So, this can help you.
This is a tool to convert files exported with GS-Sport Training Gym Pro (bundled with the GB-580P) to GPX format understandable by Strava.
The resulting file includes:
- Heart Rate data
- Cadence data
I use this computer to track my rides and upload it to Strava, which gives a good set of analisys on every workout.
1- Export your training from menu Main -> Export Activity
2- Keep the date in "Track Name"
3- Click OK and save
4- Open file
5- Click on "Parse" and save the file to your disk.
6- Now you can upload your file to Strava.
