Well done for completing and well done for lessons learnt!! Don't worry about the taxi bit - I'm sure we've all done that. When I walked Offas Dyke earlier in the year, on the day that it bucketed it down - having done 20 miles the day before and 15 miles on that day - I decided to get a taxi for the last 3 miles into Llangollen. Not sure that I missed much - and from my recollection - not sure that the 3 miles odd miles you missed after Burneside were anything that special. I also remember a lot of stiles/gates on the Dales Way - and really narrow ones that meant I was continually taking my pack on and off (I was camping and my tent was lengthways and wouldn't go through the little gates).
