I had a week of telemark instruction in Les Contamines with The Telemark Ski Co. Any pretensions that I might have had about my telemarking ability were quickly demolished on the first morning. By the end of the week I was feeling a lot more confident and, while still fairly crap, I know what I need to work on.
Booking on a course goes against the grain a bit for me but it was definitely money well spent. Excellent instruction from Ian Johnston and a friendly bunch of fellow students.
