A few months back I decided to start walking around the Surrey countryside, so armed with a map, bottle of water and GPS (of course) off I went.  I took the GPS because I was sure there was a way to share my route with others, plus I wanted to save them for posterity. I've since found ShareMyRoutes.com which lets you upload GPS tracks so other can enjoy your walk/cycle/paddle. Four of my routes are already there. Enjoy
