This is a good high-end, triathlon running watch – now superseded by the 920XT. It has great design and is a fairly robust bit of hardware from the market’s leading supplier.
Positives: It’s a serious triathlon watch, ably supported by a plethora of Garmin ANT+ sensors and the openness of Garmin’s data ecosystem to other software companies.
Negatives: Instant/Current running pace is wrong. The speed at which you run is a fundamental thing for a runner to know (you need to buy a footpod). Altitude is flaky, altitude/climb data is wanted by many cyclists. There’s none of the smartphone notifications and in-depth activity tracking functionality offered by the newer 920XT. I got through 4 or 5 910XTs whilst under warranty. Don’t buy one second-hand unless under guarantee.
Comments: Despite this, I like the watch; from the looks of it, to the using of it. And I like the fact that I can use my other favourite supplier’s software. It has pretty much all the on-screen metrics that most of us need. Compared to the 920XT, the watch wasn’t as buggy for the stuff that I used it for. I like my gadgets and fiddling with them. If you want a watch that ‘just works all the time’ then think carefully.

Thanks for the review. My workhorse Garmin 305 needs a repair and I learned today that Garmin is no longer repairing or supporting that model. doing some comparisons.
you NEED a footpod for the 910xt for instant pace. look at 310xt as well – that’s good value.
Thanks.
I went through many many 305s. At the end, Garmin would not support it. I went third party– fixyourgps.com and they got it running again. Then I got a 910xt, and one of my kids lost the 305 at his first 5k.
I like the 910xt, but I’ve been injured and not running since about four months in to ownership. I’ve done thousands of miles on the bike with it, and as a bike computer its fine but needs a bigger screen — if I’d known I was about to become a bike-only athlete I wouldn’t have the 910. When the running injury passes, I’ll add a run cadence sensor — but I got in on the Stryd kickstarter, so I’ll add cadence & power that way instead of the garmin foot pod.
