I think the feet/ankles/left knee will be fine on Day 1 and the painkillers will get me through Day 2. But Day 3 is terra incognita (fortunately I should be able to get into TfL territory fairly quickly and from then on I can hop on a bus if necessary !). The whole walk - south coast to east of Hull - is split into four parts and I haven't committed to the others until I've tested things out on this one. This is also the one with most of the climb in it. So if I can get through this then the others should be a fairly safe bet.
OK, to quote Zebedee, "Time for bed".
