An analysis of 11.2 million parkrun results exploring age grading accuracy and proposing the Terrain-Adjusted Grade (TAG) – a new metric that accounts for course difficulty.
Adding course difficulty factors for the 112 parkrun Ireland courses to the 27 Northern Ireland courses already in the UK dataset — completing TAG coverage across the whole island using 19,401 shared runners as the calibration bridge.
Extending Terrain-Adjusted Grade (TAG) course difficulty factors to Australian parkrun courses.
Extending Terrain-Adjusted Grade (TAG) course difficulty factors to New Zealand parkrun courses.
Testing TAG predictions against 993 club runners at Wilmslow and Brentwood — accurate to ±5 minutes for 47% of runners, with competitive athletes consistently beating predictions.
Validating TAG marathon predictions against 560 runners at Chester 2025 — 91% within ±20 minutes whether predicting from parkrun or half marathon, showing the formula scales correctly with distance.
