You don't have any idea what it takes to run a 10.4 or sub 11 100 either. David Rudisha runs a 45.5 400. If you knew anything about sprinting, you would know the 400 is a sprint. to run a 45 400 , a person would have to least be able to run 21.0 flat. TO run a 21 flat their 100 would have to be at the worst 10.7. There is no way someone can run 11 and not break 22.
Take a seat.
