Are the races usually held on the established trails there? ( Limeburner & Beater ) or are things mixed up a bit?
Not sure I'd fancy the Bracken Pit on a CX bike. Everything else would be ok.
Usually a mixture of the existing marked trails and some other unmarked bits in my experience. That pit is definitely doable on a CX bike - I've seen it done. Admittedly by someone with far more experience on a CX bike than me. It's easier now they've put those rocks in place than it was before, when it was just a wall of sandy soil you had to scrabble up. With those rocks in place it's really just a question of carrying enough momentum to take you up and over the top.
