I did a novice day last summer, and you shouldn't need warmers or any other elaborate gear. They are very rider friendly. They do break you into groups by level (self evaluation). The first few sessions a very slow, then as each group gets comfortable, the instructors up the pace a little. Each rider gets some individual evaluation by the instructor and you can ask as many questions as you like. I thoroughly enjoyed it, and will be back (hopefully on the July 18th).
