Yeah it shouldnt be too bad, we've been hacking for years (and I mean the Aus show type, not the trail riding type, and have done a bit of this and a bit of that but never combined training and hardly any jumping)
Staying relaxed is probably the main thing as you said, he gets a bit excited when I take him out and I get nervous too
They only have one combined training comp a year so I thought i'd jump in and give it a go.
As for the facillities, yeah, I have practically none. I ride in a small paddock dodging trees and such lol!
Thanks though! I'll just get there early and allow plenty of time for warmup.
Oh, also, do I need to plait up like you would for a proper dressage day?
