So been testing the SE2 out for a couple of weeks as a replacement for my old Garmin Forerunner which is knackered. Sadly it’s just wrong.

I knew during my first run it was wrong, I could see my average pace, on an easy run it’s never below 6:10/km, I’ve been running 2/3 years every other day, I just know what my pace is, on Apple Watch an easy pace is between 5:30-5:55/km, I never run at that pace unless doing intervals or something.

Trying to figure this out the GPS doesn’t seem to be accurate, it rounds every corner by a good bit and I’m thinking this is how I’m getting a faster pace, so if the GPS isn’t right every other metric is gonna be wrong.



This was a short 4K run, I used both NRC to track and the Apple Watch, the NRC is definitely closer to what Garmin was, sadly the longer the run the more the drift and inaccuracy.

Anyone else experienced this??

This shows the GPS drift, I was on the road clear area

I've never used a Garmin, but I do use NRC, and I've noticed that the NRC app consistently registers less distance than Apple workout app. Like, the workout app will say I've gone a mile, and NRC will have the distance at 0.95 miles or something.

I just went on a walk and paid closer attention to the tracks using my AW8.

The accuracy was spot on, I would say, even identifying which side of the road I was on. But the soft line diagrams aren't wholly representative of the entire street. I'm assuming that you were not running down the middle of the road either. It would be interesting to see the satellite map overlay.

You’re on to something mate. The overlay is a hell of a lot more accurate, the line diagrams are wrong, they don’t give an accurate representation of the width of roads etc which makes the gps route look wrong, but the satellite view id say it’s almost perfect
