No matter whether you are new to the world of running or a seasoned pro, you will be keen to know how far you have gone, how long it has taken you and the other available statistics relating to your run. This is where the GPS activity tracker comes into its own, and for many is a key part of your running kit! From an entry level watch that just tells you the basics to a watch you can use to programme and navigate your watch, there are plenty of options. We chose the Garmin running watches range specifically because they are our watch of our choice and we reckon for every 10 runners we encounter, approximately 9 of them own a Garmin of some description.

Let’s start our overview of Garmin running watches with the watch for the experienced endurance runner that wants to invest a bit more into an activity tracking device:

    Garmin Fenix 7 Solar

    Best Trail/Ultra Running Watch 

    The Garmin Fenix 7 is perfect for the trail runner who likes a high level of data and additional features to enhance their run. Being able to load your routes and use it to navigate is perhaps the top of the list for trail enthusiasts. Not only that but the track back feature of the upper end of the range means you can retrace your steps should you take a wrong turn or find yourself in unknown territory. 

    Advanced training features of the Garmin Fenix 7 (just one of the many watches in the range) include pacepro for grade-adjusted pace guidance throughout your activity plus environmentally adjusted VO2 max and training status estimates. Set up your data screens and create your own preferred display to show elevation, pace, distance, heart rate… you choose!

    Having a Fenix ourselves means we can happily recommend this particular watch. Having gone from following GPX routes on mobile phones and OS maps to being able to upload the route to a watch means that we save so much time and the margin for error significantly reduces. No longer do we have to worry about taking a wrong turn and the track back feature means that we can always find our way home. We first used this during a 50 mile ultra. We knew the route so it was the perfect way to test that it was accurate. It certainly was. 

    Set Your Chosen Data Screen

    We also love the fact that you can set your own data screen. Personally we like to see the distance covered, the elevation and the time. Not something you can do with the more basic watches. The Garmin 235 for examples requires you to toggle between screens to get what you ideally want. If your’e into your trail running and want to invest in a decent running watch then it’s most definitely worth it.

    Garmin Forerunner 945

    Best for Multi-Sport and Competitive Runners

    The Garmin Forerunner 945 GPS running that is suitable for triathletes and those that are serious about running.

Adjustments can be made for heat, altitude acclimation status, training load focus, recovery time and more. In Smartmode, the battery will last up to two weeks, this reduces to 10 hours in GPS mode – enough to get you round that half Ironman. If you’re a marathon runner, it’s got more than enough battery life however, for the ultra runner or Ironman, you are going to need something with more battery life.

    Maps, Safety and Tracking Features

    With a full colour screen, you also have access to full colour maps plus the safety and tracking features include incident detection during select activities. We were informed by a fellow runner that they tripped up a step at home which triggered an alert to their husband so we know this feature works. Out and about without your wallet? no problem. This Garmin 945 GPS watch also features Garmin Pay contactless payment solution which means you can make payments from your watch.

    Garmin Forerunner 35

    Cheapest Garmin Watch for Entry Level

This GPS will track your distance, time and pace as well as tracking heart rate at the wrist. The batter life of the Garmin Forerunner 35 is 13 hours in GPS mode or 9 days otherwise. That is some impressive battery life.

    Garmin Forerunner 245 GPS Running Watch

    Best Mid Range Garmin Watch 

    A popular choice among road and off road runners is the Garmin Forerunner 245 GPS watch. It tracks heart rate via Elevate Wrist Heart Rate technology, gives an VO2 Max estimate and acts as a recovery advisor. Automatically uploads to Garmin Connect as well as giving smart notifications on the move. Activity tracking counts steps, distance, pace, heart rate and calories burned indoors and out. It also records ground contact time balance, stride length, vertical ratio and more.

    A Good All Rounder For 10ks, Half Marathons and Marathons 

    We have been running with the Garmin 235 (its predecessor) for 4 years now and in fact, it is this model that is one of the more popular Garmin running watches amongst our peers and the athletes that we coach. My 235 has been going strong since January 2017 and continues to be reliable. It hasn’t lost charge. The only time it ever almost failed was during an ultra that took 13 hours. With only 11 hours charge, it meant charging on the go. This is a watch for those that aren’t running big distances and it won’t let you down. Definitely worth the price tag.

    It’s not to say that Garmin running watches are for everyone. We have some friends that run with TomTom, Apple watches, Fitbits and other brands. You will certainly find in a poll of a group of runners that the majority favour Garmin running watches though. 
    The most important thing is to decide what you will use the watch for. How much you will use it and does it have the technology you need or want. Is it within your budget?
