Hubbard is rumoured only to be in with a realistic chance of bronze in her Olympic event.
Which is bad enough. But like many, I am looking forward to this being brought to the forefront as its been going on too often already at non-Olympic level.
Its so hard to beat men. Sometimes in running races I've ran really hard and done well and won the womens' event or placed (not at any great level but locally) and sometimes a particular man will "adopt" you as the person to beat in the race or try to sprint past you at the finish. So effectively you are racing them rather than a faster woman 2 minutes up the road that you can't see.
And I can finish fast, yet I have pushed my heart to almost bursting point and felt that I didn't care whether I died in the process, and I will still often be beaten by a man who is finishing 25th or 30th in the mens' race while I am in the top 3. They are just bigger, more powerful, more ayrodynamic, have narrower pelvis, bigger hearts, more blood volume, a higher VO2 max, longer stride length, bigger muscles, bigger lungs and so on.
But still you will read some mens' comments about how women "just need to get faster/try harder/train harder". Michael Phelps has longer arms and hence his advantage is fair yes, but Michael Phelps' arms aren't SIX TIMES longer than his nearest rival's, which is the permitted amount of testosterone for competitors in Olympic running events! Yes, 6 times the amount of testosterone that has ever occurred naturally in any woman tested at the Olympics who hasn't failed a drugs test, and still the top 3 in that last Olympic womens 800m can't comply with the ruling and won't be allowed to compete.
