You're confusing me with the OP. I'm not riding it.
Lot's mate. Lots and lots. Been there, done that. Marshalled at plenty as well. I also marshalled at a sportive once - saw plenty of riders out on the course who hadn't entered - but nobody cared.
Not confusing you I suggested you organise a sportive and see what is involved.
Respect, that is what drives me to not ride on roads where an organised event is going on, as I said instilled in me years ago, unfortunately lacking in many parts of life nowadays.
