Is a 15 year old Arabian gelding two old to run barrels or to train him how?
I need to know ASAP
It's hard to teach an old horse new tricks. You can try but I wouldn't expect too much.
I think you should let him/her just hang out in a pasture and relax
It's not to old, provided that he is in good health and has no joint issues. Just start out slow and never expect any spectacular times from him.
