I stopped smoking 12 years ago & developed COPD 10 years ago (seems unfair but hey ho it's my own fault).
I went to Scafell last weekend to walk up with a pal from Wasdale Head but only got to 390m elevation before I ran out of uphill steam & turned back whilst my buddy went on with the crowds (it was very busy)
I'm hoping someone has experience they can share on how to improve stamina with this issue because I would love to get to the top again (I went up about 9 years ago after I was first diagnosed), but I have to say I am very aware if it's no longer possible (I'm 65) I won't try in a foolhardy manner that will either endanger friends or put the Mountain rescue members in a "need to rescue" situation
Thanks guys, Bill
