The IRONMAN, Marathon de Sables, matathons and triathlons are long distance and long duration events, these take the human body and the concept of fitness to a whole new level. So they also entail extra precautions during training and competitions.
When training for any long duration endurance event special attention should be paid to the cardiovascular system, esp the heart. The endurance athlete must let his heart recover just as he lets his skeletal muscles recover.
We must not forget that the heart is also a muscle and can develop complications if overworked.
Just as our muscles get sore after the event, the heart also experiences stress.
A common cause is known as Heart Muscle Hypertrophy (hypertrophic cardiomyopathy), a disease in which the heart muscle becomes abnormally thick. this, combined with the stress and epinephrine that come with strenuous physical activity, can lead to abnormal heart rhythms and sudden death.
