ah - the old perennial pacing aids question. simply you are not going to ban garmins, bike computers, or other pacing aids etc as they are an accepted part of racing these days and like many sports, technology will always be one step ahead of the rules so even if you banned them, someone will come up with another way. as long as they don't interfere with other athletes races, or their enjoyment, or intefere with their hearing or concentration, then let them go.
I turned off the beep on my HRM as it was annoying me, let alone anyone else!
