“Run like hell and get the agony over with.” -Clarence DeMar
DeMar had an incredible string of Boston Marathon finishes. Diagnosed with a heart murmur and following advice by doctors who examined him, DeMar took several years away from marathoning. Eventually, he must have ignored their advise and resumed racing, and you can see the results.

According to The Athlete Within by Dr. David Costill, autopsy results on DeMar revealed "a significantly enlarged heart with relatively clean coronary arteries." Left ventricular wall thickness- 18 mm (10-12 mm is normal)
Right ventricular wall thickness- 8 mm (3-4 mm is normal)
Diameter of coronary arteries (2-3 x normal size)
