Average jump depends on the breed. For TBs I'd say average is 80"ish but for example my Selle Francaises, the average would be around 76"/77". Times have definitely changed; I'd say horses jump higher now because of all the super horse blood. But I could be wrong :3
Natural horse jumps range from 72"- 83" I believe, depending on how strong the lines are. How well horses do seem to also depend on the person breeding them. Like in my barn, my mares ALWAYS do better than my stallions. Mine also seem to peak really late. Like a few will peak at 7-10 but most of them dont peak till 13-19. Once you know the breeding you are working with they seem to adjust to the person breeding them. My ITBs has two Natural 80"+ jumpers. And this is the first of my breeds to hit over 80" since before the jumpoff update.
I'm going to wait on getting any horses right now, but thank you guys for the offer, I appreciate it!
Chesy- Aw that's sad. Do you know if they're still active on DA?
And good to hear. I'm actually doing pretty good, have had a lot of hard things to deal with in the past year but things are really looking up now :)
