Running a marathon is a remarkable achievement that challenges both physical and mental limits. Understanding the physiological demands and changes your body undergoes during this endurance event can help you prepare effectively and ensure a successful and enjoyable marathon experience. From training and race-day strategies to post-race recovery, being informed empowers you to take on the marathon challenge with confidence and resilience.
