I know it's been mentioned before but the 261 woman was protesting about not being able to compete with men by holding a race where women can't compete with men. A bit like striking a blow against racism by having "black only" water fountains.
I saw that 261 marathon recently and the field was full of male pace makers. What a cop out. The winner ran a respectable 2.50 but 2nd place came in half an hour later. I think the poor little thing could have managed without a man on her arm.
