I know I’m in the process of building a series on Talent Development and specialization, but today is a frantically full work day, and there are some really interesting sports stories from around the world, so I thought I would deviate to a (not totally) unrelated topic and look at two of them in a quicker post.First, Chrissie Wellington was at it again yesterday, this time in Ironman South Africa. She won the race in Port Elizabeth in a new women’s record for Ironman events, an extra-ordinary 8:33.56. That broke her own Ironman record of 8:36.13, set last year in Arizona. That time was good enough for eight overall, and perhaps most remarkably, her marathon split of 2:52.54 was the fastest of the day, men or women (just a note, her fastest ever time is from Roth, an 8:19.13, but a number of people have suggested that this is a short course. Others say it’s not – I can’t verify who is right on this one! The men’s time there is also super quick, so whether it’s short or just fast, comparisons of Roth to other events seem a little tenuous…)
Challenging the men – gender differences in sport
It’s yet another jaw-dropping performance from a woman who only came to the sport late. Wellington is, if we stick to the theme of the last few posts, a classic “late specializer”, and in my opinion, a great example that talent goes a long way! Not that she was idle in her youth – she describes herself as sporty, but her focus on triathlon, following a sabbatical in Nepal, is as recent as 2007. Within years, she’s not merely winning, she’s rewriting the sport’s record books, and moving it into a new era. The message she gives is not “you can be anything you want to be”, but rather “It’s never too late to be great!”…if you have the ability, that is..!
And with her latest performance, the inevitable question is again whether Wellington is in the process of closing the gender gap, and how long will it take for a woman to win a men’s race outright?
This was something I looked at last year, when we named Wellington as our Sportswoman of the Year for 2010. Wellington is well on the way to ‘defending’ that title, but what I have described below is a similar discussion and analysis of her times relative to men’s performance, because I’ve been asked about it a few times this morning already, and it’s a pretty intriguing question in sports sciences.
Wellington in the open race – placing in the overall race
Wellington has rarely been outside the top 10 overall of her races – 7th in Roth, 7th in Korea, 8th in Arizona and now 8th in Port Elizabeth. Her marathon times in some of her wins a regularly bettered by only a few men in those races.
The problem is that these direct comparisons present some misleading possibilities. For example, if you took Paula Radcliffe’s marathon WR of 2:15.25, she would place 13th in yesterday’s Rotterdam Marathon, and 10th in London in 2010.
Yet, when you take that time and look at it against a larger group, you see that it ranks outside the top 400 PER YEAR (I recall that it was 473rd on the world lists for men last year), and outside the top 3000 in history! A once-off record can stack up well in a given race, but the same doesn’t apply against the collection of races.
That’s partly because a race like Ironman SA brings a good elite field, but it lacks depth – the best men are spread across dozens of races, and gather together only in Hawaii. The way the competitive racing circuit is set up, it facilitates a “spread” of ability, not a concentration.
Similarly, the London Marathon has an amazing elite field, but it’s only 6 or 7 deep, with the rest choosing Rotterdam, Paris and Boston to race in. So once you get below 8th or 9th, you move away from the cream of the men’s sport, yet you’re comparing them to the very best woman in history. And that’s why the best comparison will come from either overall comparisons or at the pinnacle event, Kona in Hawaii. And incidentally, there, Wellington finishes in the 20s – 22nd in 2009, for example, which is still exceptional.
By time – Wellington’s times relative to men
The other way to compare performances is to look at time. This also brings some problems, and it’s particularly difficult to benchmark female performances in a sport like triathlon. Three disciplines, differing conditions from one race to the next and within each race (thanks to the length), and race tactics make direct time comparisons less reliable than for track where records are often structured and paced.
You can do this for track and field, however. The graph below shows the comparison between the men’s world record and the women’s world record for the track events. You’ll note that all women’s records are between 9% and 13% slower than the men’s times. Given the long history and the relatively standardized conditions (for world records, which are almost always set in ideal conditions), these numbers show pretty clearly that men outperform women by around 10 to 11%. Radcliffe’s marathon record, ranked outside the top 3000 all-time, is 9.2% off the men’s WR.
Now, let’s look at Wellington’s performances in the Ironman, as shown by red symbols below. First, what is her place in history compared to other winners? Below is a graph that compares the winning performances at Kona for women to the men’s winning performances since 1995 (three generations of athlete). This is done so that the varied conditions (and Kona can be very different, with heat and wind) are somewhat controlled for.
The difference, you can see, is pretty much the same as for the track and field events, with a few exceptions, where women are well down on the men (upward of 13%). Wellington arrives in 2007, and goes from 10.8% to 9.7% to an amazing 6.7% slower than the men in her three wins. In 2010, Mirinda Carfrae was only 9.8% off the men’s winner.
Clearly, Wellington has been to the Men’s Kona winner what most female track and field world record holders are to their male counterparts. She is, from that point of view, in exactly the right place compared to the best men, and edging the event forward.
There are also other exceptional performances – the blue triangle above in 2002 is Natascha Badmann’s 9:07 performance, which was only 7.5% slower than the men’s winner that year (Timothy de Boom in a relatively slow 8:29:56). This Badmann performance also shows up the flaw in this analysis – year by year is too variable - was that men’s performance just very weak that year? Did race tactics affect it? More than likely…The fact that two years later, Badmann wins the race a full 15% slower than the men’s winner confirms this – year on year comparisons of winners leaves some variability, and that’s why a more “rigid” benchmark is needed.
All-time comparisons from Kona
So let’s use the men’s course record as the benchmark. There are problems with this comparison, too, of course. For one thing, variable weather from one year to the next can blow out the differences when you compare isolated performances with a ‘best ever’ performance, but I think the trend will be revealing when combined with what we discussed above. You could do this same exercise with the average of the men’s times, incidentally, and subtract about 3% off the difference.
So, in 1996, Luc van Lierde of Belgium won the race in 8:04:08, which still stands as the record today. Comparing all the women’s winning times since 1995 to that performance, Wellington’s impact on the sport stands out a little more, as you can see in the graph below.
This graph suggests to me that Wellington has moved the sport into a new era for women – where the gap was previously 12%, she’s moved it down to 10%. That may seem a small improvement, but bear in mind that if the world record in the marathon were improved by 1%, it would be 1 minute 14 seconds faster. So Wellington really has pushed the event forward.
Her Roth performance is 6.1% slower than the men’s record, and yesterday in South Africa, she was only 5.8% behind the winner. Those are remarkable performances, but again, the nature of single races does sometimes allow the very best (Wellington) closer to a ‘diluted’ men’s field than would be the case against the very best men.
What does seem true, however, is that Wellington is getting better. Therefore, she may well be primed to break the Ironman record in Kona this year – certainly having moved the overall Ironman record faster by many minutes, her 8:54.02 seems ready for revision. If that happens, she may well bring the women’s record down to within 9%, maybe even 8% of the men’s time, and that would confirm what an extra-ordinary athlete she is.
Quite apart from all this is her media-friendly personality, her desire to engage and support the growth of the sport – she’s a champion that the sport needs, and perhaps every sport wishes it could have. Let’s see what she produces next!
Marathon stats from around the world
This past weekend also saw the start of the Spring marathon season, with some quick racing in Rotterdam and Paris. Next week are the big two races of the spring, London and Boston, and we’ll be covering those with our usual analysis.
But until then, some interesting analysis came out yesterday, courtesy Ken Nakamura. He looked at the winning times from all the major marathons and determined that Rotterdam is now the fastest marathon in the world, with Berlin and London in second and third.
Perhaps even more interesting, the sub-2:06 barrier is now the standard for elite marathon running - 24 men have cracked this barrier, the latest being Wilson Chebet in Rotterdam (2:05.27). Compare this to 2:07, which has been broken by 75 men, and you see that the gap between good and great now lies around 2:06!
2:08, which used to be a world-class performance, is now comparably mediocre, such has been the explosion in performance in the last decade. The rest of the world need to pay attention, because when the standard shifts, so too much expectation, or you’re in danger of being left behind. This is partly the case in SA, where we haven’t improved nearly to the same degree, yet celebrate 2:10 marathons as world class. 2:06 gets you to the banquet, not 2:08…
The series on training, talent and champions resumes later this week (I hope!).
