The Garmin Epix is the top of Garmin's GPS watch line. The Epix has nearly all of the functionality of the [[Garmin 920XT]], plus support for full color maps. Having a good map display is great for both urban and wilderness runners when they're in unfamiliar surroundings. The Epix includes [[Connect IQ]] that allows it run applications, much like a smartphone. Its clear display, real buttons, touchscreen, map display and rich functionality make it one of the best watches if you can afford it and are okay with the poor GPS accuracy and its bulk. For a simple evaluation of a GPS watch, I look at how well it can answer some basic questions:
* '''How far did I run?''' This is the most basic question, and sadly, the Epix has rather poor [[GPS Accuracy]], and while firmware updates might improve this slightly, I doubt it will get close to the accuracy of the [[Polar V800]]. It looks like activating GLONAS and WAAS improves accuracy, it's still not great. How big a problem this is for you will depend on the type of course you're running, but if this is important to you, look for a more accurate watch.
* '''How fast am I running?''' Knowing how fast you're running can be a 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. Thankfully, the Epix is one of the few devices that will display current [[Pace from a From A Footpod]] while getting all other data from GPS.
* '''Where am I? '''The Epix has full color maps, the ability to download a course, and to give directions back to the start. This is as good as it gets.
* '''What's my cadence? '''[[Cadence]]''' '''is one of the most critical and often overlooked aspects of running. If you get your Cadence right, many other things naturally fall into place. Not only does the Epix get [[Cadence]] from a [[Footpod]], it will also get it from the Garmin Run Heart Rate monitor. There is also support for Cadence from the internal accelerometer, though I find that's not as accurate. The Cadence alerts are especially useful for keeping you on track.
