I think that every race should have a clinic in a trailer where the "athletes" can get whatever fixes they want for free. It would make the poorer, less sophisticated ones more competitive, making the sport more exciting, especially if there is an occasional fatality. The richer riders could still practice in privacy to avoid any stigma and keep their endorsements, and maybe it would spawn a really big competition to create the best cocktails, benefiting high school and college footballers.
