Interesting points. I understand what you are saying about the challenge and the contenders effort. All very valid. I also understand the idea of using gps tracks not being in the spirit. I guess it's a sense of personal ethics. I know on my summer round (where I was heavily supported and just followed my excellent navigators) I felt that I somehow hadn't quite done it properly since it just became me and my physical/mental ability versus the round rather than it being a test of my mountaincraft/fellrunning ability (navigation, route choice etc.). I find greater satisfaction navigating off local knowledge and compass bearings, although it is nice to have a gps track to hand as a second voice of reassurance - particularly in testing conditions).
