Well, I am cogitating on it! If I felt I could manage it, Saturday would be my preference (which, as it happens, will be my birthday - a long hard ride provides lots of time to contemplate my ever-aging body! )

I'm hesitating primarily because, climbing gears notwithstanding, the "1 mile : 100 ft climbing" ratio is tough for me (e.g. 48 miles, 4800 ft of climbing is twice the Pinehurst loop, which about killed me a couple of weeks ago), and I still have this very unpleasant tailbone pain to contend with...

Hmm - I will think on it and post back later today or tomorrow.
