DH started riding at 56yo, went on to show H/J and Event w/me.
He'd be riding still, but sadly I lost him at 70yo.
I have 2 horses at home and take care of my 5ac farmette by myself.
Hope to be doing it still, well into my Golden Years

Well, Miss Connie Reeves, my mother's camp counselor in the 1930s, might still be riding had she not been dumped at age 101 by her 28 yo horse (died of cardiac in the hospital a few days later, she had broken some neck vertebrae but was not paralyzed).
There exists a cool video of Miss Connie but don't have time to dig it up just now, I have posted it in other threads in these parts.
The oldest rider at our barn is 67 or 68, and he takes his Tennessee Walker on 10+ mile trail rides a couple times a week.
The oldest student I've taught was probably in her mid-80s. She had hunted and shown a lot in her youth, and just wanted to putter around at the walk and trot. She was a really nice rider, and the 25 y.o. schoolie that she rode (who'd been a show horse in his youth) made a great pair. She used to tell me all kinds of stories about her hunting days when she took her caffeine-free Diet Coke breaks. And she used to come with her "gentleman friend".......who was noticeably younger than her. Awesome lady!
My BO is 82 or 83. She did her Century Ride last year and still rides 3 or 4 times a week on an approx. 3rd level horse. She has trained several horses to FEI levels and is a recognized judge, I think an "S," though I understand she may retire from that because she and her husband want to travel more!
FWIW, I bought a 2.5 year old when I was 62 (what WAS I thinking?!?!?). It was a wild ride for a few years, but he's settling down now, and I'm 67.5(that is, I've survived so far!) . A 16.2 h.h Araloosa can be a very exciting ride! He's a pretty fancy mover and we are schooling 2nd level. I hope to show him 1st level in 2013. Lack of $$$ and a broken arm prevented us from doing that this year.
