What app are you using to monitor your route? I haven't use built in app for a long time, but yesterday I tested it for cycling and my route in the Activity app was way off. But, when I imported the same workout into RunGap, the same route is displayed exactly right!It cuts all the corners and has me running through buildings and gardens and random straight bits. Gold stainless steel 44mm.
My 3 is nowhere near as accurate as my cheapo mk1 garmin vivoactiveDone 6 runs now and all of them the GPS trial is all over the place. Walking it seems to be more accurate.
No wrist-based heart rate monitor is a match for a chest strap at this point.My 3 is nowhere near as accurate as my cheapo mk1 garmin vivoactive
It was so bad I went for a run with both my Apple Watch and garmin with a chest strap
The Apple Watch read about 10 bpm higher than the garmin and the god tracking was crap compared to the garmin
Also if you really want a chest strap for monitoring your heart the Apple Watch can connect to those over Bluetooth.No wrist-based heart rate monitor is a match for a chest strap at this point.
Otherwise, I've run thousands of miles with my S3 watch, on routes I've run thousands of miles on with my Garmin's. The results are generally well within the acceptable variations for GPS tracking. Both are consistent to themselves from run to run - even in the heavily wooded valley trails that I frequent. I've run multiple certified road races with the S3 where it has been accurate to less that .1 mile - as good or better than my Garmin's.
I use ismoothrun and you can wait for a satellite lock before starting the clock.I'm having similar poor results with GPS accuracy while running the same course I run every morning with my new Apple Watch Series 4. It was pretty accurate on the first morning run, but now seems to be underestimating mileage so my 4.1 mile run is now a 3.9 mile run even though it's the identical course. As a result my pace has dropped by almost a minute. My previous watch was a Garmin Forerunner 935 and its GPS was always reliable. I've noticed there's no wait time for the GPS to lock on when you start a run. Maybe it's not locking on right away and that's causing the discrepancies.
Ismoothrun. To me, it has the best integration between the aw and the iPhone. The when you run with the iPhone, the AW is basically a second screen for the iPhone app. Uses the iPhones GPS so it saves battery.I always run with my iPhone too. Which iPhone app?
