Stomach problem is the common issue with most of the runners. Most of the marathons face this problem and do not share this bitter reality. It has been researched that 30 to 90 percent of endurance athletes face stomach and bowel distress problems during distance running and this percentage is speedily increasing with every passing day.

To avoid such problems you need to adopt the following tips:

1. Before the event begins, you should avoid taking high fiber foods.
2. If you have a history of stomach problems, you should not take aspirin and ibuprofen while running.
3. You should not take such drinks which are made from fructose.
4. You should avoid dehydration. During training, try to take as much fluid as you can. Take water pills rather than water during running.
5. You should not overly take sweetened drinks. Remember, more sugar means you are increasing your stomach distress.
6. Practice new nutrition if you had food problems in the past. It has been discovered in studies that nitrate supplements are really good for lessening stomach distress during exercise.
