Any PTIs or sportsmen have any sure fire way of increasing ones running speed? Intervals or just plain old constant running? I can run for long distances quite easily but just cant up the pace at which I run. Even over shorter distances, 1.5 miles for example, I run at almost the same pace as for an 8 mile jaunt. Im pretty swift over 100-300 meters though so its not that Im incapable of sprinting. Does anyone else find that they just cant get faster? Oh, and Im not a pie eating lard arrse before anyone suggests it.
