I'm not saying it's not possible to be motors
But something I've noticed across several sports is amateurs really can't grasp how elite some human beings can be biologically due to accidents in evolution
So any significantly elite performance is indistinguishable from tech/drug doping
It's all in the mitochondria and someday they might be able to test at birth (or even before)
And now they are developing mitochondria transplants so just imagine TdF or the Olympics in a few decades
