Personally, I take the view if it takes your fancy then do do it!
Its too easy to sit back and say, can I, dare I and so on! I dreamed of hiking the Pennine Way for years, in fact this was my first REAL hike. I suffered I know, especially my feet, but in hindsight it was certainly worth it.
It was like me again when I dithered for a long time about hiking the GR10 in France and worrying about is it too far, is it too hard and so on. I did it in the end and feel rather stupid now that after being diagnosed with Prostate Cancer is was that which made me say to myself "S0d it, I'm going to have a go, no matter what advice, medical, health and safety, your too old and the rest of the nonsense I was bombarded with!"
