It is pretty hard to do for a footrace based on performance, since that can change. Weight classes or something similar would probably work better, since you can't just pretend to be lighter than you are. Having a load of athletes that learn to run 1:50 on the dot would be kind of interesting in some ways though.
Otherwise I guess they could do something similar like horse racing divisions where they add weights and shit depending on horse, jockey size and previous performances, but those are more focused around making betting more lucurative, so I'm not sure how that would mesh with sport competitions.
