Clearly the two could be connected although I don't think it's as simple as that. I'm 6' 0" and 16 st 6lbs give or take a pound or two. Sometimes when I'm dehydrated I can be down to 16 St 2lbs but it's really neither here nor there. (Yes I know that gives me the same BMI as a walrus but I am fairly heavily built in the upper body) I was this weight before I started my routine over twelve months ago and I still am. Even having ramped things up considerably over the past three months there's no difference. If I eat any less than I do now I find I just go flat when I'm out running etc. I eat fairly well, fresh meat (game), fish, veg, wholemeal bread, eggs, some rice. (I've always eaten like this) I am of course a hell of a lot fitter. I ran five miles in under 50 mins a few weeks back, something I couldn't have dreamt of a while back. Problem is, that's ten minute miles. On a three mile run average much the same, maybe 9:40 or something. If I try to run faster I seem to just get knackered quicker and still take the same time overall. I'm not a total, knacker, I've just finished an hour circuit training and although elements are a push it's not beyond me. I can walk ten miles without noticing, row for an hour or more with no mither but I just cannot run any faster. Even if there is no prospect of me getting back in I'd at least like to get to the fitness standard and run time and BMI are the only things I can see I'd fail on. (Might give the MO a coronary at the medical though! ) Any thoughts?
