When going round a MTB circuit, I'd like to use the lap detection feature of rungps.
I have set a placemark at the start/finish line of the track and make it navigate to this point. This works fine, as every passage triggers a new lap.
However, the circuit has another passage which runs close to the finish line (about 30-40m) and a new lap is detected at this point as well. Needless to say, this is not what I want.
The track can be seen at http://www.gps-sport.net/trainings/cycling_573280
The circuit is located in the west. Laps 5, 7, 9 and 11 are the correct ones.
Is it possible to lower the threshold distance for detecting a new lap, in some way?
