I have to applaud the Ambleside stance and I also notice 3 county tops have precluded the use of GPS for navigation this coming weekend though it is allowed for recording and safety.
Fell running has always been an inclusive event. Yes we should embrace technological advances but until such time that GPS devices are affordable by all, commonplace, and above all, have no safety issues in terms of reliability over a map and compass, they should not be allowed for navigational purposes.
