Thanks mudlugger and Emmilou.

Further info, furthest I've run is about 12 miles, so this will be a considerable step up, but at the end of that sort of distance I feel fine to carry on. I'd certainly be comfortable walking the distance and height gain of the full tour, but appreciate that running the distance is a different matter, my thought is that I'd be struggling in the latter half of the race but would be able to complete albeit in a slow time.

Re fitness not sure how to say more other than the time I do for the 5.5mile (it's over moorland, similar terrain to Pendle but less steep), I guess I wouldn't be throwing up at the end of it and could comfortably carry on, but by fell running standards I'm well at the bottom of the table.

Experience is just a about a year of fell running but not any races, say about 3 times a week. Plenty of experience hill walking and happy to navigate in anything other than a full whiteout.

Given the route I guess there's plenty of places where I can head back from if things are going badly.
