You are still going to have a biological advantage. Bone structure, muscle mass, endurance, reaction time, oxygen capacity

These are things that persist even after chopping your penis off or taking hormones - you can't undo the changes that your body went through during the developmental phase.

Someone male who was on female hormones literally their entire life since maybe age 0-2? Ok, you have a case. Otherwise it's just incredibly unfair for women to compete against.
