About
parkrun Volunteer Days Display shows each finisher’s volunteer credit count on results pages, for celebration — without inventing run-to-volunteer ratios (e.g. Fountains Abbey latest results).
What you see
Where the results table exposes volunteer credits (data-vols greater than zero), the script adds text such as 3 volunteer credits in the detailed name cell.
It also adds sort by volunteer credits (ascending and descending) to the page’s existing sort control and, when present, the responsive sort dialog.

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