There are a number of events to celebrate this anniversary including this sponsored walk for the Morning Star. The Ramblers are encouraging people to send in photos of blocked footpaths.
By coincidence rather than design I walked up Kinder Scout during its 75th Anniversary.
I can't take part this year since on 22 April I will be be in London taking part in the Marathon (wishing I was somewhere, anywhere else, especially the lovely Peak District).
