Age Grade Calculator

Age Grade Calculator

This age grade calculator uses the latest age-grading factors and standards from 2015.

Age Grade Calculator

Select your gender, event and time result, then press the Calculate button to retrieve your age-graded performance details.


Times can be entered as hh:mm:ss or mm:ss or mm – if no colon is supplied, the time will be taken as minutes. 

  • Age Graded Percentage:
    Your performance, as a percentage of the Open Standard for someone your age:

    • 100% = Approximate World-Record Level
    • Over 90% = World Class
    • Over 80% = National Class
    • Over 70% = Regional Class
    • Over 60% = Local Class
    • Under 60%
  • Your Age Graded Time:
    Your time as judged against the open standard for someone this age.
  • Age Standard:
    The top standard for someone this age.
  • Open Standard:
    The open standard for this distance.
  • Factor:
    This factor is used to calculate an age-graded result (as defined by your gender and event) so that meaningful comparison can be made between athletes of different ages.

Age Grade 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.

    Curious as to why the standards are so tough? If I run a 19:59 5k at age 30, I’m just in the local class w/ 65%. Does this mean amongst all competing runners or just the general population? Thanks!

  2. Seems to be a bug in the code – the 5km/10k selection is ignored and all done on 10km basis. My 25min times for 5km gave a >153% score. :-).

      Hi Steve, thank you for your feedback; it’s always appreciated.
      Re the age grade calculator, can I ask which age you put in? Also, which browser were you using? Cheers.

      • I put in age 56. And time of 24mins not 25 (typo). I found changing the gender and distance selections made no difference to the given answer of 153.75%.
        I’m using Windows Internet Explorer v11 as browser

          Thanks, Steve. Yes I see what you mean now. It’s a problem with my code for Internet Explorer, it works fine for other browsers which is why I couldn’t see the problem straight away as I use Chrome. I’ll try and get it fixed over the coming weekend.
          Thanks for letting me know and hope the training is going well.
