I managed my "tour", turned into a one-way ride in the end though as I took the train for the return leg. I felt that trying to ride home in one leg would be a bad idea, I thought this after I was past Bala on my ride 60+ miles in and my legs felt dead!
In the end I managed to do the ride in 7hrs 45 mins which I felt was a good time but I was absolutely knackered by the end of it.
I didn't do much riding when I got the other end, my legs felt bad the day after and I still felt pain in them the day I got back off my holiday (Wednesday). My bike also suffered a bit of salt damage to the chain and rear derailleur despite two cleaning and lubricating sessions.
