Today, I ran a 16 mile trail run. At the end of the run, the Grit X showed that I ran 4.93 miles. It was failing in the first mile. I had good GPS reception, so I have no idea why this would happen. The device actually did track the entire route, heart rate, elevation changes, etc., but the distance and pace were completely wrong. This is the second run in three runs where the device has failed. I ended up tracking today's run on my iPhone, and it had no problem tracking.
The other night, I left the device to charge all night. When I woke up, the Polar Flow app and the device were showing that I hit 503% of my activity goal. Again, it was on the charger all night. When I reviewed the heart rate data, it was fluctuating all over the place between 120 bpm and 175 bpm all night long.
I did reach out to Polar on both issues, but I have not heard back from them. However, I've been running for almost a decade and a half, and I've used many GPS units. I've never had one fail so badly. It is not a good sign for this product. I need my devices to do the bare minimum, at least: track my route, distance, heart rate, and pace. If you can't do that with an almost $500 device (with tax), it is a complete fail. Possibly Polar can fix it, but how could they ship a device this flawed to begin with? Maybe this is a defective one. I don't know, and I don't have time to figure it out. It's very disappointing, but this device is being returned.
UPDATE: It has been three weeks, and Polar still have not responded to my two support requests. I've checked my Junk folder and anywhere else the email could end up. They have not responded. I understand we are living through a global pandemic, so maybe they are short-staffed. But Polar decided to release this device in May, in the middle of the pandemic, so they should have support available (working from home, I hope) for this brand new device. But they do not.
I'm not sure why there are so many positive reviews for this device when my experience was so bad. However, if you plug this Amazon product page URL into the website fakespot dot com, you'll see that it gets a low rating (a "D" at the time of this writing) in regards to legitimate reviews. So, if you are still interested in this device, be prepared to be frustrated. But more importantly, check the return policy and order it. I don't recommend it, but maybe you will have a better experience. My experience was very bad. It was the worst device I have ever tried in my 12 years of running long distances and mountain biking on road and trails (mostly trails).

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 runs
4) 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!

My priorities are:
1. Accurate GPS tracking and elevation
2. Battery Life (minimum 40 hours activity tracking)
3. Accurate Heart Rate
4. Lightweight & Durable
The Grit X excels in all of these categories. Its wrist based heart rate is the best I have experienced, and is tightly aligned with my chest strap measurements. The GPS tracking and elevation was flawless even when running in the Boulder foothills where many GPS units struggle due to the proximity to steep slabs and cliff faces. Battery life has proven to be excellent, and it is much lighter than all of its competitors with similar battery life. It is light enough that you do not experience any wrist bruising when riding technical mountain bike trails, yet durable enough to not be concerned about taking it on a fourth or fifth class scramble.
When you combine this with all of the standard Polar Heart Rate features, Hill Splitter, Fueling Reminders and Komoot Navigation support features, it is truly the product segment leader. You will be extremely pleased with your purchase of the Polar Grit X!

Aesthetically it's a great piece. I've taken to wearing it all the time, and the battery life is great. Once a week charge and I'm good to go.
One of the challenges I face with my two preferred sports is that Crossfit is very glycolytic (carb) intensive, and peak bagging is much more oxidative. Balancing these two nutrition demands for different training days and events is hard. I've been playing with the Fuelwise feature on the watch and it's really insightful.
With the current state of the world, I haven't been able to put the hillsplitter feature to the test yet, but I'm looking forward to tracking performance on hill repeats as well as long climbs.
It has all the features of my Polar Vantage that have been great for my training...with the added outdoor features as well. And it's a Polar, so the HR monitoring is the best I've found.
I'm looking forward to this year's training and results and the additional insights gleaned from my new Polar Grit X.
