About

parkrun Position Bingo Challenge tracks the unofficial position bingo challenge on a parkrunner’s all-results page (e.g. parkrunner A1965346).

Challenge rules

Each finish contributes the last two digits of the finish position (00–99). Results are read oldest-first. Every hit is recorded; the grid cell shows the first time that square was filled. Scanning stops once all 100 squares are filled.

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