No advance details this time.
As a general indication of the area concerned it's between 04 and 08 horizontally and 84 and 89 vertically, which contains a lot of possibilities but the points themselves are definite features, so it's certainly not a test of micro-navigation, more a question of route choice and map-reading.
There are five checkpoints and at each one you'll need to write your answer in a box at the foot of the map – HENCE A BIRO WILL BE ESSENTIAL, as will a weatherproof poly bag or map case.
Also £1 voluntary contribution to Andy's map duplication expenses would be very much appreciated.
The optimum-ish route would be about 8.5 miles with 2,000 feet of climb, but the distance could be diminished and the height increased, or vice-versa, depending on your individual preferences.
Start times will be from 10.00 a.m. but it might be an idea to arrive somewhat before your start time in order to give yourselves some leeway for route planning !
