I suppose it's time I proffered my view on the matter.
I think among the wider fell running/walking community, virtually everyone would expect anyone claiming to have done the BGR would give a time in under 24 hours.
I think I would be correct in saying, that of the individuals who attempted the BGR, got back to the Moot Hall, but failed to make it in under 24hours, virtually none would say they've done the BGR.
I have immense admiration for individuals who, through various reasons, successfully finish the route of the BGR knowing they have missed the 24 hour deadline. But for me they have only completed the route and not the Bob Graham Round.
