What are the specific health risks of running a marathon without proper preparation?

Running a marathon without adequate preparation poses several significant health risks that extend beyond typical exercise discomfort. The extreme physical stress of 26.2 miles can lead to overuse injuries like stress fractures, tendonitis, and joint damage, particularly in knees and hips. More seriously, it can cause cardiac strain—especially in individuals with undiagnosed heart conditions—increasing the risk of arrhythmias or, in rare cases, cardiac events during or after the race. Dehydration and electrolyte imbalances are common, potentially leading to hyponatremia. Additionally, the intense training and race effort can suppress the immune system, making runners more susceptible to illness, and may cause burnout, leading to a complete abandonment of fitness routines. A pre-training medical check-up is crucial to identify personal risk factors, and following a gradual, structured training plan is essential to mitigate these dangers.
