What you get out of it will depend mainly on what type of runner you are. As 400/800 guys come from all different types.
Say it was a 200lb Muscular guy mainly sprint speed (11.5) not much training on endurence[/quote]
Then I would tell you he shouldn’t be a 400/800 guy. He probably shouldn’t even be a 400 guy and just stick with the 100/200.
Unless the guy wants to drop 40lbs then he shouldn’t even consider running the 800.[/quote]
Do You Think Dropping 40lbs wouldmake him anyslowerof a sprinter??? Or would less of a load improve his speed???
