Ya. Great. See my comments on small schooling shows above.
There’s some video on youtube that shows the Brownland derby you mentioned. Trotting between rings. Not cantering or jumping in/out of a ring.[/QUOTE]
The OP hasn’t said what type of show or the specific show she’s attending. So I’m not sure how anyone can can say with any certainty what will/will not commonly be expected in the class she’s entering. You keep saying you’ve NEVER HEARD of cantering/jumping out of rings in derbies. People keep giving you examples of shows at different places/levels that do it. We have no idea if OP is going to shows like the ones you’ve seen or the ones we have. So continually telling her “you’re not going to have to do that” makes no sense to me… unless you know something specific about the show she’s attention.
The show I referenced (in response to the assertion that low level derbies NEVER have cantering/jumping in/out of the ring), is not a fun show type show (I said it was local, not hokey poke) with pole bending and doubles bareback etc. It’s a local series that is very well attended, runs on USEF rules, with typical hunter/equitation classes run to USEF specs, and holds is a year-end $2,500 hunter derby. Complete with cantering (and jumping) in/out of the rings some years. At levels 2’3 on up.
I didn’t mention a Brownland derby, other people did.
