Thats good advice. I'm guessing your fairly laissez faire on running routines ie)just do as much as poss whilst mixing it up and including rest. Is there a rough split I should be using? (ie 1 rest, 1 non run, 1 fast, 1 long and 2 other?).
Are weights ever useful (specifically lower body - leg press or maybe squats/deads?) especially if doing high volume of press?
