instead of relying purely on feel, you can quickly check whether you're running too fast on an easy day or maintaining your target pace during a tempo session.

Distance tracking also becomes much simpler, allowing you to complete structured sessions without needing to measure routes beforehand. Whether you're following a couch-to-5K programme or preparing for your first marathon, having reliable pace and distance information can make training much easier to manage.

Navigation And Mapping

Many mid-range and premium running watches now include mapping and navigation features. These allow you to follow pre-planned routes, explore unfamiliar areas with greater confidence or retrace your steps if you become lost.

Trail runners and ultramarathon athletes often find these features particularly valuable, although they can also be useful for runners travelling to new cities or looking to add variety to their usual training routes.

Battery Life

Battery life varies enormously between different running watches. Entry-level models may comfortably last several days between charges, while premium GPS watches can often record dozens of hours of activity before needing to be recharged.

If you're mainly running 5Ks and 10Ks, battery life is unlikely to be a deciding factor. However, runners training for ultramarathons or multi-day events should pay much closer attention to battery performance, particularly if they plan to use GPS navigation throughout long races.

Smartwatch Or Running Watch?

Many modern smartwatches include running features, leading some runners to wonder whether they need a dedicated sports watch at all.

For casual runners, a smartwatch may provide everything required, including GPS, heart rate monitoring and basic activity tracking. Dedicated running watches, however, generally offer longer battery life, more advanced training tools, better durability and improved GPS accuracy. If running becomes a significant part of your lifestyle, a purpose-built running watch will usually provide a much better experience.

Music, Payments And Everyday Features

Running watches are no longer just training tools. Many now allow you to store music, make contactless payments and receive smartphone notifications, making them useful throughout the day as well as during exercise.

These lifestyle features are convenient, but they shouldn't be your main priority when choosing a running watch. Comfort, GPS accuracy, battery life and ease of use will usually have a much bigger impact on your enjoyment as a runner.

How good is the app that supports the watch?

Consider The App As Well As The Watch

When comparing running watches, it's easy to focus on the hardware and overlook the software that you'll actually use every day. Every major manufacturer has its own companion app, where your runs are uploaded, analysed and stored. This is where you'll review your training history, create routes, follow training plans, monitor recovery and often connect with platforms such as Strava. Some apps are intuitive and packed with useful features, while others can feel less polished or offer fewer insights.

Before buying a watch, spend a little time researching the quality of the app as well as the watch itself. Reading reviews and, if possible, trying the app can help you decide whether it suits the way you like to train, as you'll probably spend just as much time using the app as you do looking at the watch on your wrist.

Should Beginners Buy An Expensive Watch?

It is easy to assume that buying the most expensive running watch will automatically make you a better runner, but that simply isn't true. Beginners are often better served by a straightforward GPS watch that accurately records distance, pace and heart rate without overwhelming them with advanced data.

As your running progresses and your goals become more ambitious, you can always upgrade to a model with additional features if you feel they will genuinely improve your training. Spending hundreds of pounds on functions you never use is rarely good value.

Popular Running Watch Brands

Several manufacturers have established excellent reputations within the running community, each offering watches aimed at different types of runners.

Garmin remains one of the most popular choices thanks to its extensive range, excellent GPS accuracy and comprehensive training features. Coros has gained a loyal following by offering impressive battery life and performance-focused watches at competitive prices, while Polar continues to produce highly regarded training watches with strong heart rate capabilities. Suunto is particularly popular with trail runners and adventure athletes, and the Apple Watch has become an increasingly capable option for runners who also want a smartwatch for everyday use.

Trying different brands is worthwhile, as each has its own software, navigation system and ecosystem that may suit some runners better than others.

Final Thoughts

A running watch is a fantastic tool, but it is exactly that, a tool. It can provide valuable information about your training, help you monitor progress and make structured sessions easier to follow, but it cannot replace consistent training, sensible recovery or simply enjoying your running.

If you're new to the sport, don't feel pressured into buying the most advanced watch available. A simple, reliable GPS watch is more than enough for most runners and will provide all the information you need as your experience grows. By choosing a watch that matches your current goals rather than the latest trends, you'll invest in technology that genuinely supports your running rather than distracting from it.
