- This calculator uses the age-graded tables compiled by the World Masters Association (WMA), formally the World Association of Veteran Athletes (WAVA) -
JAVA script by John Soul

The Age-Grade Calculator is used to calculate your age-graded performance from your actual performance. This data can then be used to compare your performance with athletes of different ages.

See Example below

Actual Performance
Enter your sex, age, distance and time. Then click the Age-grade button to get your age-graded performance data.
Note: Times can be entered as hh:mm:ss or mm:ss.

Distance:
Time:
Your performance, as a percentage of the top standard for someone your age.%
If you were in the open age bracket, your time would be:
The top open standard for this distance is:
The top standard for someone this age is:
The factor applied from open to this age is:
Age-Graded Comparison
After you have calculated your age-graded performance, you can enter a different age here to get an equivalent age-graded performance.

This is especially helpful if you want to know how much faster you need to run against an older opponent or how much faster a younger opponent must run to "beat" your age-graded performance.

Target Time:

Age-graded performance level:
100% = Approximate World-Record Level
Over 90% = World Class
Over 80% = National Class
Over 70% = Regional Class
Over 60% = Local Class

Example:

Actual Performance
bulletSuppose a 51 year old male runs a 5K in 17:43. Enter this data into the appropriate boxes above.
bulletClick the Age-grade button
bulletThe age-graded performance ~82.62%.
bulletThis is 82.62% of the top standard for a 51 year old male runner.
bulletYou can use the +/- buttons in the Age box to change the age and calculate the age-graded data for the same time and distance.

Age-Graded Comparison: To determine how fast a 52 year old male would have to run the 5K to achieve the same age-graded percentage of ~82.62%.

bulletNext to the Age-Graded Comparison box, enter 52 as the Age
bulletClick the Find Time button to get the Target Time of 17:51.
bullet17:51 is the time a 52 year old male would have to run a 5K to get the equivalent age-graded percentage as a 51 year old running a 17:43.
bulletIn other words, if age-grading is the performance standard, then a 52 year old male running a 17:50 would "beat" a 51 year old male running 17:43.

Important: The Houston Area Road Runners Association (HARRA) uses age-graded performances to determine Runner of the Season results. This is good stuff!
