As I said, we all cause erosion, it's just that we "accept" that done in the past whilst at the same time trying to manage what's happening in the present. We all have a view in our mind's eye of how the landscape should look and get upset when it changes but look at photographs of the Lakes from a century ago and it's vastly different. There's new roads, buildings, etc. the Penrith - Keswick railway is no more and so on.

We get fairly regular requests to include the BGR in books along the lines of "The World's Best Adventure Races" which are always declined - see this page , because of the problems the increased footfall (and behaviour) would bring, if you aren't part of the running community you are less likely to be concerned with the consequences of your behaviour and actions.
