This script was develop with the very specific purpose of merging HeartRate data from one .tcx-file into another .tcx-file.

However... The class ParseTcx.py is a generic class that can parse any .tcx-file. This can be very useful if one would like to use Python to analyze the data in one way or another.

I use a Tacx Bushido trainer and a Garmin 920XT. I get almost all the data collected in the files that are exported from the Tacx Cycling App, but since my HeartRate monitor only connects to my watch (Garmin 920XT) a need to merge that data into the file from the Tacx Cycling App.

Edit: Config.py

# Add .tcx file from the Tacx trainer and your Garmin device to a new row
...
config['2016-02-18'] = Session('BRH-16-Full course(6).tcx', 'activity_1055207164.tcx')
config['2016-02-09'] = Session('BRH - 17 - Full course(1).tcx', 'activity_1045149528.tcx')
...

Edit: run.py

# 1) Add current date to MergeTcx('date')
# 2) Run run.py

merged = MergeTcx('2016-02-01')
tcx = ParseTcx(merged.file_name)
tcx.parse()
tcx.plot_signal('HeartRateBpm')

This will give you a new file 2016-02-01_merged.txt with to original .tcx from the trainer merged with HeartBeatData from your Garmin device.
