I am training for my 3rd marathon and in the past have gotten an upset stomach drinking sport drinks. I have read how important it is to keep you blood sugar up and would like to know if eating a sport bar (GU made me sick also) during the runs would be the same as drinking sport drinks? I have ran a training run of 18 miles drinking only water and eating 1/2 a power bar every 40 min for a total of 1 1/2 bars. This seemed to work well, is this a good way to go if I don't drink the sport drinks? Thanks Rich
Rich, sports drinks are unnessary from the point of view of hydration, if you drink water frequently and early (before you get thirsty). On the other hand, you are correct that blood sugar is important. Hitting "the wall" is a function of running out of blood sugar. You can avoid this by nibbling on a glucose type bar - the one we sell is an IDN product called "Glycobar" oddly enough. I also suggest that you carry some glucose tablets, and around the 18th mile, pop one or two. Glucose tablets are usually available form a drug store, they are usually packaged for diabetics, but the tablets are easily carried in a little pouch.
Another idea is to try different drinks - some might be easier on your stomach than others.
