Carbohydrates are the body's primary source of energy for physical activity.

Complex carbohydrates provide a steady and sustained release of energy.

Glycogen Storage and Depletion

Glycogen is a form of stored glucose in muscles and the liver.

Prolonged or intense exercise can deplete glycogen stores, leading to fatigue.

Consuming carbohydrates before a run helps replenish glycogen stores and delays fatigue.

Protein and Its Contribution to Muscle Repair and Growth

Protein plays a crucial role in muscle repair, growth, and recovery.

Including some protein in your pre-run meal can aid in muscle maintenance.

Healthy Fats for Sustained Energy

While carbohydrates are the primary energy source, healthy fats can provide long-lasting energy.

Hydration and Its Impact on Performance

Dehydration can lead to decreased endurance, muscle cramps, and overheating.

It is importance to pre-hydration in preventing dehydration during a run.

Foods to Avoid Before a Run

Some foods should be avoided before a run to prevent digestive discomfort and ensure optimal performance. Here are the foods should be avoided:

High-fiber foods:

High-fiber foods like beans, lentils, broccoli, and bran cereals can lead to gastrointestinal distress, including gas, bloating, and diarrhea, if consumed too close to your run. They take longer to digest, and the movement involved in running can exacerbate these issues. It's best to avoid these foods in the hours leading up to your run.

Sugary and processed snacks:

Sugary and highly processed snacks, such as candy, soda, and sugary pastries, can cause a rapid spike in blood sugar levels followed by a crash. This can leave you feeling fatigued and low on energy during your run. It's better to choose complex carbohydrates for sustained energy.

Heavy, greasy, or spicy meals:

Heavy, greasy, or spicy meals can lead to discomfort, heartburn, or indigestion during your run. These foods can slow down digestion and increase the risk of gastrointestinal issues. Avoid foods like fried foods, rich sauces, and spicy dishes in the hours leading up to your run.

In summary, choose easily digestible, balanced meals or snacks that provide a good mix of carbohydrates, protein, and some healthy fats. Avoid foods that may lead to digestive issues or energy crashes. Experiment with different foods and timing to find what works best for you, as individual tolerance can vary. It's also essential to stay hydrated but avoid excessive water intake right before a run to prevent stomach discomfort.
