Race Walkers, This One’s For You

Race Walkers, you’ve been waiting! You have all been very patient with me. You now have an age-grading alternative.

Now you can get a duncanSCORE on RW5000m (track). Let me review how it is put together.

How it is done

From mastersrankings.com, we have taken the the best annual results for each walker recorded from 2013-2016 inclusive. In total, this database contains over 12,500 performances for all age groups.

The results for each age group have been turned into a bell curve, with an average, and a standard deviation calculated. With this data we can calculate a score (from 1-999) and a “percentile”. The percentile rates you against all others in your age group. For example a 70 percentile means you are as fast or faster than 70% of all other 5000m Race Walkers in your age group in the world.

For the first time you can compare yourself to all others in your age-group … not to some mythical Walker created in the age-grading system.

See a more thorough explanation here.

You can get your own evaluation by first entering your age-group from the drop down list. Next input the event from the drop down (RW5000M) and then add your race performance time in minutes and seconds, including tenths. Then click on the green button and you will see your results.

Here is the link:

Track DE

Data is available for all age-groups up to and including M85 for men, and W80 for women. Past those age-groups there aren’t enough performances available.

I am hopeful that I can do to RW what I have been doing for older age-groups, finding and adding performances from before 2013, and adding 2017 and 2018. Hopefully that let’s us add the older ages. This might give us results, too, for RW1500m, and RW3000m.

Something to add to my list.

For The Milers

You middle distance runners have been quite patient. I know many of you non-metric types are, really at heart, Milers, and the duncanSCORE has not provided calculations for your favourite event.

Your wait is over!

You can now see how your times relate to all others in your age-group in the outdoor Mile.

Your Miles raced may not have been at Iffey Road or Oslo’s Bislett Stadium, but I’m certain they have been highly memorable. The Mile seems to have that special magic that imprints the experience in your brain. So relive that experience by seeing just how well it relates to all other Milers in your age-group.

And while you’re at it, compare your Mile calculations with your 1500M score and percentile. How close are they?

Also added are calculations for the Outdoor 3000m. So be sure and check your performances in that event, too.

Just click here, choose your age-group, select the event, then add your time  …

Enjoy!

A Better Read on Older Age Groups (2) – 400m

This is the 2nd post on my work to improve the quality and depth of duncanSCORE readings for the older age-groups (75 plus) and another installment on duncanSCORE 2.0. I have now updated the data for the 400m. The previous post highlighted the work done for the 100m and 200m.

Let’s Review

Here is a quick review. To date all duncanSCORE calculations are based on an accumulation of mastersrankings.com best individual performances for the years 2013-2016 inclusive. In case you are interested or would like a refresher, here are the nuts and bolts of how the calculator works and the results generated.

For most age-groups and events there are many hundreds and often, thousands, of performances. But as the age-groups get older, after about age 55, the number of participants begins to decline rapidly. This is especially the case for Women, and the longer, more technical events.

To add performances to these older age-groups I am including from mastersrankings.com the years 2017, 2018, and for 2019 the performances posted at processing time. Further, to boost the number of performances, I have included the US rankings John Seto had produced for the years 2008-2012. Before John did the World rankings, they were maintained by Martin Gasselsberger and I have used Martin’s data from 2008-2012. The British Masters also keep rankings and I have used those available from 2008-2012.

What this means

What this means is that I have been able to more than double the number of performances accessed by the calculator, which improves the quality of the output. For the 400m this really impacts M85 and M90 and W80 and W85, making the duncanSCOREs for these age-groups much more solid. For M75 and M80, and W75, the added performances don’t materially change the results.

Sadly, however, there still are not enough performances to have reliable scores for M95 and W90 and W95 age-groups.

Take a test drive

If you are 75 or older and race the 400m, take a quick peek at 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  “400m” from the track EVENT drop down list. Finally, enter your time (in minutes and seconds, or just in seconds), 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 faster than.

Have fun!

More Results-A Better Read on Older Age Groups

Let’s get down to it!

The previous post introduced some of what’s coming in the next few months (duncanScore 2.0), and here is some more detail on the first improvement now released.

Rates of Participation Decline With Age and Distance

As a general rule, the number of performances in any particular age group gets fewer as the groups get older beyond M-W 50.  Also, Women tend to participate less than Men. The participation further declines fairly dramatically the longer the event. Think 10000m vs 100m) and with increases in difficulty/danger (hurdles/steeplechase vs the “flat” events).

But here’s the thing. There is an inherent weakness. Where there aren’t a lot of performances, the projected resulting output can be misleading. As you can imagine, it will be many more years before there will be enough performances for an accurate read of Women’s 95 Pole Vault in duncanScore. It’s not an issue for the vast majority of the results produced by duncanScore, but when we go beyond M85 and W80, sometimes the output can be a little “shakey”.

As I wrote in the previous post, in order to boost the “robustness” of these older age-groups I have added legitimate outdoor performances to bolster the duncanScore wherever I could find them. Currently all results are based upon 2013-2016 input from mastersrankings.com. But now for age-groups M75 and W75 and older I have added performances from:

  1. mastersrankings.com World rankings from 2017, 2018, and available 2019 rankings
  2. mastersrankings.com U.S. rankings from 2008-2012
  3. British rankings from Power of 10 2008-2012
  4. Martin Gasselsberger’s (the keeper of World rankings before John Seto) World rankings from 2008-2012.

More Than Double the Performances

By adding these other years and data sources,  we have more than doubled the number of performances for these older age-groups, enhancing the quality of the Scores and percentiles.What’s also interesting (and good!), looking at results so far, this has usually meant only small changes. Most performances register a difference of perhaps 1 or at most 2 points in the percentile from before.

This is the first part of duncanScore 2.0 … a plan to enhance quality, usability and add useful features for you the Athletics competitor. Ultimately all events for these older age-groups will have the results from these additional data sources.

I have now completed Men’s and Women’s 100m and 200m and they are “live”.

By all means, if you are a Sprinter and 75 or older, have a look and see how your times stack up in version 2.0 with everyone else in the world in the 100m and 200m.
