I sent an email to the organization and this was their reply for the fun gundog day on the Sunday;
The fun day will consist of three maybe four different simple tests to accommodate wildfowling dogs, a small walk to heel with a simple mark, another with a splash in a pond and two other tests that we shall set up on the day, the demonstration will be a few dummy's launched off a dummy launcher and hopefully retrieved by a little more experienced dogs. nothing too serious.
Sounds like fun, and a good day out if the weather is good.
Haven't heard of it before, but the Sunday sounds really interesting - I'll have to see if I can persuade myOH (I take it we will be allowed to watch with out own dogs if they are on leads..... and that show cockers won't be barred entry 
)
I'm sure you and your cockers would be more than welcome.
I quite fancy it as having not long moved house we decided not to go on holiday this year; so we could do more round the house, our breaks this year will be to the game fairs and events like this one. Let me know if your going, so I can look out for you and your cockers
