My thoughts would have been to coincide with the BVS L2B, usually held in July each year - but for 2010 I think they are shifting it to September which could clash with Brooklands (my favourite event).
Same as happened in 2009, the events list for this year has filled up quite quickly and I expect there are still a couple more meetings/runs/shows yet to crop up.
In a strange way, having too many events on the go is quite a good thing as it shows c5alive is continuing to do well
