Which Garmin watch should I buy?
Garmin offers an overwhelming number of models, which can make it hard to settle on the right watch for your needs. Generally, they can be divided up into the following ranges:
- Forerunner: Designed specifically for road runners, the Forerunner family ranges from the basic (the 55 and 165) to the advanced (the 570 and 970). Historically, its ethos has been 'running watch first, smartwatch second'.
- Fenix: Geared towards recreational and elite athletes, as well as multi-sports, the Fenix offers a comprehensive suit of training, recovery and racing tools.
- Instinct: Built for adventurers, the Instinct family of watches are rugged in appearance, but more wallet-friendly than the Fenix.
- Vivoactive/Venu: Style and design meets health and wellness. Think of the Vivoactive and Venu families as Garmin’s take on the Apple Watch. Unlike the Forerunners, these are more 'smartwatch first, running watch second'. The Vivoactive 6 rivals the Apple Watch SE, the Venu revivals the Series 10, and the Venu X1 rivals the Ultra 2.
When it comes to finding your perfect Garmin watch, it's worth considering what type of running you'll be doing (e.g. on or off road, or a mixture of both) and how much feedback you're after. If you're someone who sticks mostly to roads, a Forerunner will probably fit the bill, with a few different models on offer depending on how nerdy you like to get about your stats.
Spend a lot of time on the trails? The Instinct is designed for you. Or perhaps you're training for a triathlon, in which case the Fenix can handle multi-sports like a pro.
How to choose a Garmin watch
Battery life
Garmin watches come with a wide range of battery lives, and the more you have to spend, the longer you can go between charges. Ideally, you’ll want your watch to survive a week’s worth of training, but you’ll also want to consider the distances and races you’ll be doing – especially if it’s a longer distance like a marathon or an ultramarathon: the last thing you want is your watch cutting out. We'd recommend paying closer attention to the GPS battery life than the smartwatch battery life, particularly if you'll be recording a lot of your training.
Activities/training features
The majority of Garmin watches will be able to track your distance, pace, calories and heart rate data. Higher-end models like the Forerunner 570 and Fenix 8 have more advanced training features such as training status, training readiness and performance condition, which can provide additional feedback to help you improve as a runner.
Garmin watches can also track more than just your runs. Most of them come pre-loaded with a plethora of sporting activities, including cycling, swimming, yoga, strength training, golf and more. The more running-focused watches, like the Forerunner and Fenix, will offer options such as track running, trail running, ultra running and treadmill running. Again, generally the more you pay, the more activities you'll get.
Smartwatch features
Most Garmin watches come with additional health tracking features including sleep and stress monitoring, but the more 'smartwatch' style ones, like the Venu 3 and Venu X1, go seriously more in-depth and pack Garmin's advanced Elevate Gen 5 heart rate monitor.
That said, even the more basic models can let you see notifications for texts and calls, however you’ll usually have to pay for a more premium model if you want things like Garmin pay, weather alerts and phone-free music storage.
Style
Garmin’s line-up spans rugged, adventure-style watches to everyday, smarter-looking watches that wouldn’t look out of place in an office. Consider how often you’ll be wearing your watch (all day or just for workouts?) and where – the likes of the Venu might look sleek and stylish, but it’ll be prone to wear and tear if you’re more of a hardcore adventurer.
