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:

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.

How Much Class Do You Have?

Today I want to write about “Class”. No not that kind. I’m talking “World Class” and “National Class”.

What in the world do we mean by World Class and National Class? I bring this up because in Age Grading terms, 90%+ is “World” Class, and 80%+ is “National” Class. 70%+ is “Regional” Class. I can’t find any reference on the WMA web site but the USATF Masters site does offer some discussion, and posits these AG percentages and their relative “Class”

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

Beyond 100%, there really isn’t any clarification or definition of the levels. Is Slovenian (pop just over 2 million) “National” Class the same as U.S. (pop 325.7 million) “National” Class? I wouldn’t think so. And who decides on “regions”? Is that a state? Or a province? Or in Ontario’s case the GTA (Greater Toronto Area)? Why is there no definition? And why 80% for “National” class? Why not 85%? Or 75%? Surely it can’t be that hard! I’m guessing it has been purposely left vague. Which frustrates me to you know where.

With the duncanSCORE I set out to do things differently. And as much as possible, one thing I hope to do differently is to define things. Like percentages. What do they mean? You probably understand the percentile calculated by the duncanSCORE i.e. your performance is as good or better than “xx%” of Masters athletes in your age group/event. Fairly straight forward.

Now I would like to define the dSCORE percentile further. Typically, what kind of percentile do you need to win a medal at a WMA Outdoor Championship? To make it to the final? To qualify for a semi-final after the opening round?

I’ll be exploring those questions over the next few weeks, so stay tuned.
