For any concerned ROs out there, my advise would be to :-
Permit the race as usual
Study the final documents when they are published.
If there are concerns about whether you can meet the requirements, identify those concerns and alert the FRA to see if they are prepared to accept the measures that you feel are appropriate, even if they are not to the letter of the requirements.
If they accept, fine.
If they don't see if they offer a sensible option and then make your decision.
