Your question should have been: is RunGPS compatible with Sporttracks ?
the answer is yes, the steps are:
1) in RunGPS exports your workout in a csv fomat file
2) in Sporttracks:
a) make sure you have the cvs import module (normally it is standard, or you need to get the plugin)
b) in rungps the name of some columns is not correct: altitude should become elevation, the distance should become "distance (m) as rungps output the distance in meter and sporttracks by default assumes km !
c) once you have made the header modification of point b) above, just import the file in sporttracks
BUT there was one issue in Sporttracks 2: the timezone was not correctly interpreted when coming from csv files, I didn't tets it with Sporttracks 3.0 since I don't use RunGPS much anymore due to my HxM being not precised.
As far as I know the Zephyr is not compatible, but you could probably record your training with Run.GPS+Zephyr and then import the recorded data to SportTracks. Other users probably know more about this issue ...
I would like to use the Zephyr HxM and RunGPS but I use Sporttracks for logging and analysing my trainings. Is the Zephyr compatible with Sporttracks? Is it possible to import heart rate and cadence data in Sporttracks?
