I've read a few threads on here but noone seems to have a solution.
I track a normal run route of 3.2km every week, with consistently getting the same result from my Lily 2 watch connected to the GPS of my samsung phone.
My husband just ran the exact same route at 2.8km with his Garmin forerunner. Google maps confirms his distance is accurate and mine is 400m off.
How is this even possible when it should be based off map data, and what can I do to fix it other than getting a better watch?
