Hi Maureen
I'm sure you'll have no trouble with the walking on the Ahr Valley holiday. This is a Grade 1 walking holiday (the easiest kind) - which means you'll get plenty of rest breaks, you'll mostly be on good paths, and the climb will be no more than 300m a day. As you enjoy walking, I'm sure you'll be fit enough to get the most from it.
Also, I doubt that anyone will be charging off into the distance, as this holiday is more about taking your time and enjoying the wonderful scenery.
Kind regards,
Olly, your editor
