If you haven't already heard, MTBSkills.com.au have brought their courses, including a couple of women only courses, to Tasmania.
I don't know these guys at all, but I have heard some good things about them second hand, and I think that anything that supports mountain bike skill development is a good thing so wanted to give them a mention.
They've currently got five courses on offer between July and October 2012, so if you are in the market, give them a go ... then let me know how it goes.
