I got to ride a TWH for some basic riding lessons I took - it was so awesome! After almost an hour of gaiting and cantering practice I wasn't one bit tired (like I am after riding my bumpy trotting mare for an hour, haha!). Nice, smooth ride, and even though all of their gaits are faster than those of an average horse the extra speed wasn't frightening at all :)
I really want my next horse to be a gaited breed (leaning towards TWH or Rocky Mtn horse).
A question about the TWH shows - why do the riders sit in the position they do (legs long and in front, upper body leaning forward, shoulders hunched)? I've only ever seen it in TWH shows.
