definitely stupid, not sure about fast - fast....
Oh man, that's a long way to go to lose sight of where you're at as the finish approaches. (I only had to cycle into town to miss the penultimate control last November.). Some tricky route choices to be made from #4 to #20 too, looking at Routegadget
it's a very good area, and there were some interesting legs (most of which i got wrong), but some of the mapping and planning was a bit iffy - several others missed that last control.
And Martin Ward did indeed have a comedy route to #1 back along the walk to the start and the wrong underpass.
Fair play to him for posting that blunder on RG though :)
