Garmin has been famous for GPS watches that are suitable for use in events like triathlons and ultramarathons for quite some time. Their earlier versions of big, durable, waterproof training devices have become fixtures at events all over the globe, and the Forerunner 910XT is designed to be an updated version of the older, larger models. The 910XT is a very capable mulit-sports watch that has all the durability and features that any triathlete covets, but it’s also much less bulky and heavy than older models. While the case of the watch has been slimmed down, battery life has been improved at the same time, allowing athletes that participate in daylong events to depend on their 910XT until they finally break the tape.

Triathlons make incredible demands on the participants as well as their equipment, and the Garmin 910XT is up to the task for swimming, bicycling, and running. It’s a much more capable device than its predecessors when it enters the water. During training sessions, the accurate information it can supply about the distance you’ve traveled in the water and the amount of strokes it took you to do it can be invaluable for what is often the most grueling leg of the race. It’s also capable of measuring altitude, which can be very useful for extreme sports enthusiasts who need much more information than casual runners.

Garmin Forerunner 910XT GPS-Enabled Sport Watch with Heart Rate Monitor (Triathlon Bundle)

The Garmin 910XT is water resistant to over 150 feet, making it perfect for withstanding the rigors of the first leg of a triathlon. It tracks your distance, course, and number of strokes accurately, whether you’re inside in a pool or outdoors in open water. Many sports watches were unable to do much of anything during the swimming legs of multisport races, so the 910XT might allow you to improve one-third of your time more effectively than any other upgrade of your equipment. It’s even designed to let you keep the watch on your wrist while removing your wetsuit, which will save you precious seconds when you emerge from the water for the second leg of a triathlon, and might even save you from losing the watch altogether when you take if off to wrestle with your suit.

Transitioning From One Mode to the Next Has Never Been Easier

It’s easy to transition from one sport to another with the Garmin Forerunner 910XT. Press one button and your pre-programmed modes move on instantly to the next leg. The new barometric altimeter feature lets bikers and runners plan for steep grades instead of measuring all distances as the crow flies.

The Forerunner has programmable vibrating and audible alerts that can be used to inform you of an opportunity to take water or nourishment at specific intervals without having to keep all the data in your head and watch the time constantly.

Sensors Help Track Every Aspect of Your Race

The Forerunner 910XT integrates almost every form of popular ANT+ sensors for measuring things like footfalls, heart rate, and pedaling cadence. If you want a watch that will take you through a complex training regimen before a big event, the 910XT will closely track your weight, body fat, body water, and other important physiological metrics to keep you on track for race day. Whenever you’re within range of your computer, the 910XT will connect and download stored information so you can store in on your Garmin Connect account and keep track of it over time.


  • Very accurate measurement of location and distances
  • Waterproof housing makes it perfect for triathlon events
  • Can synch with footpods to give accurate cadence when running on a treadmill or pedaling a bicycle
  • Nicely backlit for night runs
  • Long battery life is great for ultra-marathoners and triathletes

  • Feels somewhat heavy, especially when swimming
  • Somewhat pricey
  • Swimming data stops when your arms are underwater

Final Verdict

Garmin Forerunner 910XT GPS-Enabled Sport Watch with Heart Rate Monitor

A watch specifically designed for triathletes and ultramarathoners has to be robust in construction, and it has to supply many more kinds of information than a simple running watch, and the Garmin 910XT really delivers. In some ways, the 910XT only competes with earlier versions of Garmin’s multisport watches.

Extreme athletes are fond of holding on to the earlier versions of this watch until they just won’t work anymore, and since the entire line of Garmin Forerunners has always been very reliable, people keep using their old watches for a long time.

The features of the 910XT might be enough to finally convince them to upgrade to a newer model. The increased functionality of this model when used in the water is probably enough on its own to have a measurable effect on the finishing times of a three-sport athlete, and anything that cuts down your time is likely to get used sooner than later.

The Garmin Forerunner 910XT is very highly rated by purchasers, with over 77 percent rating it as four stars or better. It’s not inexpensive, but users say it’s well worth the money they spent on it, so we can recommend it highly.
