Has anyone on this forum done the Karapoti Classic? I'm planning to do this next year as my first big event. A little nervous as I'm currently unfit and don't yet even own a bike.

I have borrowed an old Giant hardtail and am hitting the trails at the moment . I am also raising some funds [ see signature below] and am tossing up between a GT idrive and a Jamis Dakota. Any thoughts on either of these?
