I'm not sure when Coe made these comments - might have been yesterday - but he deserves A LOT of praise for standing firm on this. Some of these quotes are amazing.
“We have two categories in our sport: one is age and one is gender. Age because we think it’s better that Olympic champions don’t run against 14-year-olds in community sports. And gender because if you don’t have a gender separation, no woman would ever win another sporting event.
“We’ve always been guided by the science, and the science is pretty clear: we know that testosterone is the key determinant in performance. I’m really over having any more of these discussions with second-rate sociologists who sit there trying to tell me or the science community that there may be some issue. There isn’t. Testosterone is the key determinant in performance.”
