possibly the most impressive thing I've ever done in my life. not sure what that says about life in general, but I've walked 190 miles across England in 12 days, carrying tent and camping most nights, and climbing lots of big hills. broken boots, sore feet, fog, wind, rain, but lots of amazing weather and scenery and a few nice people on the way (fortunately no crowds!)
but the question is now begged; what next?
