First time? Userscript basics and installation steps

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:
  2. Click the Install button above for this script.
  3. Click “Install” when prompted by your userscript manager.

Bookmarklet

A bookmarklet is a bookmark whose URL is JavaScript. Use it on browsers that support bookmarks but not userscript managers.

Drag this link to your bookmarks bar:
