bring sunscreen anyway. I have no knowledge of where you are going, and am too lazy to look it up right now. But if you are on the edge of the water, the sun will bounce off the water and up right back at ya.

And bring some kind of flipflops or similar flimsy sandals. With that much riding you might want to give your feet a break at rest stops, and you will want to rip off your bike shoes when you finish for the day.
