I have learned that you don't just train your body for these long rides, you train your stomach too. So now we've got a year to find a sports drink that you and your tummy like (any suggestions, grrls?) and take it with you even on rides where sports beverage is provided.

I have read that the plastic cannisters that 35 mm film come in are about the right size for one large bottle (or two if you dilute them) worth of sports drink mix and easily fit in pocket or under seat bag...at least that's what I'll tell the folks at the airport ;-)
