I put that badly.
Where do I find them if starting at the organisers main web page? That is as your average punter reading bumph prior to filling in a form. I have searched all over the site (hence registering, thought would be revealed in that process - as in tick to say have read this).
I can't see anything at any menu at http://www.prudentialridelondon.co.uk/Prudential_RideLondon_Home.htm
I did toy with the issues of how the condition of entry can be enforced, putting aside the likely potential unlawfulness of them in the UK*. As some cyclists who are not event participants are likly to be toing and froing with daily life around bits of the 'course'.
However the event roads will be 'closed', which presumably means that non-participants can be barred and removed! That could lead to some interesting news coverage... "Sikh on an electric bicycle carried from the Prudential RideLondon event after refusing a senior steward's request that he comply with the terms of participation. Sir Bradley Wiggens said..."
*One of life's little serendipitous moments was when I was checking I was correct on the (UK) law on motorcycle helmets and turban wearing (1976 exemption), possibly analogous, and came across this March 2013 Australian report.
