Ah, sorry, I didn't know it was that important. I'm fairly heavy for my size I guess. 1.79 meter or 5'11 and 73 kg or 160 lbs. Can't really reduce my weight though, since I'm already around 8% body fat..

Edit: I figured the drop decrease would make a difference, but in which way? Primarily joint impact / muscle fatigure or does the running technique need to be altered too?
