Wow – thank you for your brilliant suggestions!
I think we'll try Ed Oxley and Gisburn/Lee Quarry for now, but I'll treat myself to a session with Jedi later in the year
Must admit, I've been put off MTB courses by a bad experience on a Beginner's course a few years ago. I don't want to be too specific, as I'm told the instructor has improved since then
However, the location (a popular MTB spot) didn't really have the right range of "challenges" for instructing. And the instructor was determined to impose his standard "syllabus" on me, even though I was struggling. Also, I'm not very good at just watching then copying, and he didn't seem to like explaining things to me first
Perhaps he also remembers me as a "bad experience" . . . but it shouldn't have been like that
Anyway, thanks for all your ideas!
