Take a moment and imagine your potential if you were able to use one computer for all three disciplines of triathlon. Imagine how much faster your transitions would be if you could simply touch a button to toggle between your swim and bike metrics. Stop imagining, the Garmin Forerunner 910XT HRMisn't a fantasy, it's already here. From the water to the road, the Forerunner 910XT will provide you with all of the valuable training and race data that you need in order to elevate your fitness and results.

Starting with the most necessary feature for the swim, the 910XT is water-resistant up to 50 meters in depth and is suitable for both open water and pools. And with the customizable display, you can view metrics like distance, efficiency, stroke identification, stroke count, and for indoor training, pool lengths. All of this data is available in real time, and for race recon and training, the path analyzation feature will prove invaluable in the war room. This metric allows you to capture your path for viewing in Garmin Connect afterwards. So, you can analyze your output, stroke by stroke, along the entire path of your swim.

Once you go through T1 and get into the saddle, you'll be able view your distance and speed. And with the 910XT's barometric altimeter, you can also view your degree of gradient, total ascent, and total descent. Even better, if you're training or racing with multiple systems in place, the 910XT is compatible with ANT+ sensors. So, you can share data with your CPU of choice, power meters, and even Garmin's new Vector pedal-based power meter system. Syncing with devices like these will further the importance of your metrics by allowing you to view your power output and cadence.

On the running segment, Garmin has provided metrics for distance and pace. You also have the ability to set vibration alerts in order to remind you to get some nutrition in or to hit a split. Additionally, you can sync the 910XT wirelessly to the provided ANT+ compatible, Garmin heart rate monitor for even more crucial data.

As for the features of the watch itself, the 910XT has a 20 hour battery life, and it displays anywhere from one to four data points at a time. For the fastest transitions in the Garmin line, the watch also features a multi-sport mode that's accessible with a single button. So, you can switch from Swim to Bike modes faster than you can get out of the water. For training, your data is all saved internally, and you can even utilize Garmin's new Virtual Racer program in real time. This feature lets you race against your personal bests, or even against another user account's time -- ie, your competition. The 910XT also comes equipped with the Virtual Partner program that works in a similar fashion to Racer, only the computer pits you against a static pace.

And once you're done with your race or training, you can upload your data to either your Mac or PC wirelessly. Additionally, once on your computer, you can chart your metrics, progress, and results online with Garmin Connect. Here, you can create customized workouts, set and view your routes, and view your friend's activities.

The Garmin Forerunner 910XT HRM is available in one size and in the color Black. Included with the watch is a Premium heart rate monitor, USB ANT Stick, AC charger, charging clip, expander strap, and manual.

Im not a Triathlete

  • Familiarity: I've put it through the wringer
  • Fit: True to size

I have had this watch for a few months now and am still learning different options for setting it up the way I want it. I wanted to spring for the 920xt, but the 910 does everything I want it to and more. It has had good battery life out of it and the ANT+ sync works well. Strap is comfortable and I hardly notice it even after 5 hours on the trail. Linked easily to HR monitor as well as speed/cadence sensors that I already owned. I would recommend this watch to any athlete who likes to dissect performance data.

Great watch; heart rate monitor broken

I love the watch itself (great GPS accuracy, just enough information to be useful while still maintaining a relatively low profile on my wrist). However, the advertised heart rate monitor came with a strap but no sensor attached to it, and also no English language manual. I was told that to get a new monitor I would have to return the entire device and get a new one, which seemed like too much of a hassle given how much time I had spent setting it up. So I'm giving this product a 2-star service experience although the watch itself deserves 4 or 5.

Still going strong

Great watch for multi sport although there are slimmer more streamlined options now. I've had it about two years and have used it for running and biking. I've taken it through 2 spartan races without issue (I wrap a wristband over the face to prevent scratches). The data recording is great, it integrates well with STRAVA and Garmin Connect. The only downfall is due to its age and that is lack of bluetooth connectivity. I knew this going in and there were no products on the market that had all of the 910xt features and bluetooth when I made my purchase. Moving forward, bluetooth connectivity in my mind would really enhance this product and is what I will look for when it is time for a replacement.

Very Reliable Partner

Purchased the product about two months ago and have used it exclusively for running and biking. Technically I have not had any issues and all the accessories, (e.g., bike speed/cadence, HR monitor, and quick connects) have connected and worked beautifully. I ran a 5k race in my first use and the GPS accuracy was right on the money. I have run several times after that and no disappointments - light years away from my old Polar!

Regarding the bike use, I took some time to get all the settings (e.g., display) the way I like them, but now it shows me everything I need during my rides (perhaps more than I'd ever need). The unit is big enough to display all the metrics and it's not bulky at all.

No swimming yet, but I think the unit works great overall. It does everything I need plus more!

Does it all

A really nice computer if you're into Tri stuff. Works well on the bike, in the pool, or pounding the pavement. Would be great to have more than 4 metrics on the screen while cycling, but definitely wouldn't want a bigger watch while running or swimming so I think it's a good compromise. Having the removable band makes it a bit more cumbersome to wear but nice to be able to click it onto a bike mount.
