Marathon training involves a structured plan to prepare for running a marathon, which is a long-distance race of 26.2 miles. Training typically includes a mix of long runs, speed workouts, and rest days to build endurance and strength. Runners often follow a schedule that gradually increases their weekly mileage to avoid injury and improve performance. Nutrition and hydration are also crucial during marathon training. Runners need to consume a balanced diet rich in carbohydrates, proteins, and fats to fuel their bodies. Additionally, staying hydrated before, during, and after runs helps maintain energy levels and supports recovery, making it essential for successful training.
