One quick tip: when starting a new project, it is sometimes is useful to
see if others have done the same thing and use their approach to guide
yours. In your case, googling "Garmin Forerunner xml python" results in
this blog post which is recent enough that it should be helpful.

Note that coming up with good phrases for google to help you with a
programming task is a skill that you get better at with time.

Welcome to Python! ^-^
