There were some stores along parts of the route... but I don't remember the mileage where these were at (it was only my second time in Tucson). Maybe a Tucson local, or a check with the local bike club, could help with that. Real gatorade does beat the powdered stuff, doesn't it.

I do remember some real food on the ride -- about 10 miles from the finish my friend got the last PB&J sandwich they had out. So maybe I was so slow I missed all the good stuff?
