The Paradox Of Exercise
According to the article in Peak Performance, "...any athlete who participates in a strenuous test of endurance lasting about three hours or more has an increased chance of dying during - and for 24 hours following - the exertion, even when the athlete's chance of a death-door knock is compared with the risk incurred by a cigarette-smoking, sedentary layabout who spends the same 24 hours drinking beer and watching TV..."
The articles stated that "...if you run marathons or participate in other forms of exercise which last for three hours or more, that's your approximate risk of suffering an acute heart attack or sudden cardiac death during - or within 24 hours of - your effort. For every 50,000 athletes, one will be stricken during such prolonged activity."
At the same time, research also indicates that well-trained endurance athletes have about 40% of their sedentary counterpart's risk of dying from a cardiac problem on a typical day. Peak Performance concluded that "...heart attack risks are greater for athletes who compete in endurance sports...the paradox of exercise is that it increases your risk of dying at the same time that it reduces it."
But if one does one marathon event per year, there seems to be an advantage of doing an endurance event. That is, if we reduce the chances of dying 364 days per year while increasing the odds of suffering cardiac arrest 1 day per year, then that tradeoff seems like a good bet.
And those odds do not incorporate or calculate the immense amount of joy, camaraderie, challenge and allure of leading a unique and exciting lifestyle with like-minded open water swimmers in the natural environment.

The Other Shore
The Other Shore follows world record holder and legendary swimmer Diana Nyad as she comes out of a thirty-year retirement to re-attempt an elusive dream: swimming 103 miles non-stop from Cuba to Florida without the use of a shark cage. Her past and present collide in her obsession with a feat that nobody has ever accomplished. At the edge of The Devil’s Triangle, tropical storms, sharks, venomous jellyfish, and one of the strongest ocean currents in the world, all prove to be life-threatening realities. Timothy Wheeler’s documentary brings Diana Nyad’s extraordinary adventure to life as Diana sets out to prove that will and determination are all you need to make the unimaginable possible.
2014 Open Water Swimming Almanac
An Almanac for Open Water SwimmingAn almanac is essentially a body of knowledge which is so complete that it enables people in different fields to make predictions about the future of their respective industries.
This, for example, was the purpose of the traditional farmers almanacs. It enabled farmers to determine as accurately as possible which crops to plant for the greatest harvests in a given year.
But the farmers almanac was just one example among many.
There are, of course, many different kinds of almanacs.
In fact, there is even one for open water swimming...
