In my experience as an exhibitor and a judge, a large number of the required classes don't even fill, depending on the number of horses entered, obviously, or the classes might be very small and go quickly. I've been to one day shows that start at 8:00 a.m. and finished before 5:00, and others that finished at nearly midnight. It's kind of daunting to see 110 classes listed for one day, but it's definitely do-able.
Edited to add: I might have misinterpreted your request. I wonder if you're looking to see the order the classes are offered in......
