To some extent, everyone is right in this debate. On an individual scale each of us has little to no discernible impact on the ground taken by the BGR but en-masse (and by that I mean each successive year's attempts) we are creating an impact.
If you've registered in the last year or so then you'll know that the confirmation email contains a précis of the guidance notes (it's roughly aligned with the indicated start time and schedule), typically it looks like this:
Thank you for registering your attempt on the Bob Graham Round. The registration is good for the rest of the year so if your attempt is postponed due to weather or other reasons then there is no need to re-register.
Please take time to read through the Guidance notes here: http://www.bobgrahamclub.org.uk/asse...s-may-2012.pdf In addition the following points apply to your intended schedule:
The Threlkeld changeover is close to peoples' homes so please keep the noise to a minimum. In addition the pack of hounds at the farm are likely to begin barking as you pass.
There is a fee payable for using the National Trust car park at Wasdale. BG support crews are not exempt.

Also, in an attempt to subtly try and limit the numbers on the fells, the ratification form has just two spaces per leg for recording the names of pacers/supporters.
Like John, I'm not a fan of big teams out on the fells but a balance does need to be struck with regards safety. Like Weetabix, two should be more than enough 
One reason the notes on my website give the Threlkeld changeover as being down by the A66 is to avoid noise around the residential areas however increased use here might upset the cricket club whose car park is so very handy
Certainly there's no need for any shouting or hollering at the changeover at the top of the road.
I don't think the "rules" need to be any more onerous but all contenders and supporters should show some respect for both the round and the people who live near to the route or who have facilities used or crossed by us.
