Tom - Thanks, certainly an option to have a look at on the day and pick up some of the route.
Richard - I think the start time should be the same 9am this should give us time to get there maybe have a coffee and pick a good spot.
I remembered in work last night a club run Rob took us on a few years back when we went to Usk. Ive had another look and used some of the roads we went on so this route might be better.
