Same route different distance
Jog with my wife this morning, same route, same time, side by side, but get a very different result.
I use Apple Watch 7 and my wife use Apple Watch 5. Both watch OS version is 9.0.
Both GPS on the watch tracks identical path in the map, no position jumping. But we have 1.5 km diference in distance.
How this is posibble? Anyone can explain?
Apple Watch Series 7
