Garmin Connect activity backup tool
===================================
``garminbackup.py`` is a program that downloads activities for a
given [Garmin Connect](http://connect.garmin.com/) account and stores
them in a backup directory locally on the user's computer. The first time
the program is run, it will download *all* activities. After that, it will
do incremental backups of your account. That is, the script will only download
activities that haven't already been downloaded to the backup directory.

The library contains a simple utility program, ``get_activity.py`` for
downloading a single Garmin Connect activity. Run ``./get_activity.py --help``
for more details.

The library also contains a ``garminclient`` module that could be used by third-party
projects that need to communicate over the Garmin Connect API. See the
Library Import section below for more details.


Prerequisites
=============
The instructions below for running the program (or importing the module)
assumes that you have Python 2.7 or Python 3+,
[pip](http://pip.readthedocs.org/en/latest/installing.html), and
[virtualenv](http://virtualenv.readthedocs.org/en/latest/virtualenv.html#installation)
(not required with Python 3) installed.

It also assumes that you have registered an account at
[Garmin Connect](http://connect.garmin.com/).


Getting started
===============
Create and activate a new virtual environment to create an isolated development
environment (that contains the required dependencies and nothing else).

    # using Python 2
    virtualenv venv.garminexport

    # using Python 3
    python -m venv venv.garminexport

Activate the virtual environment

    . venv.garminexport/bin/activate

Install the required dependencies in this virtual environment:

    pip install -r requirements.txt



Running
=======
The backup program is run as follows (use the ``--help`` flag for a full list
of available options):

    ./garminbackup.py --backup-dir=activities <username or email>

Once started, the program will prompt you for your account password and then
log in to your Garmin Connect account to download activities to the specified
backup directory on your machine. The program will only download activities
that aren't already in the backup directory.

Activities can be exported in any of the formats outlined below. Note that
by default, the program downloads all formats for every activity. Use the
``--format`` option to narrow the selection.

Supported export formats:


  -   ``gpx``: activity GPX file (XML).

      [GPX](https://en.wikipedia.org/wiki/GPS_Exchange_Format) is an open
      format, mainly for storing GPS routes/tracks. It does support extensions
      and Garmin appears to annotate the GPS data with, for example, heart-rate
      and cadence, when available on your device.

  -   ``tcx``: an activity TCX file (XML).
      *Note: a ``.tcx`` file may not always be possible to export, for example
      if an activity was uploaded in gpx format. In that case, Garmin won't try
      to synthesize a tcx file.*

      [TCX](https://en.wikipedia.org/wiki/Training_Center_XML) (Training Center
      XML) is Garmin's own XML format. It is, essentially, an extension of GPX
      which includes more metrics and divides the GPS track into "laps" as
      recorded by your device (with "lap summaries" for each metric).

  -   ``fit``: activity FIT file (binary format).
      *Note: a ``.fit`` file may not always be possible to export, for example
      if an activity was entered manually rather than imported from a Garmin device.*

      The [FIT](https://www.thisisant.com/resources/fit/) format is the "raw
      data type" stored in your Garmin device and should contain all metrics
      your device is capable of tracking (GPS, heart rate, cadence, etc). It's a
      binary format, so tools are needed to read its content.

  -   ``json_summary``: activity summary file (JSON).

      Provides summary data for an activity. Seems to lack a formal schema and
      should not be counted on as a stable data format (it may change at any
      time). Only included since it *may* contain additional data that could be
      useful for developers of analysis tools.

  -   ``json_details``: activity details file (JSON).

      Provides detailed activity data in a JSON format. Seems to lack a formal
      schema and should not be counted on as a stable data format (it may change
      at any time). Only included since it *may* contain additional data that
      could be useful for developers of analysis tools.

All files are written to the same directory (``activities/`` by default).
Each activity file is prefixed by its upload timestamp and its activity id.



Library import
==============
To install the development version of this library in your local Python
environment, run:

  `pip install -e git://github.com/petergardfjall/garminexport.git#egg=garminexport`

If you prefer to use a `requirements.txt` file, add the following line
to your list of dependencies:

  `-e git://github.com/petergardfjall/garminexport.git#egg=garminexport`

and run pip with you dependency file as input:

  `pip install -r requirements.txt`
