To contour round hills at a set height instead of going over the top? Although I don't think you NEED the contour heights but would be helpful as you then have a rough idea at the height you are going to contour.
p.s don't mind altimeters in races as sometimes they can confuse said owner and I find a person competent in a map and a compass will tend to get the better route than someone playing with an altimeter.
I'm sweating on the issue as to whether I have an entry - being a skin flint I posted my entry off Sunday night by 2nd class post only.
I wonder if the new Housing minister's 2nd name is "skin" what with her new policy suggestions made yesterday?
The KIMM has sometimes left off contour heights in order to reduce the advantage of altimeters, but in practice most navigation can be done using relative heights - i.e. I need get 100m above the col before I start to contour. As long as you know the contour interval, the absolute height is actually pretty irrelevant.
Having said all that, I dont think I would bother with an alti in a fell race.
My wifes watch was an altimtere one, and we had countless barnies when she'd say oh we're at x height, and I'd ask when she last calibrated it, and it would be a few weeks back :-)
Amazing when you use one continually through the day, when fronts are moving through, how much the height will vary due to the pressure differences.
My Race Map from last year's Skyline has got the heights of the contours marked on - they're imperial as the map is based on non-copyright (more than 50 year old) OS mapping, but I've just spotted that the height of Brown Knoll is marked as 2503ft on the Race Map - getting to the top of Brown Knoll would be even tougher if it was really that high, and it would be the highest point in Derbyshire. My old 1inch map of the Peak District says it's actually 1866ft!
I agree with Dom - the Race Maps are a useful guide, but not a substitute for an OS/Harvey's map.
ive lost my map again:(
andy ????? any chance of a copy
sorry just realised i ate it last year as my fingers was to cold to get my snap out:)
