Channel Fat Is Bioprene But Certainly Not Neoprene

Out in the open water - especially while swimming in the middle of the Cook Strait, Molokai Channel, Catalina Channel, Rottnest Channel, Farallon Islands or anywhere in Cape Town, swimmers sometimes refer to sharks as 'fish' or 'The Man in the Gray Suit'.

There are other creative terms used around lakes, lochs and docks in the channel swimming community including channel fat and bioprene - referring to the oft-used methodology of gaining weight in order to acclimatize to cold water marathon swims.

Bioprene (noun): An abundant layer of hypodermis or subcutaneous tissue, that is mainly used for fat storage and a natural means to help tolerate cold water by marathon swimmers.

The channel swimmer ate a box of donuts every morning in order to add to his layer of bioprene. [Origin: bio + neoprene or polychloroprene, a synthetic rubber that is used for wetsuits. Neoprene is the DuPont trade name for its brand of polychloroprene].*

Channel fat or extra weight, largely in the form of abundant layer of hypodermis, that is purposefully put on and carried by channel swimmers and marathon swimmers as a natural means to help tolerate cold water during channel or marathon swims.

Photo shows marathon swimmer John van Wisse who is normally svelte, but who bulked up with some additional bioprene for his two-way crossing of the English Channel.

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...
