Instructions

1

Eat less before your run. If you run first thing in the morning, for example, cut back from a bowl of cereal to a piece of fruit. Leave more time between your meal and your run. If you cramp up with a three-hour window, wait four hours before you run.
2

Drink more water before you run to prevent dehydration. Take small sips of water during your run, even if you don't feel thirsty.
3

Concentrate on breathing deeply. Start your run slowly and make sure your stomach expand when you breathe, a sign that your getting air all the way to the bottoms of your lungs.
4

Slow your pace. Running too fast may lead to shallow breathing, which leads to side cramps.
