A couple of weeks ago I completed this route solo and unsupported. It's a mountain route (taking in all the trig points) from Llangollen to Barmouth, about 60 miles and 14,000ft.

For anyone interested in a read, my write up has just gone onto the High Sports (Shrewsbury) website, and if you are interested in doing it I'm happy to advise as best I can on logistics etc. It's a good but tough walk! The link is bottom left on the page under 'blog posts' - you get there eventually!
Matt.
