Well am glad to report I tried again last Saturday and returned home on Tuesday, all by myself

Saturday went from Runcorn to Prestatyn - This time I ignored the 5 route from Bagilt over the hills and stuck to the coast road. I made it 3 hours quicker and could still walk!
Sunday went from Prestatyn to Conwy (well just past) - This was mostly on the flat around the coast but did hit a massive hill at Ross-on-Sea (think it was called), I went via Landudno as I wanted to visit.
Monday went from Conwy (well just past!) back to Prestatyn - Followed the 5 from Conwy to the coast and it was good, a bit hilly but I knew that beforehand as I had the right maps (borrowed from the library).
Tuesday went from Prestatyn back to Runcorn - Very hot day and my backside was killing me, think because of the sweat. But my legs felt great which was brilliant as gave me confidence for a longer tour.
Thanks very much for tips etc... from my other thread.
Felt a bit emotional arriving back into Runcorn, couldn't believe I actually made it.
Would you believe I even left my bike lock at home by accident and was soon just leaving my bike with trailer attached while I nipped in places. Thought if a thief jumped on the bike, he/she would be in for a shock if they tried to pedal away with the amount of weight and would probably just tip over.
Cooked a bit of food myself but would like to have cooked more, gonna look into one pot cooking over the winter.
Walked quite a bit pushing my bike, as soon as I felt tired I just got off and pushed, was in no hurry to get anywhere. Out of everyone that passed had one person stop and ask if I was alright and did I need anything (because I was pushing). Ignored by almost all cyclists who where racing along on day rides, spoke to loads who weren't. The trailer is defo a good conversation starter, the amount of people who stopped to ask how far I was going etc... etc...
Downside to the one wheel trailer is finding somewhere to park your bike while doing stuff, a two wheel trailer would be better I think.
Best sign I saw was the image attached.
