Garmin Forerunner 910XT

Where to begin? The Forerunner 910xt is Garmin’s most complete and advanced GPS watch they’ve ever made! Primarily, it was created for triathletes, but anyone who runs, bikes, or swims will appreciate the numerous features built into this watch.

The 910xt has all of Garmin’s training aids: interval and advanced workouts, Virtual Partner, Courses, Virtual Racer (a new way to compete against past workouts or activities downloaded from Garmin Connect), auto pause, and vibration alerts. These make workouts easy to create and follow, varied, and fun — you’re unlikely to get bored with these training tools.

Additionally, the 910xt has common triathlete features: multi-sport, which allows quick transitions between activities; the quick-release mount that makes it easy to move the watch from wrist to handlebar; it remembers different bikes, eliminating the need to reprogram the watch when switching between bikes; and the screens are highly customizable, allowing you to see the exact training information you need mid-workout.

While swimming, the 910xt uses an accelerometer to track distance, measure speed, count swim strokes, and (when indoors) laps. This is a big advance for GPS watches which traditionally can’t measure swimming distance or speed as they lose GPS satellite connection under more than a few inches of water.


Continuing with the Forerunner 910xt’s features, it has a built-in barometric altimeter for more advanced elevation tracking. The battery lasts an amazing 20 hours while exercising. The 910xt also works with nearly every type of accessory available today including a heart rate monitor, foot pod, bike speed and cadence sensor, and a power meter.

Given all the hardware and features crammed into this watch, it’s surprising sleek and compact compared to similar GPS watches. The downsides to this watch are its complexity and high price — although these factors should be expected given the 910xt’s numerous features and accessory compatibility.


  • Superior features including swim tracking, Virtual Racer, and advanced workouts
  • 20 hour battery life in exercise mode
  • Supports many accessories like a heart rate monitor, quick-release mount, and power meter
  • For triathletes, this is one of the best GPS watches available on the market


  • Numerous features make this watch highly complex
  • While it’s sleek given everything it can do, smaller and lighter watches are available for those willing to sacrifice features


Don’t let the swim and bike features fool you, this is a great watch for experienced runners. It has the same training aids found in Garmin’s other high-end running watch, the Forerunner 610, including advanced workouts and Virtual Racer.


The Forerunner 910xt is compatible with both the bike speed and cadence sensor as well as a power meter. The quick-release mount also makes it easy to transition the watch from wrist to bike. Overall, this is a superb watch for cyclists who need a feature-rich watch.


The 910xt has common triathlete watch features like multi-sport, a quick-release mount, and custom bike settings. But it takes it a step further by tracking swimming distance, speed, and strokes. Overall, its running, cycling, and swim features make this an awesome GPS watch for triathletes.


The 910xt can measure swimming distance and speed; it can count swim strokes and laps.


With its long (20 hour) battery and barometric altimeter elevation tracking, the 910xt is a great watch for ultrarunners.


We like the Forerunner 910xt for hiking as the built-in barometric altimeter provides accurate elevation readings.

The optional strap extender lets skiers wear the watch around their jacket, rather than hidden under layers of clothing.
