I took a horseback winery tour as part of the surprise Valentine's Day weekend away I organised for my girlfriend. It was fun but of course I was pretty nervous and not being a cyclist etc I found it difficult to get a good sense of balance. I was put on quite a tame horse but I still struggled a few times to control her and keep her from trotting. Fortunately neither of us fell off our horses! And yes we were both sore the next day. I expected sore legs, but was surprised to find my ribs were also very sore from all the very careful leaning.
