For the past few years, Shipley has been used as the closing round for the series. So its usually later in the year for the National Trials Cup to be holding a comp there.
I'm not sure what the Tyke Trial folks do, or what they're all about but those guys might hold one there too?
For better or worse, it seems like trials in the UK is leaning more towards more of a Euro style set up of man made sections with numerous "Academy" locations being used. "Better", because its not a exposed hill side. "Worse" because, as Ali and Mark mention, you don't get that undulating ground and you don't develop that bike control you need to ride these places. What you will learn however, is how to Up to back from a static hook. So it almost turns into, who can go the biggest, instead of who is the best bike handler. I'm not having a moan btw. Im all for any type of venue, and enjoy riding places like Radical etc..
