Oh heck no you are not too old to show! At the horse shows I work at and have gone to view, there are a lot of people past 50! I know there is one woman that is always top for points who has to be at least 60 and she goes out there and rocks the show. I went to a barrel show where in the senior division, the 15.1 second score belonged to a man in his 70s. You are never "too old" to show as long as your body and mind are in good form dear! <3
Absolutely not! Back in the day when I showed and took lessons at a hunter/jumper stable, the mom of one of the girls that I rode with, who was in her 30's, was just starting to get into riding and showing, and everyone thought it was really neat!
Largest division on the circuit I show on, are Senior and now there is a growing division called Senior Select, over 50. At 30 years old, too old to show? Yeah, sure, go stroll around with your walker and sit in the stands and watch, LMAO!!!
I'm 36 and have never been in a show in my life. Been rideing forever but never shown. I'm thinking about going and getting some showing experience in some open ranch horse competitions just to get some experience. Mainly if my daughters decide to try their hand at showing I have some first hand knowledge. I'll just feel a bit odd out there. I don't like being the center of attention at all. I prefer to stay below the radar.
I think showing as an adult is so much more satisfying; I can plan things out, I can be organized and relaxed. As a child, it was always like "Oh, we're 30 mins late, and of course Sara forgot her breeches... "
Now, if I think my horse needs to come way early and look at scary things, I can plan that into my day. As a child, I wanted to win; but now I just go to have an outsider judge my progress and give me some new ideas to build on; it's peaceful. I have the funds to really make him look great, etc. Its way better :)
