sure - we all have different views of events but I think that some of your criticisms were based in lack of info which is why I posted my comments.
as I've done the Vit 5x, and Dambsuter 2x (plus reffed one as well) it's an event/location that I have some experience of. I think it's still one of the best around but it does have some faults - no event is perfect.
Seren - to answer a couple of your questions as I know the Vit/Dambuster and the organisers well
The campsite is managed by Anglian Water - nothing to do with the organisers of the event - so your criticisms need to be aimed at AW not Pacesetter. But for your info, toilets are just outside the campsite (by the cafe) and open at all times; there are showers for athletes to use in the Sailing Centre - free of charge.
Food at end - they supply what sponsors provide. There is no obligation to provide what you want.
Locals on course - it's always been that way and no different to many other events. The paths around the lake are open to the public so they have as much right of way as the racers (and sheep!).
Swim - again, it's always been a 2 lapper (or one for Dambuster) - yes, it's rocky but then so is Bala and many others I can think of. Matting washes away under water. They are restricted by AW to how much of the lake they can use for the swim which is why it's a 2 lapper, not a big single one.
You didn't enjoy it - fair enough - but you need context to your comments.
Big Foz - the manky water is one of the features of this event - everyone moans about the stones, weed and goose shit, but it doesn't seem to stop the event going ahead!
you can do breaststroke whenever you like at whatever distance but you will find that over longer distances crawl is more efficient and less energy demanding - perhaps a reason why you don't see swimming competitions with breaststroke events longer than 200m whereas crawl goes up to 1500m in a pool and much longer in open water.
and as said, wetsuits are not best with breast stroke as the leg kick has to fight the resistance of the neoprene which is thicker on the legs to aid buoyancy.
