How many shows do you show a year?
Counting unrated schooling shows and B/C shows, I get to about 12 - 15 a year, with about half being A/AA rated.

How far apart do you break?
At most, about a month between shows.

How long are they?
Usually even the unrated stuff lasts two days, so typically from 2 (unrated/C rated) to 5, technically, for the AA rated shows, although we're usually there for at least 6 days, to give the horses a day to settle in.

How many classes do you show a day?
My mare will usually do two divisions, plus warm-ups when offered, so an average day at an AA shows she'd have three trips - warm-up, plus two trips for her division. A really full day would might have four trips, if there was an extra classic round.

Are they spread out?
We'll usually only have a couple other horses go in between each of our trips. Sometimes for the second round of a classic we'll have enough of a break to go to the stalls and come back, but it depends on the show, oftentimes we can just do our second trip for the classic shortly after the first. Additionally, we'll often have a fairly large break between her fences trips and the hack, in which case I'll take her back to her stall.
