Funnily enough, this OS grid ref was a standard feature on the old Garmin 310xt, which you can now pick up on e-bay for less £50.
Personally I think (blindly) following a breadcrumb trail in a race, either on a phone or watch, crosses the ethical line but I wouldn't be agin using the grid ref feature - unless the RO ruled against it of course.
