gender-neutral Olympics?!

As usual, reading the latest issue of Significance is quite pleasant and rewarding (although as usual I have to compete with my wife to get hold of the magazine!). This current issue is dedicated to the (London) Olympics. With articles on predictions of future records, on whether or not the 1988 records can be beaten (the Seoul Olympics were the last games before more severe anti-drug tests were introduced), on advices to Usain Bolt for running faster (!) and on the objective dangers of dying from running a marathon (answer: it is much more “dangerous” to train!).

However, a most puzzling (and least statistical) article is Stephanie Kovalchik’s proposal for a gender-neutral Olympics.  The author’s theme is that, in most sports (the exceptions being shooting, yachting, and horse riding, where competitions are mixed), raw performances of women are below those of men for physical and physiological reasons. Stephanie Kovalchik thus “question[s] whether a sex-stratified Olympics is the product of groundless stereotypes about male athletic superiority or could be justified by gender differences at the elite level of sport” (p.20). Unsurprisingly, she concludes that no amount of training seems capable to bring both sexes at the same level: indeed, for instance, Paula Radcliffe, the fastest female marathon runner (2:15:24), is still 11 minutes beyond Patrick Makau, the fastest male marathon runner (2:03:38). They are both super-terrific athletes, the top ones in their categories. Now, Paula runs half-marathon and marathon faster than the best male runners in my team (Insee Paris Club). Where’s the problem?! And why should we try to rank Paula against Patrick?!

A parenthesis: the author mentions a most bizarre (but eventually inappropriate) exception: in the Badwater Ultramarathon, a crazy race covering 135 miles and going from Badwater, Death Valley, at 280’ (85m) below sea level, to the Mt. Whitney Portals at nearly 8,300’ (2530m), with a total of 13,000’ (3962m) of cumulative vertical ascent, four women won over the 25 occurrences of the race. I found this phenomenon quite curious and went to check first the records of the comparable ultra-trail du Mont Blanc, another even crazier race (168km, 9,600 metres of positive height gain, at mostly higher altitudes, between 1000m and 2500m), and saw that last year the first woman in the race was 13th in total, with a difference of four and a half hours with the winner (20:36 hours, believe it or not..!). Going back to the Badwater Ultramarathon, checking the results showed that the race actually attracts a very limited number of runners, from 17 finishers the first year to 83 last year (where the first woman was 7th, about 5 hours from the winner), with a huge variation between runners and between years. So I would not draw so much of a conclusion from this example, certainly not that “in an event where sheer dogged endurance, guts and determination must count for almost everything, we may be there already”. It is rather a law of small numbers: such extreme events attract a very small number of participants with incredibly variable finishing times, e.g. two of the four winning women won out of…5 (1988) and 2 (1989) finishers, while the two other victories were achieved by Pamela Reed over 45 (2003) and 57 (2002) competitors, a much more remarkable feat. Meaning that one or two runners missing or giving up brings a huge change in the final time. The ultra-trail du Mont Blanc now involves a thousand runners and there, numbers count. End of the parenthesis (with total respect to all those runners, I wish I could do it!).

Going back to the paper proposal, Stephanie Kovalchik considers that “credit merit apart from hereditary luck will favour individuals who possess the best genes for sport. Thus, prejudice – in the true sense of pre-judging – at the Olympics runs deeper than gender lines. Geneticism more than sexism is to blame for making the possession of a Y chromosome an advantage at the Games” (p.21). She suggests to instead rank athletes by a “statistical adjustment [that would]  remove the confounding factor of genetic inheritance, to provide a standard of achievement that all could aim at, no matter what their hereditary luck” (p.22). In essence, the winner would be the one that had gained the most compared with a “demographically matched sample of untrained individuals” (p.24). If I may, this sounds perfectly ridiculous! First, the whole point of the Games and of any sporting competition is to determine the “best” athlete. This is not an egalitarian goal and can and does lead to poor outcomes such as cheating, drug enhanced performances, nationalistic recuperations, commercialisation, bribery, and so on. It is thus perfectly coherent to be against those competitions. (I am not a big fan of the Olympics myself for this reason. However, without competition, even at my very humble level, and with little hope of winning anything, I would certainly train much less than I currently do.) But to try to reward efforts to counteract physical differences sounds like political correctness pushed to the extreme!  Second, and this is why I find the paper so a-statistical!, the adjustment must be with respect to a reference population. If we carry the argument to its limit, the only relevant population is made of the athlete him/herself. Indeed, genetic, sociological, cultural, geographical, financial, you-name-it, elements should all be taken into account! Which obviously makes the computation just impossible because then everyone is competing against him/herself.

New York City 1/2 marathon

Posted in Running, Travel with tags , , , on August 16, 2009 by xi'an

When I went running to Central Park this morning, I knew something was on when I saw police stationed at every entry of the park. Almost immediately, I hit an endless flow of runners and one of them told me he was taking part in the New York City 1/2 marathon. This was most frustrating as I would have registered, had I known… This is the fifth time this type of “coincidence” happens to me, after Roma, Venezia, Fairbanks, and Ottawa!!! I then decided to run against the flow to see as many runners as possible, as well as the race track. The track did one and a half loops in the park before heading south in the city along 7th Avenue, I think, all the way down to Battery Park. After two miles or so I came across the head of the race and there was…Paula Radcliffe herself!, less than a meter away from me (for a few seconds!), on her way to victory in 1:09:45!!! I vaguely contemplated running next to her to better appreciate this incredible pace but this could have been against regulation and anyway I don’t know how long I could have stood this 18k per hour pace in such a humid heat! So I kept on the loop within the park, meeting higher and higher numbers up the 1400’s, till I crossed “runners” walking their second mile with very little chances of completing the whole race.
