Bolts on Broad Stand

[Bobert]

The only problem as an outsider that I'd have with this is the fact that the vast majority of challengers who complete the BGR are virtually reliant on their pacers / helpers in terms of route knowledge and navigation thus negating a large part of the "challenge".....

I'd disagree, from experience this is not what i have found to be the case.
In fact the exact opposite would be true.
