is there a way to change activity category in a large batch?

Original (outdated) comment:

Touch0Gray What activity type do you need? I've got a script to change all your activities to "Running" but it can be adapted for other activity types, too. You need a PC or a Mac (or Linux).

1. Get Python 3 (Windows/Mac/Linux): https://www.python.org/

2. Download the gc-running.py script: Go to [LINK REMOVED] and click Download.
   (See edit below for the latest version of the script)

3. Double-click the script (or launch from terminal/command prompt)

The script will prompt you for your username, password, and date range for activities.

Currently it only supports changing your activity type to running. Let me know if you need something else.

EDIT: (latest comment) (2021-03-31)

I've posted a new version of the script (now called gc-activity-type.py): https://pastebin.com/ZZW7qnFX

New features:
1) Filter by existing activity type, activity type ID or activity parent type ID (use the --help option to see available options)

2) Select new activity type, activity type ID and activity parent type ID using command line options (otherwise you will be prompted)

3) Preview changes using --dry-run option. Matched activities are listed during a dry run, along with their activity type (e.g. "running"),  activity type ID (e.g. 1), and activity parent type ID (e.g. 18)  So if you want to find out the type name, type id and parent ID for inline skating, you can create a new inline skating activity manually, and use the "--dry-run" option to list the information that you'll need to change other activities to inline skating.

4) Fix SSL error that some users were experiencing

5) Fix payment required error

e.g. To run the script from the command line and see available options:

python3 gc-activity-type.py --help

(dry run and matching/filtering activities by type are only available as command line options.)
