I'm on a message board for people who like to read and write. Somebody is writing a fantasy book and wants to know if it's really possible for two people to ride a horse when one of them is unconscious. (OK, I guess the unconscious person isn't really "riding" lol). Someone there who has horses said it would be possible, but I wanted to know what some more experienced horse people thought. How long could a horse gallop carrying two people to begin with?
