The Garmin Forerunner series blends features from the best fitness trackers with all the features you expect from running watches. The $449.99 Garmin Forerunner 735XT, one of the newest in the family, is a 24/7 activity and sleep tracker with continuous heart rate monitoring, GPS, push notifications, and special features for triathletes. It's expensive, but it manages to be both lightweight and achieve absolutely terrific battery life. If you're a triathlete in search of a new fitness tracker, the Garmin Forerunner 735XT is a clear Editors' Choice. If you aren't already signed up to compete in a tri, the 735XT is probably overkill both in terms of features and on your wallet. I'd recommend instead the Garmin Vivoactive, or the Garmin Vivoactive HR if you feel strongly about having wrist-based heart rate monitoring. They cost a lot less and have all the features needed for runners, swimmers, and bicyclists who don't need to do quick transitions. Price, Design, and Battery LifeWhe...

The Garmin Forerunner 735XT fitness tracker gives pertinent information to triathletes about their sports, including advice you don't often see, like recovery time. It's comprehensive and easy to use but will set you back a pretty penny.

There are smartwatches, there are running watches, there are fitness trackers, there are heart rate monitors, and there are watches for triathletes. The new Garmin Forerunner 735XT aims to be all of those things in a single device.

Can track running; swimming and biking; Very accurate location info; Comprehensive Garmin Connect app; Excellent battery life

Expensive; Heart rate could be more accurate

i bought this watch to track my exercise, esp., triathlon training. out door running and cycling features are very straightforward and easy to use. GPS signal is very good and accurate. indoor lap tracking feature blows my mind off.

The Garmin Forerunner 735XT is a hardcore fitness tracker designed for triathletes and those who become excited by the prospect of a Tough Mudder challenge. It can be bought as a standalone unit (￡360) or as a Tri Bundle (￡450), which includes Garmin's advanced HRM Tri and HRM Swim chest straps.

Robust design; Great multi-sport support; Good coaching and activity tracking

App is difficult to navigate; Not the best-looking watch around

The Garmin Forerunner 235 is one of my favorite running watches and for good reason: It has everything runners need to take their training to the next level. It's not ideal for multisport athletes, though.

Lightweight and waterproof, and has GPS for tracking a variety of sports and an optical heart-rate sensor; All-day activity tracking, interval training and phone notifications are helpful; There's a multisport mode to time triathlon transitions and easily switch sport profiles.

It's expensive; there's no altimeter for measuring ascent and descent; and battery life may not be long enough for a full Ironman triathlon

The Forerunner 735XT is an exceptional watch for serious triathletes, but there are better and cheaper alternatives for both dedicated runners and more casual athletes.

Lightweight and waterproof, and has GPS for tracking a variety of sports and an optical heart-rate sensor; All-day activity tracking, interval training and phone notifications are helpful; There's a multisport mode to time triathlon transitions and easily switch sport profiles; It's compatible with a wide-range of Garmin accessories.

Fitness is the new obsession that many hardware manufacturers wish to capitalise on with from wearables for counting steps and measuring sleep to watches meant for hardcore marathon runners.

This is a powerful training watch. However the design is very small for my usage. I would stay with the more expensive Fenix 3 HR over this one. You can also consider Polar m400 or Polar v800.

The best Garmin GPS I have used , super quick satellite finder , has all the features you will ever need and then some , I wear it all the time as a watch and personal activity tracker, press a couple of buttons and your into a run , cycle or swim .
