riding in a group is a good experience, just use a little common sense, leave a decent gap, if you overtake, move over and leave plenty of gap on the width, when I ride alone I loke to get a bit of a move on, but when riding with others, I adapt my riding style to suit everyone else, group riding isn;t a race, its a fun sociable day out.
All being well if I can make this meeting, by the time I get to hawes, I wont want to go for another ride out (hawes is a fair run for me), but It would be great to meet up for a chat and a brew, before you set off.
John, is there any chance we could meet at the Rocket centre, near you, and then head up through Clitheroe towards Skipton, as a blat up the M6 to Lancaster is the last thing I want.

Im not a gynecologist, but I dont mind taking a look.
