overexercising - death

I don't think that condition is related to physical activity rather the following:

Introduction

Left ventricular hypertrophy, or LVH, is defined by the Mayo Clinic as an “enlargement (hypertrophy) of the muscle tissue that makes up the wall of [the] heart's main pumping chamber (left ventricle).” The left ventricle's muscle tissue increases as a response

Changes in the heart from left ventricular hypertrophy (Georgia Department of Community Health)

to the heart needing to pump more blood. However, the Mayo Clinic states that over time “the walls of the

chamber grow thicker, lose elasticity and eventually may fail to pump with as much force as a healthy heart.” As a result, the patient has an increased risk of having a heart attack, arrhythmia or sudden cardiac arrest. The patient's quality of life is also affected by left ventricular hypertrophy. If the cause of left ventricular hypertrophy is not treated, the patient's risk of death increases.
Causes

The Mayo Clinic notes that the causes of left ventricular hypertrophy force the heart to pump more blood; examples include hypertension, aortic valve stenosis, aortic valve regurgitation, dilated cardiomypathy and a heart attack. Each of these causes forces the muscles to work harder and cause damage to the heart. Hypertension, or high blood pressure, is defined as a systolic pressure of 140 mm Hg or above and diastolic pressure of 90 mm Hg or above. Aortic valve stenosis is a condition where the aortic valve is narrowed, preventing normal blood flow from the left ventricle. Aortic valve regurgitation involves a dysfunction of the heart valve between the aorta and left ventricle; this results in blood flowing back into the left ventricle. Dilated cardiomypathy is another heart condition where the left ventricle is enlarged; due to the larger size of the ventricle, more blood accumulates, which forces the left ventricle to work harder. Patients who have a heart attack have scarring of the muscle tissue, which results in the other muscles to compensate.

Oh okay fair dooz. I just thought I remembered reading something about it..

actually after just have gone back to the article the symtoms can be recognoised from physical activity so well done from noticing

Weirdly, I've seen more runners in the snow than I did in the summer. Crazy days!!
