Not trying to sound hypocritical, I have never run under 4 minutes before(heck, I have never run under 5 minutes before lol), but given that men have broken 4 hundreds of times, maybe it is just a mental barrier for women?? I understand that women have biological differences from men, and the WR for women is respectable, but maybe it will be broken soon, given the recent technological advances(or technological doping as some may call it), perhaps there is more of a chance now? Who would you nominate for the female Roger Bannister? Who will break 4 minutes for the women's mile?
For the women reading this: If any of this seemed offensive to you , I apologize. I have done so unintentionally.
