Age-Graded Running Calculator
Calculate age-graded percentage and age-adjusted race time using WMA 2023 tables across distances and sexes.
Your age on race day. Age grading adjusts your performance to account for the natural slowing that comes with age.

Calculate your age-graded percentage and age-adjusted time using the official World Masters Athletics (WMA) tables — compare performances fairly across ages, sexes, and distances. Enter your age, sex, race distance, race time, and surface (road or track). The calculator returns your age-graded percentage, a performance-level classification (from Recreational to World Class), the age-adjusted time that would place a 25-year-old in the equivalent percentile, plus the age factor and the open-class standard used in the calculation. Age grading is the fairest way to compare a 55-year-old parkrun regular to a 25-year-old club athlete.
AG% = (age_standard ÷ race_time) × 100 · age_graded_time = race_time × age_factor- AG%
- = Age-graded percentage — the core output
- age_standard
- = WMA open-class standard time scaled by your age factor
- race_time
- = Your actual finish time in seconds
- age_factor
- = Decimal factor (e.g., 0.8912) from the WMA table for your age, sex, and distance
- age_graded_time
- = Your time adjusted to equivalent open-class time
Worked example — 50-year-old man runs 22:15 at 5K (road)
- age_factor (M50, 5K road) = 0.8615
- open_standard (5K road) = 12:37 = 757 s
- age_standard = 757 ÷ 0.8615 = 878.7 s → 14:39
- race_time = 22:15 = 1335 s
- AG% = (878.7 ÷ 1335) × 100 = 65.8%
- age_graded_time = 1335 × 0.8615 = 1150 s → 19:10
- = 65.8% age-graded — 'Local Class' · equivalent open time 19:10
Formula F11 from site/03-globals.md §formulas. WMA 2023 tables (Alan Jones) are the current standard. Road, track, and cross-country have slightly different factor sets — this calculator uses the road and track tables per the surface toggle.

Remarkable Age-Graded Performances
Ed Whitlock — 2:54:48 marathon at 73
The Canadian masters runner's 2004 marathon at age 73 scores ~104% — the highest age-graded marathon time ever recorded. He became the first person over 70 to break three hours.
Gene Dykes — 2:54:23 marathon at 70
Dykes ran 2:54:23 at the 2018 Rotterdam Marathon at age 70 — an age-graded score of ~100% and the fastest marathon ever run by a 70-year-old under standard record conditions.
Sabra Harvey — 3:38:21 Boston at 70
Harvey's 2019 Boston Marathon at age 70 scored ~93%. She continued setting US age-group records into her 80s, becoming one of the highest-scoring female masters marathoners on record.
Jeannie Rice — 3:27:50 marathon at 70
Rice set the women's 70+ marathon record at 3:27:50 at the 2018 Berlin Marathon — age-graded ~95% and a redefinition of what's possible for women over 70 in endurance sport.
