I hope you two are keeping hydrated. The dehydration one can experience in the South during summer is insidious- especially if you are not ATGATT. Just stopping every hour and drinking will not do it. Water is absorbed into the blood quickly, but absorbed by the tissues (where you really need it) much more slowly. So you can drink a ton every hour, pee clear, and still be dehydrated, losing electrolytes as well. (I read that whereas a dog or horse can hydrate in minutes, humans can take up to 16 hours to completely rehydrate after dehydration. I think we have probably ruled the water holes, or stored water in camp, for a long time during evolution.) You really need a few small drinks every 10-15 minutes, and keep it up. It will make a HUGE difference in how you feel. Not to mention keeping you alert and safe. The most practical way to do this without stopping is with a Camelback or Platypus or generic WallyWorld equivalent. Plus the reservoir holds a lot of water for later camping! BTW, The Iron Butt Association has an excellent article on hydration on their website, and I encourage you to read it. It's a shame you didn't route through Madison, WI. It's a great place that is a very nice alternative to the mundane sameness reality of most of America. Bicycles and two wheels rule, at least in the summer, and studded bicycle tires and small cycle tires are sold a lot for the winter. I have seen many bikes the size of yours plowing through the snow in the winter. Plus you could experience great beer. And more great beer. And have a place to stay. Enjoy!
