Jim, taken from draft document -
"The use of GPS type equipment is not an acceptable substitute for traditional navigational aids and their use, along with “walking poles” or sound equipment that restricts hearing, is viewed by the FRA as contrary to the ethos of the sport. Race organisers are, of course, free to ban such equipment from their events."
Go for it!
