MillyTant is right - Ellis Cashmore has always been a rent-a-gob. He's been coming out with self-promoting crap for the last 40 years.
And isn't it dispiriting that Jasmin Paris's magnificent achievement in winning the 268-mile ultramarathon is now being used as a stick to beat us with? Paris did brilliantly. But her achievement is so notable precisely because it's an exception. Relatively speaking, female athletes do well at endurance events. But they don't do as well at events that require muscle power or bursts of intense speed. Name any track or field event you care to imagine (100m, 200m, 800m, javelin, shotput, discus, high jump, long jump, pole vault) and men are way ahead of women.
The notion that because one woman has excelled at an endurance event, men should now be allowed to compete alongside women in other sports is pure idiocy. Cashmore is an embarrassment to his university.
