Garmin Forerunner 735XT Triathlon Watch Review
The Garmin Forerunner 735XT delivers everything you could want from a triathlon watch and more. It is designed for elite athletes and people who are serious about their training progress, but it is suitable for the more casual exerciser too. It provides wrist-based heart rate monitoring, all-day activity tracking, and will take you from one sport to another with just the touch of a button.
The 735XT is more than just a running watch. It records your stride length, time balance, and more while running (although many of the running metrics features are only available when the watch is paired with a chest-based heart rate monitor), and will calculate your VO2 Max and predict race times based on your training history. It also offers lactate threshold estimates but, again, you will need an additional chest-based heart rate monitor for this which is not included in your £399 purchase of the watch.
The Forerunner 735XT is smart and will connect to your phone seamlessly through Bluetooth to provide notifications from your phone, automatic uploads to Garmin’s online community, and live tracking of your training. Syncing the watch with your phone is very easy and has worked every time without any issues for me. The GPS signal is very strong and the watch links up very quickly so that you can get on with your sport without having to wait around for your watch to be ready.
As a multisport watch, the 735XT is not as advanced as some of its siblings like the 935, but it still provides excellent support. It has a triathlon function so that you can time your transitions and switch between sports with just one press of a button. This feature also translates to duathlons and brick workouts for your training. If you only run, then this watch is perhaps too unnecessarily advanced for you, and you'd be better suited to a Forerunner 235.
The all-day activity tracking is a fantastic bonus feature on this advanced watch. The wrist-based heart rate monitor works all day while you’re wearing it and will provide you with a resting heart rate, recovery heart rate, and a graph of activity over the last 4 hours. This is really useful for heart-rate zone training, especially as the stats provided after your workout will tell you how long you were in each heart rate zone while you were active. The watch also provides you with an estimated VO2 max which is great for serious athletes. Part of the all-day activity tracking also includes step count which can be a great incentive to move more, especially on rest days. The watch also syncs with apps like MyFitnessPal so that your daily calorie burn is automatically taken into account when you track your food for the day.
A Closer Look
The watch itself is light at 41g and the watch face is not as big as some of the other Garmin watches like the 235 or 935, so it is better suited for all-day wear. It has a rubberised strap for comfort, although once you're super sweaty after a tough workout, you don’t really want to keep it on as it gets a bit uncomfortable. The various displays are user-friendly and although the watch has a lot of features, they’re easy to find so you don’t feel like you're missing out on useful training information.
The battery life of this watch could be better, especially as it’s designed to be used for triathlons; I wonder whether it could last a full-length Ironman event.
On the whole, I am so impressed by this watch. Garmin has found the perfect balance between the casual running watch and the advanced athlete's companion. It gives more than its cheaper counterpart the 235 and is more user-friendly than the more advanced 935. It is perfect for serious triathletes but can also comfortably be used by people who may just be getting into the sport or who just like to swim, bike, and run. It has the option of more advanced training stats if you really want to go into them while keeping the useful everyday information at the ready.
