Up until the day before a trial I train as normal (which lately has been not much at all

). The day before the trial I run Mike Lardy's pre-trail triple. Dennis Voigt calls it an all-in-one triple.
Run as singles.
Start with the long gun hidden...
Shoot a middle distance flyer converging with a short bird with the short gun out.
On return, with bird-in-mouth, throw the short bird and retire.
On return, throw the long bird and retire.
The all-in-one is a fitting name because you work on many concepts you will likely see in a trial like...
Look for the long gun past a shorter stand out gun and don't head swing.
Check down on a short retired in front of a tempting flyer after running long.
Drive long, tight off the back side of a flyer station after having just run a short mark.
I like to do this before both HT and FTs, just shorten things up for the HT.
The day of a hunt test I like to do Dennis Voigt's come in drill with my high drive dogs. It gets the dogs in a more compliant frame of mind by sending them toward a bumper, stopping them, bringing them in several yards, and casting over to a different bumper. I finish the deal with disciplined casting with the last bumper.
