Tag: Pre run diet

Between 30 and 90 percent of endurance athletes report gastrointestinal issues during exercise. A key factor is a diet high in fiber consumed too close to a run, which is why no fiber before run is a common strategy.

Protein takes significantly longer to digest than carbohydrates, a crucial factor in pre-run nutrition. This slow digestion is the primary reason why too much protein before running can cause discomfort and negatively impact performance, diverting your body's energy away from the muscles and towards the gut.
