Hummm interesting,no gps allowed.
i think its a stupid rule ,safety of the runners should always be a priority.if you can get from one checkpoint to the next no mater what navigational device you have i cant see how you would gain an advantage over anyone. after all ,be it a compass or a GPS you still need the skill to use it effectively.
i know that a thread has been on this issue before,and i still think that the rules should adapt with the technology after all the compass as we know it was once a new tech device. also this is not an orientiring event but a fell race
