This question is about Running
Running immediately after eating may cause gastrointestinal distress, including cramping, nausea, and diarrhea, however, some people find that they can tolerate a small amount of easily-digested carbohydrate (such as 4-8oz sports drink or ½ banana) before running. In general, it is best to wait 3-4 hours after a large meal or 30 minutes – 2 hours after a smaller meal or snack before starting your run [ 1
