Discussion: Did you think about using your compass

For that 150m leg and just run to the top of the hill?

Yes I did ;). I wasn't quite into the map at that stage, it was silly I must confess... I blame myself, but I also have some criticism for the mapper :P.

Yeah holly is never well mapped in this country for some reason. Wimbledon Common and the new first have the same standard.
Distinct veg boundary symbol is not used but you can only really trust it if it's middle green to navigate off.

I don't do well with the mapping of green. I assume that you went straight on a lot of legs whereas I tended away from the green. But the runnability on the roads wasn't great either with the mud so I'm pretty sure straight was pretty much always better.
