Garmin Forerunner 910XT Review For Ironman Triathletes

This latest offering from Garmin is a great way to track not just your heart-rate, but also Swim, Bike, and Run performance on many levels.

Hopefully this Garmin Forerunner 910XT Review For Ironman Triathletes will help you out if you are trying to decide if it will work for you or not.

It’s amazing just how far racing and training technology has evolved since the first ever Ironman Triathlon took place over 3 decades ago.


I remember the first time I ever strapped on a wrist heart rate monitor and how amazed I was those many years ago to see it displaying every beat of my heart. It seemed incredible to me to see just how it would increase so much with every hill I climbed on one of my Ironman training runs and how it would ease off on the downhills.

You have to remember that back in the late 70’s when I first started running and became a marathoner, you ran by feel and intuition and most of the time screwed everything up and hit the wall with a resounding thud at about the 20-mile-mark. In the Ironman in the mid-eighties it was happening to me about half-way through the 112-mile bike with still an entire marathon to go.

Now here is Garmin with a device that could well revolutionize the way the high tech Ironman trains.

In Garmin’s own words………..

On land, Forerunner 910XT offers many of the features of our advanced cycling computers and sport watches to accurately capture your time, distance, speed or pace. The 910XT is our first multisport device to incorporate a barometric altimeter for highly accurate elevation data, including ascent, descent and grade. Configurable data fields let you customize multiple training pages for each sport. Set up vibration alerts to give a silent nudge when you hit a split, when it’s time to take nutrition or if you need a little feedback to stay within range of your goals. With these high-level features and up to 20 hours of battery life, the 910XT is ideal for athletes training for ultras or iron distance.

For advanced training, the 910XT is compatible with ANT+™ sensors, including the optional speed/cadence sensor for cycling or premium heart rate monitor (included with some models). You can pair the 910XT with an existing ANT+ heart rate monitor or purchase as an accessory. Track your weight, body fat, body water and 6 other measurements when using the 910XT with the Tanita BC-1000 body composition scale. The readings are stored on Forerunner 910XT, then automatically sent to Garmin Connect when in range of your computer.


To me the swim functions are simply amazing. I really believe that most age-group Ironman triathletes have no idea just how much further than 2.4 miles they actually swim on race-day.

The 910XT tracks swim distance, efficiency, stroke count, pool lengths and your open water swim path.

I’m sure that in just about every Ironman I ever entered I most likely swam closer to 3 miles than 2.4 because I was all over the course and was nowhere near maintaining a straight line.

Have a look at what the Forerunner can do for your Ironman swim training and racing.

Forerunner 910XT is the only all-in-one device that provides detailed swim metrics and tracks distance, pace, elevation and heart rate1 for running and cycling. Designed for open water and pool swimming, Forerunner 910XT is water resistant to 50 meters. It’s our first multisport watch to offer extensive swim metrics, including swim distance, efficiency, stroke identification, stroke count and pool lengths.

Forerunner 910XT even captures the path you traveled so you can view it on a map later in Garmin Connect™. Just think how your open water swimming could improve if you could analyze your path and efficiency to this level.


A heart-rate monitor is great for helping triathletes maintain a consistent heart-rate by easing off on the down-hills and shifting into a bigger gear on the down-grades in order to take advantage of gravity.

But the Garmin Forerunner technology can do so much more for your Ironman bike training and racing.

Forerunner 910XT can track your cycling distance, speed and other metrics. The 910XT is our first multi-sport device to incorporate a barometric altimeter for highly accurate elevation data, including ascent, descent and grade.

For advanced training, the 910XT is compatible with ANT+™ sensors, including the optional speed/cadence sensor, heart rate monitor (included with some models) or power meter. It moves easily from wrist to bike with the optional quick release kit, making your transition between sports effortless.


Heart-rate monitor training is a great way for triathletes to teach their body to burn fat as opposed to glycogen for fuel and in the process enhance endurance.

However the Garmin Forerunner 910XT can take Ironman Triathlon run training and racing to a whole new level.

Forerunner 910XT delivers with advanced features like a vibration alert so you can get a silent nudge when you hit a split or it’s time to take nutrition.

Some models come with a premium heart rate monitor so you can keep an eye on your beats per minute and zone.


Whether you’re training or racing, every second counts, so the 910XT makes it easy and seamless to transition between sports. The auto multisport feature lets you switch sport modes with just 1 button press, so you don’t lose precious seconds in transition. The optional quick release mount allows you to move the 910XT easily from wrist to bike.

  1. I have just upgraded from the 305 to the 910.

    The Forerunner range is great to be sure, however, it is my experience with the 910 so far that:
    A) the open-water swim GPS tracking (distance, course) is inaccurate enough to be of almost no real value, other than a stopwatch, and to count your strokes. The open-water swims I have recorded even map me swimming through a dam wall onto dry land!
    B) there appears to be a problem with average pace when you are running – it fluctuates wildly between a pace I know I cannot run, and a pace I know I am not running (even though these problems do not appear when the data is loaded to GarminConnect etc – data smoothing?)

    • Thanks for your comment. These are certainly issues I would take up with Garmin. There could be technical things happening they would love to know about as the product is so new and really the athlete is the one is sure to give it the best test.

      Possibly it is an isolated event with your particular purchase.

      In any event you would think Garmin would also replace your Forerunner.

      Maybe we will get someone to post who has had a great experience with their Garmin Forerunner or perhaps more people who have had your problem.

      Stay tuned……would love to hear more about it either way.
