In another thread rickangus asks My best description is that a lot of people come and camp on the Racecourse. In days gone by I assume people largely got there by train and bike, but increasingly people seem to drive up in fancy cars and camper vans. At the rally there's a couple of big marquees with exhibitions and various stalls selling (mostly) cheap cycling gear, and usually a few crackpot inventors with some new gadget that they think will revolutionise the cycling world. The CTC organise a myriad of events (rides, competitions, etc), and there is always the "saddlebag" sale where attendees can flog of bits of kit to each other. Lots of people clearly find it a great social occasion, but as I live nearby I tend to pop in for an hour or so, and miss out on all the exciting social activity. I am sure that there will be other forum members who can fill in some of the gaps in my description - e.g. I have always wondered you what goes on after dark.
