Running a marathon is a remarkable athletic achievement. Whether you’re a world-class runner or a beginner, running a marathon is a serious commitment. Training is an essential, long-term process, so give yourself at least 3-6 months to gradually build your endurance, or longer if you’re not already in good running shape. Your body will need lots of fuel, so eat a high-carb, high-protein diet, and drink plenty of fluids to stay hydrated. Above all, remain positive, have fun, and be proud of yourself for taking on this intense challenge!
