Age Grade Calculator

The age grade calculator is a method used to identify the quality of a performance adjusted for gender, age, and distance.

It is a great way of comparing your own performances across various distances and also against the performances of other runners as it allows for adjustment to these factors to provide a percentage result. The higher the percentage result, the better the performance.

Your Age Graded Result:

  • 100% = Approximate World-Record Level
  • Over 90% = World Class
  • Over 80% = National Class
  • Over 70% = Regional Class
  • Over 60% = Local Class
  • Under 60%

How Age Grades are Calculated

Age gradings are calculated with reference to tables based on the standards/factors that are as approved by the World Masters Athletics (WMA). Your performance is evaluated against the approved standards to determine your age grade performance. Here’s a breakdown of what each factor is and how it impacts your score:

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.
Open Standard:
The open standard for this distance for your gender.
Age Standard:
The top standard for your age and this distance.
Your Age Graded Time:
Your time adjusted for age against the open standard.

Age Grade Comparison Form

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.

    I’m also getting an incorrect result – at 29yo and 27:17 for the 5km distance…. Giving me world class status even though I’m far from it 😉

      Hi, thank you for letting me know about this. Seems in this scenario the calculation is getting into a bit of a muddle. I will look at this right away and correct it :-). Thanks again.

    I put in 30:55 for a 5k as a 29 year old and it gave me 101.393% which doesn’t seem right

    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!

  4. 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

        • Matt says:

          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.
