Garmin Connect Workouts Tools

Python application

Command line tools for managing Garmin Connect workouts.

Features:

  • Target power is set according to Your current FTP.
  • All workouts under Your control stored as JSON files.
  • Easy to understand workout format, see examples below.
  • Workout parts like warm-up or cool-down are reusable.
  • The most important parameters (TSS, IF, NP) embedded in workout description field.

Installation

Requirements:

  • Python 3.x (doc)

Clone this repo:

$ git clone https://github.com/mkuthan/garmin-workouts.git

Use the venv command to create a virtual copy of the entire Python installation.:

$ cd garmin-workouts
$ python3 -m venv venv

Set your shell to use the venv paths for Python by activating the virtual environment:

$ source venv/bin/activate

Install dependencies:

$ pip3 install -r requirements.txt

Usage

First call to Garmin Connect takes some time to authenticate user. Once user is authenticated cookie jar is created with session cookies for further calls. It is required due to strict request limits for Garmin SSO service.

Import Workouts

Import workouts into Garmin Connect from definitions in YAML files. If the workout already exists it will be updated:

$ python -m garminworkouts -u [GARMIN_USERNAME] -p [GARMIN_PASSWORD] import --ftp [YOUR_FTP] 'sample_workouts/*.yaml'

Sample workout definition:

name: "Boring as hell but simple workout"

steps:
  - { power: 50, duration: "10:00" }
  - { power: 70, duration: "20:00" }
  - { duration: "5:00" }
  - { power: 70, duration: "20:00" }
  - { power: 50 }
  • Target power is defined as percent of FTP (provided as mandatory command line parameter). If the target power is not specified "No target" will be used for the workout step.
  • Target power may be defined as absolute value like: "150W", it could be useful in FTP ramp tests.
  • Duration is defined as HH:MM:SS (or MM:SS, or SS) format. If the duration is not specified "Lap Button Press" will be used to move into next workout step.

Reusing workout definitions:

name: "Boring as hell but simple workout"

steps:
  - !include inc/warmup.yaml
  - { power: 70, duration: "20:00" }
  - { duration: "5:00" }
  - { power: 70, duration: "20:00" }
  - !include inc/cooldown.yaml
  • !include is a custom YAML directive for including another file as a part of the workout.

Reusing workout steps:

name: "Boring as hell but simple workout"

steps:
  - !include inc/warmup.yaml
  - &INTERVAL { power: 70, duration: "20:00" }
  - { duration: "5:00" }
  - *INTERVAL
  - !include inc/cooldown.yaml
  • Thanks to YAML aliases, workout steps can be easily reused once defined.

Sample Over-Under workout:

name: "OverUnder 3x9"

steps:
  - !include inc/warmup.yaml
  - &INTERVAL
    - &UNDER { power: 95, duration: "2:00" }
    - &OVER { power: 105, duration: "1:00" }
    - *UNDER
    - *OVER
    - *UNDER
    - *OVER
    - { power: 50, duration: "3:00" }
  - *INTERVAL
  - *INTERVAL
  - !include inc/cooldown.yaml
  • All nested sections are mapped as repeated steps in Garmin Connect. First repeat for warmup, second repeat for main interval (repeated 3 times) and the last one for cooldown.

To import your workout from an xlsx file, construct a table in Excel that looks like this (making sure that all Excel cells are set to text and not to date or any other format):

Start End Duration
43 85 3:00
85 15:00
85 43 2:00

If your "start" and "end" power for a step differ, a ramp of 10 seconds steps will be created by default for the chosen duration. If more than 50 total steps are to be uploaded ramp's steps will get longer so that the total number of steps is under Garmin maximum value of 50. TIPS Do not use your TACX without the power cable as your Garmin will have a hard time controlling the trainer while changing from one step to the next. Turn off the tones in your Garmin. If you wish to give your values in W instead of % of your FTP:

Start End Duration
80W 160W 3:00
160W 15:00
160W 80W 2:00

You can then import as with the yaml files:

$ python -m garminworkouts -u [GARMIN_USERNAME] -p [GARMIN_PASSWORD] import --ftp [YOUR_FTP] my.workout.xlsx

This will generate a yaml file with the name my.workout.xlsx. The name of the workout will be "my.workout".

Export Workouts

Export all workouts from Garmin Connect into local directory as FIT files. This is the easiest way to synchronize all workouts with Garmin device:

$ python -m garminworkouts -u [GARMIN_USERNAME] -p [GARMIN_PASSWORD] export /mnt/GARMIN/NewFiles

List Workouts

Print summary for all workouts (workout identifier, workout name and description):

$ python -m garminworkouts -u [GARMIN_USERNAME] -p [GARMIN_PASSWORD] list
188952654 VO2MAX 5x4           FTP 214, TSS 80, NP 205, IF 0.96
