Men vs. Women In The Open Water

Sex differences between the world’s best athletes in most events have remained relatively stable at approximately 8 to 12%,” explained Øyvind Sandbakk, Ph.D., managing director of the Centre for Elite Sports Research at the Norwegian University of Science and Technology, to Healthline.

The exceptions are events in which upper-body power is a major contributor, where this difference is more than 12%, and ultra-endurance swimming, where the gap is now less than 5%."

Although women generally do not outperform men in endurance events, open-water ultra-endurance swimming offers an exception,” Dr. Sandbakk said.

In the 32-kilometer Catalina Channel Swim and 46-kilometer Manhattan Island Marathon Swim, the fastest women ever were faster than the best-performing men. Although these two races are currently the exceptions where women outperform men, the sex differences in open-water swimming are indeed smaller than in other sports.

"While the data points to the accuracy of Dr. Sandbakk's statements and research in the Catalina Channel swims and the Manhattan Island Marathon Swim, I think there are some additional surprising conclusions and generally unrecognized information about the sport," added Steven Munatones of the World Open Water Swimming Association.

"Firstly, the record for the Manhattan Island Marathon Swim - like the Catalina Channel and the English Channel - has been held at separate times by both male and female swimmers throughout its history. At the time of Dr. Sandbakk's research, Shelley Taylor-Smith held the record for swimming around Manhattan, but it is currently held by Oliver Wilkinson.

Secondly, there is an important differences among swimmers at the elite levels comparing the Catalina Channel and the English Channel. When Penny Dean set the existing record (back in 1976), she was young and nearing the pinnacle of her career. But there has not been a top professional male marathon swimmer attempt the Catalina Channel since Chad Hundeby crossed in 1993.

In contrast, many top professional men have made attempts at the English Channel and the men dominate history's fastest times.*

But dig deeper and the average time for successful female English Channel swimmers is faster than the average time of the successful male English Channel swimmers since 1875 (note: all DNF's were not counted). So Dr. Sandbakk's conclusion stands not only true at least in the English Channel, but also across the test of time in the most renowned marathon swim in the world

2014 Open Water Swimming Almanac



An Almanac for Open Water Swimming

An 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...
