I used to like just going off for a day on the high fells in the lakes, or helping out with the local gamekeepers on the fell, what seems to happen is if i'm climbing a bank and can keep chatting as we're climbing I have no problems, but if they put their foot down and increase the pace or the bank steepens and I don't slow a little then, first of all I get more breathless than I used to, next the tears start to well up, and its time to back off and go at my relaxed pace, settle my self,
and its okay, I think I just don;t have the stamina reserves to push on, if that makes sense?
