Anybody use their Apple Watch solely for running? How is the GPS and accuracy of the readings, etc.? And any comment on whether the 44ml size is too big for just running?
I'm considering Series 4 to replace an aging Garmin GPS watch. I'm not an iPhone user so it'd be solely for running and activities.
If you do not have an iPhone, then this is not the watch for you.
In terms of running data, if you did buy the Apple Watch, you could only see your pace and heart rate data while you were running. Once the run was over, it couldn't be uploaded to anywhere, or retrospectively accessed. These features require an iPhone to download the data to. This data can then be accessed from the Activity app in the iPhone.
I have a Garmin 735 and an Apple Watch S3. When I go running, I wear both. I wear my Apple Watch as it's my every day watch, and I want to close my rings, but I use my Garmin for my training.
On the Garmin, I use the interval training features, and it provides more metrics for each run. I also like that the run data can be uploaded to Strava, as well as being accessed on my iPhone. Apple Watch's data can't be uploaded anywhere.
These watches were a similar price when I got them (the Garmin has got cheaper since). Side by side, the Apple Watch is by far the better product. It looks, and feels and behaves in a superior way in every respect. It just does more, and does it better. But when it comes to running, the Garmin's specialist area, the Garmin is better at the moment, although only for the reasons I have given.
