What's A Marathon Swim?
The answer depends who you talk to. But for much of the open water swimming world, the accepted distance of a marathon swim is 10 kilometers. Why?
10 km is the distance that is defined by the International Olympic Committee, FINA and the International Marathon Swimming Hall of Fame as a marathon swim.
The roots of this determination derive from the fact that it takes world-class swimmers about 2 hours to swim a 10 km swim in almost all venues and conditions - which is nearly the same time it takes world-class marathon runners to run a 42 km marathon.*
The governing bodies and association wanted to make the duration of the marathon swim performed by world-class athletes roughly equivalent to the duration achieved by world-class runners.
Some traditionalists believe marathon swimming distances do not begin until a minimum of 15 km or 25 km or 20 miles and use the term ultra marathon swim to define swims of longer distances. The distance of 25 km (15.5 miles) is the often used minimum distance of an ultra marathon swim. This is similar to the running community that defines an ultramarathon (also called ultra distance) as any running event longer than the traditional running marathon length of 42.195K (26.2188 miles).
* The world's top male swimmers can complete a flat-water course in about 1 hour 52 minutes and the world's top female swimmers can complete the same course in about 2 hours. Their running counterparts on land complete marathon runs between 2:05 - 2:10 for men and 2:20 - 2:30 for women.

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...
