Nancy, I am training for a marathon. I know I should drink on my long runs but where I run, no water is available. Is there any way I can super-hydrate so I don't have to drink on the long runs?


No, you cannot super-hydrate. Your body is like a sponge and can absorb just so much fluid at one time. Then, it starts to seep. You can start your long runs fully hydrated by drinking plenty of fluids the day before. Drink enough so your urine is pale colored and you have to urinate at least every two to four hours.

On the day of the long run, drink plenty of fluids (water, juice, even coffee or tea are OK) up to 1.5 to 2 hours before the start of the run. Then stop drinking, so you’ll have plenty of time to eliminate the excess and hopefully avoid the need for an unwanted pit stop. Within 15 minutes before you start the long run, drink again to get water into your system.

To enhance fluid retention on the day of the long run, eat something salty with your pre-run breakfast. This will help keep water in your body.

     --Add some salt to your oatmeal.

     --Enjoy some chicken noodle soup.

     --Eat a bagel with peanut butter.

     --Have salted rice or potato.

These foods offer far more sodium than you will get from any sports drink. (Compare labels and you’ll discover 8 ounces of Gatorade has only 110 mg sodium, whereas a Thomas’s bagel has 400 to 500 milligrams sodium.)

I also suggest you hide bottles of sports drinks or water along the running route. Part of training is to train your intestinal tract. For you to go from drinking nothing during training to consuming fluid every 20 minutes during the marathon might be asking for transit trouble. Be wise and practice drinking during the long runs. You'll not only run better but will also recover better.
