Women's sport has never been less intense. I trained six hours a day, six days a week with boys 40 years ago. We have categories across sport for all sorts of reasons so that we can give opportunities to everybody. There is a massive difference at a Olympic level of anywhere between 10% and 30%. It's absolutely colossal. If you think of someone like Michael Phelps and how dominant he was, he still only beat his rivals by less than 1%.
