During walking activities with GPS active I see that the distance recorded is very much differing from what I expected. Checking with another GPS app on the same walk proves this, measured with Guru maps and expected from my walking guide is 18km, however Connect shows 21.53km.
Recovering the number of steps (22400) and the personal setup of steplength 0.80m should also result in 18km.
What can I do to correct this?
I am on iPhone 13 and latest iOS
Thanks, Frans
