I like the idea in general, and agree with other posters regarding making sure anything showing wise "meshes’ with the regular training and showing programs.
Love the idea of working on rider fitness (and that you have a warm spacious area for it
). I would definitely extend this beyond the word “fitness” (which frankly scares some of us non-gym people) to include things like “body awareness” or “rider alignment” training. It’s all so valuable, and I’m sure you could find lots of great guest lecturers on everything rider.
Don’t forget the horse in your fitness work either. Again, good for every horse, but especially with brutal winters, it can be great to have some clinics/talks on productive things you can do when it’s just too cold/miserable to ride (yes, even with an indoor, it gets there).
Love the idea of an “ask the vet” night. You can look on the horse care forum for topic ideas!
With regards to the shows, like others said above, a lot depends on the current clientele and if you are trying to attract new. If most people already show with a trainer, you probably don’t want to cross over into that. (Could still do the booth of your guest speakers and meetings, if that is open to those outside the barn). If you are looking to get more people into showing, whether currently boarded at your barn or not, there are definitely some opportunities there. Things like “What’s in a show?” for total newbies, where someone experienced sits in the stands, etc, explaining what is going on, what’s being judged, how the day works, etc. “Show buddy” where someone not showing shadows a showing person (and, conveniently, can hold their horse or hand off a bottle of water if needed, though they’re not necessarily a groom) to get ready for showing themselves or participate where they can’t afford/are horseless. I know these things already happen naturally in a lot of barn communities, but since you are talking about a more organized “team” atmosphere, something as simple as a sign-up sheet might get more people coming out.
