Sulis--check your PMs!

And Lifesgreat...as long as you're doing SOMETHING you will be fine for CH. My fastest century last year was my first one (in March) for which I had completed very little on-road training, but I had been skiing a whole lot and was religious about doing pushups and wall sits. My butt complained a little bit as I hadn't spent 5+ hours in the saddle since the previous year but other than that I survived just fine.

I'm still leaning toward the Zion Country ride as the CH may interfere a teeny bit with my schedule. Not certain yet. In any case, if it looks like I can do the CH, I'll PM you and perhaps we can meet!
