Isis was incredibly sore the day after the trail ride. We both were; although she certainly was worse off. My legs were sore, but not bad. Her entire body was sore. She carefully walked around, picking her way through the paddock to walk over to me.
I rubbed her down with liniment and walked her in the ring for 15 minutes in hand. Enough time to get some exercise and stretch her muscles without working her too hard. She is still very lame.
