Although running fast is important for the athlete, legalizit is taking the approach of a coach. I?m sure that the best coaches in the nation were not the best runners. In the fifties (before ?54) running seven days a week or twice a day was unheard of, humans were not physically capable of running sub-4 mile and women would never run a marathon. This is how new things come about, and our sport advances. I think that this is too advanced thought for just about everyone that visits this board, including myself.
Preach on
good luck
