About Age Grading

Age Grading uses tables compiled by World Masters Athletics (WMA) to compare performances of runners at different ages. It allows a 50-year-old runner to compare their time fairly against a 25-year-old runner.

Interpreting your score:

  • 100% +: Approximate World Record Level
  • 90-99%: World Class
  • 80-89%: National Class
  • 70-79%: Regional Class
  • 60-69%: Local Competitive Class
