abracapocus, I hope you are carrying more than the one water bottle that I see on your bike. You might give a thought to a camel back and put it in the freezer the night before your ride. I would think your office would have a frige that you could freeze it for your return trip home. My daughter got me one for christmas last year and it works great. With water bottles I never drank enough water but with the camel back I drink about 60oz during a 35/40 mile ride plus what I drink at my Panera Bread. It also helps keep your back cool for a while. I still have ice cold water for about 3 hours into my ride.

I would also suggest Hammer Endurolyts especially during the summer months. Always enjoy reading of your adventures.

just my .02 worth, stay hydrated.....
