I have a Forunner50 that records just the heart rate over time. I downloaded it to Garmin Traing Center and Garmin Connect with the ANT agent with no problem.
If the HRM file is tcx you can import it manually to GTC and/or GC.
What I want to do is to import my training from Tacx Trainer Software where the files are saved as .HRM. How do I get the .HRM file into GC? Is there anyway to convert the .HRM file to .TCX?
This problem has now been fixed with Mathias Krallmann's excellent FIT file repair tool. This tool can be used to import .hrm, .tcx, or .fit files. Repairs can then be made if the file is corrupted.
The file can then be output into .fit or .tcx file formats.
I have now converted 15 .hrm files from Tacx Fortius/Tacx Training Software into .fit format. They have been successfully loaded into the following applications:
PC: Garmin Training Centre
Training Peaks WKO
Internet Garmin Connect
