Older Age Groups 1500m

The duncanSCORE is a new method of evaluating Masters’ performances. And it is different than age-grading. Different how? Better then age-grading?

Age grading compares how you did against an estimate of the maximum possible performance in the event for your age-group. That’s right. Not against the World Record. It’s a bit more complicated. It’s compared to a performance beyond the WR. One never accomplished when the factors were created.  These theoretical maximums are produced/updated about every 8-10 years (2 Olympiads).

The duncanSCORE is simpler


The duncanSCORE is a heck of a lot simpler. It takes performances (principally from mastersrankings.com) and creates a bell curve. As you probably remember from your high school or university stats courses, 68% of results are within 2 standard deviations of the average (the mean). One standard deviation above. One below. A little over 95% of performances are bounded by 4 standard deviations (2 above, 2 below).

Using this methodology, the duncanSCORE gives you a key statistic. You get a percentile of where you stand i.e. the percentage of athletes that your performance equals or exceeds. The “what” you are compared against is consistent. Your age-group. Your event. Not a single, theoretical performance that falls on a curve.

We need performances

But to do this well, the duncanSCORE needs performances. The more the better.

However, as the age-groups get older, after about age 55 or 60, the number of participants begins to decline fairly rapidly. This is especially the case for Women.  And the longer, more technical events

To improve this situation, more results have been sought out and added. From mastersrankings.com we have added the years 2017, 2018, and the performances posted for 2019 at time of processing. Additional results from British Masters rankings 2008-2012 and Martin Gasselsberger’s world rankings 2008-2012 have also been utilized.

All these additions for age-groups 75+ have been completed now for the 1500m.

My desire in all the new input for the duncanSCORE has been to improve the depth of the data, yet minimize the impact of any changes. Mission accomplished for the 1500!

But like the other events there still aren’t enough performances for M95, and W90 and W95.

Perfection is elusive.

If you are 75 or older and race the 1500m, check out how you rate against your peers from around the world. And if you’ve just turned 75 or moved into an older age-group, put in last year’s time and see how it would fare in your new age-group.  It’s very easy, click here

Track DE

Then from the drop down menu choose your age-group. Next select  “1500m” from the track EVENT drop down list. Finally, enter your time (in minutes and seconds) and then click the green  “Ok … Done …GO” button.

You will be given a “score” and a “percentile”. The percentile tells you what percentage of your age-group peers across the globe you are (as fast as or) faster than. Very easy!
