Just set up my edge 500 with gcs10 sensor on my bike,i set up my wheel measurement which is 700x25, to 2105 the garmin advised setting, cadence is ok but, speed and distance is to high, can someone tell me what i'm doing wrong.

It won't be wrong. Don't forget resistance might not be the same so you use a bigger gear for resistance than you would on the road.
