I've just entered the Anniversary Waltz and while I did run round the course recently, I've got a terrible memory. I was considering the following as a navigation aid in case it's really foggy:
- a little list of the bearings for exit routes from each peak
In my bad-weather fellwalking experience it's getting off the tops in the right direction which can be the tricky and time-consuming thing, with a force-9 gale disrupting things etc.
This way, you can just set your compass and off.
