What is a userscript?

A userscript is a small piece of JavaScript that runs in your browser and enhances specific websites. These scripts work with parkrun event pages, parkrunner profile pages, and results pages, and can be used with any userscript manager including Userscripts, Tampermonkey, Violentmonkey, or any compatible browser extension.

Installation steps

1. Install a userscript manager for your browser:
   • Desktop: Userscripts (Safari), Tampermonkey (Chrome, Firefox, Edge, Opera), or Violentmonkey (Orion)
   • iOS: Userscripts (Safari) or Violentmonkey (Orion)
   • Android: Install Kiwi Browser, then install Tampermonkey or Violentmonkey from the Chrome Web Store.
2. Click the Install button above for this script.
3. Click “Install” when prompted by your userscript manager.

Mobile bookmarklet

On mobile browsers that let you edit bookmark URLs:

1. Copy the JavaScript code below to your clipboard.
2. Create a new bookmark for any page.
3. Edit the bookmark and replace its URL with the code you copied.
4. Navigate to the relevant parkrun page.
5. Select the bookmark to run the script.
