Made a massive hash of this last year in the fog and snow on my own at the back. Thought I was doing well as the footprints were going my way then completely lost them on the route I had planned (taking a direct bearing to where Grindslow Knoll path joins the kinder edge path- not recommended) . Its my third year of recceing this and only now is Kinder revealing its secrets. That's the greatest thing about this race so much route choice. Like others I would recommended a linear recce from Crowden to Edale- logistically a bit difficult to organise but well worth it. Before that everyone goes pretty much the same route and not much choice.
