He started his riders, all quite young - maybe in their late teens, over a line of cavaletti poles where the horses cantered. He talked about long strided horses going slower and shorter strided horses needing to move more quickly in order to clear the poles.
He next raised half of the poles into very low cross rails and sent the girls through again. Over the next hour, he slowly raised the cross rails into verticals and eventually two of the cavaletti poles became bounces. Ultimately, the horses were sent through a three line course with the verticals set to 3'6" and an oxer that was maybe two feet in width (hard to tell from where we were sitting).
What I really enjoyed seeing was how careful Karazissis was with the horses. Everything he did was to build their confidence, and as a consequence, the riders' confidence as well. He built the horses up from poles on the ground to the relatively lofty 3'6" verticals. The girls started with ground poles to help measure distance, but by the end, Karazissis removed even that aid to test their ability to maintain a consistent pace, adding or taking away a stride as necessary.
On a personal level, Karazissis was a very soothing presence in the arena. His instructions were clear and easy to understand, even for a non-jumper like myself, and his teaching style seemed very supportive. He used a method educators call scaffolding - build the student up, but keep lots of support in place. I probably liked him so well because his teaching style is very similar to my own trainer's style. I am guessing this must come from a classical hunter/jumper school of training. Just like in dressage, there is classical dressage that builds on a solid foundation, and then there is the hurry up and get it done group.
Not the best quality photos, but they'll give you a little sense of what the venue and riders were like.
More on the final clinic later in the week ...
