A 55-year-old running a 22:00 5K and a 30-year-old running the same time are not the same performance. Age grading puts them on one scale. Coaches use it to track fitness across decades. Race directors use it to award masters prizes. Parkrun publishes it on every results page. This calculator gives you the same number in a few seconds.
Pick your unit system, enter four values, and read the score. The whole process takes under 15 seconds once your race result is in front of you.
Choose kilometres or miles from the unit system selector. This changes distance and pace labels only. It does not change the underlying calculation.
Enter your age in years. The tool accepts whole numbers from 5 to 100.
Select your sex. Male and female use different world-record standards and age factors.
Pick the race distance from the dropdown or tap a preset (5K, 10K, Half, Marathon).
Break your finish time into hours, minutes, and seconds. A 1:45:30 half marathon goes in as hours=1, minutes=45, seconds=30.
Read the age-graded score in the hero panel. Anything above 60% means you’re faster than a recreational runner for your age.
Check the age-graded time tile to see your equivalent open-division performance.
Scroll to the reference tables to see how your score compares across age groups and performance levels.
Age grading divides your actual time by an age-standard time, then expresses the result as a percentage. The age-standard is the estimated world-best time for your exact age, sex, and distance.
Formula: Age-Graded Score = (Age Standard ÷ Actual Time) × 100
The age standard comes from two components: an open standard (the world-record time for a young adult at that distance) multiplied by an age factor (a multiplier that grows as you get older, because the expected best time gets slower).
Formula: Age Standard = Open Standard × Age Factor
Formula: Age-Graded Time = Actual Time × Age Factor
The age-graded time is the reverse operation. It tells you what your current fitness would produce if you were in the open division (roughly age 20–34). Multiply your actual time by your age factor and you get that equivalent.
The age factor table is the engine here. A 30-year-old male has a factor of 1.00 for most distances. A 60-year-old male has a factor around 1.33. That means a 60-year-old’s 5K time gets multiplied by 1.33 before it’s compared against the open standard. The result: a slower raw time can score higher than a faster raw time from a younger runner.
A WMA age-graded score is a percentage; an age-graded time is a clock time. The score tells you where you rank relative to your age group’s best. The time tells you what you’d run in the open division.
| Dimension | WMA Age-Graded Score | Age-Graded Time |
|---|---|---|
| Output format | Percentage (e.g., 69.7%) | Clock time (e.g., 56:41) |
| What it measures | Performance quality relative to age-group best | Equivalent open-division performance |
| Best used for | Comparing runners across ages and sexes | Tracking personal fitness across decades |
| Typical range | 0–100%+ | Same distance as input |
| How it’s calculated | (Age standard ÷ actual time) × 100 | Actual time × age factor |
| Affected by distance | Yes; each distance has its own standard | Yes; the factor table is distance-specific |
| Published by parkrun | Yes; on every results page | No; not published |
| Used for race awards | Yes; USATF masters championships use it | Rarely; occasional age-graded time bonuses |
The score wins when you’re comparing two runners. If a 42-year-old woman runs a 22:00 5K and a 28-year-old man runs a 19:30 5K, the score tells you they’re equal (both 65.7% on 2026 standards). Raw times say the man won. The score says it’s a tie.
The graded time wins when you’re tracking yourself. A runner who used to run 18:00 at 25 and now runs 20:30 at 45 can check the graded time. If the graded time is around 18:15, their fitness has barely moved. That’s more motivating and more honest than staring at a slower raw number.
Your score is driven by three inputs (age, sex, distance) and one output (time). The formula is deterministic: same inputs always produce the same score. What varies is how those inputs interact.
Age drives the factor table. A 35-year-old and a 70-year-old running the same 5K time get very different scores. The 70-year-old scores roughly 60% higher because the age standard is larger.
Sex determines the open standard. Male and female open standards differ by roughly 8–10% across road distances. The age factors are also slightly different, especially above age 70.
Distance changes the standard. The open standard grows non-linearly with distance. A 5K standard is 769 seconds; a marathon standard is 7,235 seconds. That’s a 9.4× jump for an 8.4× distance increase.
Course type isn’t in the formula. The calculator assumes flat, road-legal conditions. A hilly 10K produces a slower time that grades lower than the same effort on a flat course.
Weather isn’t in the formula. Heat, wind, and rain slow runners down without any corresponding adjustment in the age standard. A 25:00 5K in 32°C heat scores the same as a 25:00 in 12°C.
Training volume and consistency affect where you fall on the curve. The WMA tables are built from world-best performances, not average runners. A 60% score means you’re at 60% of the best time ever recorded for your age. Most recreational runners sit between 40% and 60%.
Altitude and air quality are unadjusted. A race at 1,500m elevation produces times that grade 3–5% lower than sea-level equivalents.
Weight and body composition influence running economy. The age factor tables don’t adjust for these variables; they’re built from elite performances where body composition is already optimized.
Anything above 60% is above recreational level. Above 70% is regional class, above 80% is national class, and above 90% is world class. Most regular runners score between 50% and 70%. A score of 100% means you matched the estimated world-best for your age and distance.
The calculator divides your actual finish time by an age-standard time, then multiplies by 100. The age standard is the open-division world-record time for your distance and sex, multiplied by an age factor that grows as you get older. That’s the whole formula.
It’s your finish time multiplied by your age factor. The result is what you’d theoretically run in the open division (roughly age 20–34) at your current fitness level. A 50-year-old who runs a 45:00 10K might have a graded time around 39:30.
No. Age grading adjusts an existing result for age and sex. Race time prediction estimates what you could run at a different distance. They’re different tools for different questions.
A score of 90% or higher is world class. A score of 100% means you matched or exceeded the estimated world-best for your age. Above 100% typically means a record-level performance.
Yes. That’s one of the main uses. A 42-year-old female running a 22:00 5K and a 28-year-old male running 19:30 both score roughly 65.7% on 2026 standards. Age grading puts them on one scale.
Different calculators use different table revisions. The WMA updated its age factors in 2023, and open standards change when world records fall. A 75% score on 2010 tables might be 72% on 2025 tables.
Not properly. Age grading requires a standard distance with a defined open standard. This calculator supports nine preset distances. For other distances, a pace calculator or race predictor is more appropriate.
Around 1.33 for most road distances. That means a 60-year-old male’s actual time is multiplied by 1.33 before it’s compared against the open standard. A 30-year-old male has a factor of 1.00.
The tables have been revised in 1989, 1994, 2003, 2006, 2010, 2015, and 2023. Open standards update whenever a relevant world record falls. The 2025 WMA/USATF road standards are the current reference for this tool.
They’re the same system. Parkrun uses WMA-based tables to publish an age-grade percentage on every results page. The numbers should match closely, though parkrun may lag the latest table revision.
Yes. If your performance exceeds the estimated world-best for your age, the score rises above 100%. This usually means a world record has been broken since the standards were last updated.
