I'm an English rider. Apart from Trail riding, I love jumping! The adrenaline rush, the thrills, the flight... I'd love to try also Cross country, and I'm preparing my boy for Driving - he's going to pull a sleigh for the first time this winter. We do everything bitless.
(I'm not a terribly good jumper, but I'm training to improve)
Oh, and Trick training. I don't know if it can be called a discipline, but we do it on a daily basis, and both of us enjoy it. :)
