Running race length adjustment when GPS underestimates by a few meters
I have done couple of running races lately where my Garmin 920xt show a slightly shorter distance i.e. 9.96 km for a 10 km race and 20090 m for a half marathon.
This is international races where the length is verified so I would like to have the possibility to adjust these to the official length. Maybe it should be allowed to adjust the recorded length by 1-2 % or so.
I know that the crop tool can be used to shorten the distance but not the other way.
(one can export the gpx from Garmin Connect, correct the length in a tool and then import it back but that is to many steps)
