I've been playing around with Strava for a little while now and it has been a frustration to me to be unable to properly record on there the data from my VeloTron (or CompuTrainer) rides but I now think I've cracked it.
The key to the problem has been the requirement to convert files into a format understood by Strava, the files therefore need to be either .gps, .tcx or .fit files. A VeloTron session results in a file which is probably going to be a .txt file having been generated by the auto-export function of VTCS, though .3dp files or .cdf files may also be produced depending on which package is in use on the VeloTron or Computrainer at the time.
I use TrainingPeaks WKO+ to store and manipulate my data and this package accepts all the files that might be generated by any of the RacerMate packages. Once the files from the VeloTron or CompuTrainer are imported into WKO+ they are stored as .wko files. The requirement therefore was to convert from .wko to ideally .tcx to import into Strava.
That's where a very clever (and free) package called Golden Cheetah comes in. You need to use v3 to do this (it runs on Windows or Mac machines), you can then import (in batches if you wish) .wko files into Golden Cheetah which is great. Golden Cheetah then allows you to export files (again in batches if you wish) to .tcx format and they can then be uploaded to Strava, job done!
This all sounds rather long winded but is in fact very quick and easy once you have your head round the steps required and it does mean that you can store and share all your stuff from your CompuTrainer or VeloTron on Strava should you wish to do so. Golden Cheetah does offer a direct upload to Strava feature but in my experience at the time of writing if this is used the data does then not display correctly on Strava once uploaded, it works far better using the export to .tcx option and the files can also then be uploaded in batches via email to Strava.
I am again indebted to my friend Mark Liversedge one of the Golden Cheetah development team for his time and invaluable assistance, the man has a brain the size of a planet.
