Out with the old Garmin and in with the new!
5 Stars
Out with the old Garmin and in with the new!
BUY THIS WATCH! At the start of the quarantine, I decided to take my physical fitness a bit more seriously(again). Instead of dusting off my old Garmin Fenix 5, I decided to take a look at what is the latest and greatest on the market. My old watch was big and chunky and I hardly understood any of the features that it had. The Grit X has so many easy to understand features that I have been using since I put it on. The highlights so far:1) The GPS is rock solid, even going in/out of tunnels it still keeps track of pace/location etc.2) Battery life is outstanding - I have had it for five days already using it for about 4 hours and still have 50% battery.3) Navigation options - I love the options of adding Komoot/Strava Live segments to the watch - I don't have to worry about getting lost on some of my longer runs4) DETAILS! - On one run I was able to get HR, pace, distance, power, cadence, Hill Splitter (just to name a few). For the calories burned, you are able to see a breakdown of Carbs/Protein/Fat to help better understand recovery.The wrist based HR was spot on which was a relief and was consistent throughout my runs.Still looking forward to unlocking more on this watch, but it has definitely been a big motivator so far!
