( First ever post - welcome all !)

It seems to me that making a mobile compulsory on fell races is completely against the spirit of self reliance that makes ours such a light-touch sport for individualists. If this goes unchecked, then they could become a standard item in kit checks and our sport would be the poorer for it. If you've ever talked to someone lost on the moors who haven't a clue where they are (in the unlikely event of a signal), you get some idea of the limitations of mobiles and an understanding of what 'false sense of security' means in practise!
As a long serving mountain rescue member I've noticed a growing trend where people who would once have got themselves out of situations (like being simply lost, in good weather) now rely on mobiles to call for help.
This situation looks like a knee jerk reaction to last year's extreme weather on the 'Skyline race , perhaps a better 'safety ' solution would be to alter races to suit the conditions eg bad weather alternative/ shortened courses.
