This weekend it happened again.

In 16 minutes 3 people lost their lives at the Detroit marathon.

Thirty-six-year-old Daniel Langdon collapsed at about 9:02 am on Sunday between the 11 and 12-mile markers and 65-year-old Rick Brown collapsed at 9:17 am, near where Langdon went down. One minute later, 26-year-old Jon Fenlon collapsed just after finishing the 13.1-mile half-marathon.1

In spite of what all the so-called fitness gurus tell you on TV there is plenty of evidence that marathon running accelerates heart disease and on occasion can trigger sudden cardiac arrest.

Adding repeated “cardio” to our busy days and pushing for greater endurance produces the opposite result of what we need in the modern world.

Routinely forcing your body to perform the same continuous cardiovascular challenge, by repeating the same movement, at the same rate, thousands of times over, without variation, without rest, is unnatural.

Our ancient ancestors never ran for long distances without rest. Maybe it happened rarely but never routinely. It doesn’t happen in the animal kingdom either.

Long-distance running shrinks your lungs and downsizes your heart’s output. Nature designed your body to adapt to whatever environment it encounters. If you ask it to run long distances repeatedly and routinely, it will adapt to meet the challenge more effectively. When you run long distances like in a marathon you’re actually training your heart to get weaker.

Why does this happen?

Your body downsizes your heart and lungs to enable a long-distance run. A smaller output will take you long distances more efficiently in the same way an economy car with a small engine gets you better gas mileage.

But that’s not what your heart was designed for… it’s built more like a Ferrari: powerful bursts over short distances with plenty of reserve power when you need it.

Results from Boston area hospitals reveal the risks and damaging effects experienced by dozens of marathon runners they’ve studied over the last ten years.
