Age Grade Calculator

Age Grade Calculator

The age-grade percentage is a method used to identify the quality of a performance adjusted for gender, age, and distance. An age grading 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 the these factors to provide a percentage result. The higher the percentage result, the better the performance. Age gradings are calculated with reference to tables (maintained by Alan Jones here) compiled that consider a range of performances by different types of athletes.

How Age Grades are Calculated

Age gradings are calculated with reference to tables compiled by considering a range of performances by different types of athletes. This age-grading calculator uses the tables maintained by Alan Jones

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

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.
