GPS tend to work on movement between two points, so aren't so hot on trainers
IIRC ( and I am happy to be corrected) the Garmin series can measure speed, cadence and heart rate on a trainer if you switch the GPS off
You can then load up this data and display as a function of time. Distance will always however be zero
Close enough, but the distance is recorded on the Garmin using the cadence/speed sensor, so any turbo trainer rides give you all the same results as a real ride with the exception of showing you your journey on a map.
