Changes

The Garmin 920XT is an update to the [[Garmin 910XT]], adding many of the features from the [[Garmin 620]], while shrinking in size to become far less bulky than its predecessor. It's a large watch, but I found it comfortable even on my tiny wrists. Its [[GPS Accuracy]] is disappointing, and using the Russian GLONASS satellites makes this worse. However, the 920XT is the first of several watches in the Garmin range to support the revolutionary [[Connect IQ]]. This will allow the 920XT to run applicationapplications, much like a smartphone.* The 920XT is has a great device for casual runners. Its clear display, real buttons, and rich functionality that make it an attractive option if you can afford it. The [[Connect IQ]] extensibility adds some potential future proofing. * For marathon runners the 920XT lacks a critical feature; an accurate display simple evaluation of current pace. While a GPS watch, I look at how well it can answer some basic questions:* '''How far did I donrun?'''t expect This is the most casual runners will be as concerned by the lack of accurate current pacebasic question, this is critical to many marathon training programsand sadly, and to effective marathon pacing strategy. The only way I found of getting accurate current pace is to use the older 920XT has rather middling [[Garmin 610GPS Accuracy]], [[Garmin 310XT]]and while firmware updates might improve this slightly, or [[Garmin 910XT]] with a [[Footpod]]. (Connect IQ may change this in I doubt it will get close to the future.)* For ultramarathon running the battery life accuracy of the 920XT makes it a strong candidate. See [[Shoes#Watches for Ultrarunning| Watches for UltrarunningPolar V800]] for more details. =GPS Accuracy=The [[GPS Accuracy]] for the 920XT is middling; it's not the worst I've seen, but it's far from the best. Determining if it's good enough for you will depend on your usage. * The 920XT will give you a reasonable estimate of how far you've run and your overall average pace. The level of error will depend on your route; on straight lines it will be remarkably accurate (as will any other GPS watch), but on a twisty course like the one I run on, it is out by around 0.5 miles on a 20 mile run. That's enough to mess up your marathon training. If this is important to you, look for a more accurate watch. * Sadly GPS is not accurate enough to give '''How fast am I running?''' Knowing how fast you 're running can be a useful reading nice to know, or it can be vital for your training or race performance. Because of the nature of GPS, watches that rely on GPS signal alone tend to have serious problems with current pace. For that you need Sadly, the 920XT does not support the older display of current [[Garmin 610Pace from a Footpod]]while getting all other data from GPS. However, I'm hopeful Garmin will add this in future firmware like they did to the Epix.* '''Where am I? '''The 920XT does not have full color maps, but you can download a course, and it will give directions back to the start. * '''What's my cadence? '''[[Garmin 310XTCadence]]''' '''is one of the most critical and often overlooked aspects of running. If you get your Cadence right, or many other things naturally fall into place. Not only does the 920XT get [[Garmin 910XTCadence]] with from a [[Footpod]]. Those devices , it will allow you to also get your current pace it from the footpod while using GPS Garmin Run Heart Rate monitor. There is also support for everything else. Of courseCadence from the internal accelerometer, itthough I find that's quite likely that [[Connect IQ]] will allow this to be added to the 920XTnot as accurate. The Cadence alerts are especially useful for keeping you on track. * I've tested For ultramarathon running the battery life of the 920XT with and without GLONASS enabled, and surprisingly the accuracy is worse with GLONASSmakes it a strong candidate. In theory, GLONASS (the Russian equivalent to GPS) should improve accuracy, but that does not appear If you hope to be still moving during the case.If you want better [[GPS AccuracySecond Dawn]] than , the 920XT, then the might be for you. See [[Polar V800Shoes#Watches for Ultrarunning| Watches for Ultrarunning]] is by far the best I've testedfor more details.
