Marathon running is thrilling but can hide serious dangers, especially for older runners. Heart conditions, dehydration, and heatstroke can strike unexpectedly, even in those who seem fit. The tragic case of Taryn Armour, who died during a race, reminds us of these risks and the importance of regular health checkups. While many complete marathons safely each year, it’s essential to listen to our bodies and seek medical advice. Celebrating physical endurance must also include caring for our health and knowing our limits.
