And, tomorrow, Caster Semenya can expect a hero's welcome, when she arrives home with her gold in the 800 meter race.
"If you take away the obvious ones it's actually really competitive", she added.
This, thanks to Olympic gold medals by Wayde van Niekerk and Caster Semenya as well as silver medals for Luvo Manyonga and Sunette Viljoen.
Briton Lynsey Sharp who was placed sixth in that race argued that the decision to overturn rules on testosterone suppression made competing against the women's Olympic 800m champion, Semenya, and other hyperandrogenic athletes hard.
Women are a heterogeneous bunch. Not so in the sport of athletics, where the IAAF (our worldwide governing body) is keen to limit the heterogeneity of women competing at the elite level. "I've competed against Caster since 2008 so it's nothing new for me".
And they're right, something must be done. This leads down to, or may lead to the awkward topic of - since Semenya has been called by some as "intersex" - transgenders... in which case, would the Olympic committee then resort to instituting a third category (gender) for competition sometime down the road.
What does "not woman enough" even mean?"So, that's all I can say".
However, this ruling was reversed a year ago when Indian sprinter Dutee Chand successfully appealed to the Court of Arbitration for Sport, which suspended the practice of testosterone regulation and challenged the IAAF to present better evidence by July 2017.
These regulations required female athletes to keep their naturally occurring testosterone below the so-called male range. But against all odds, Chand won.
There she finished behind Russia's Mariya Savinova, who has since been named in a doping report, with the World Anti-Doping Agency saying she should receive a lifetime ban. We've always heard that Phelps arms are really long, making him the ideal swimmer, and we know Bolt's extraordinarily long stride, making him the flawless sprinter.
South Africa's Elroy Gelant was well placed for much of the race, but faded in the last two laps to finish 11th.
August, 2009: Semenya wins the 800-meter world title in Berlin as an 18-year-old newcomer, dominating a field packed full of the world's best runners to triumph by a huge margin and stunning everyone watching.
So many believed she should not have been allowed to compete on this night at the Rio Olympics.
"We're not here to talk about some speculations", Semenya said.
"I don't know", Semenya said.
"She is a woman and she must be allowed to run like us", Sello said of Semenya.
"It is not a situation they can come out of winning".
Semenya is as deserving an Olympic champion as we'll ever see.
In a statement, she said: "I have a tremendous amount of respect for Caster". Testosterone is a strength-building hormone in both men and, usually in far lower levels, in women. Others refused to talk about the testosterone issue. She is now undertaking her PhD in Sociology at the University of Wisconsin-Madison.
