Butterfly Can Be Brutal

Courtesy of Brian Suddeth, an open water butterflyer.

Butterfly can be brutal, especially in the open water.

Butterfly takes a lot more strength, from the shoulders to the abs, than freestyle. Butterfly takes a lot of power and energy to do in the open water, especially when lifting your head and shoulders out of the water.

Brian Suddeth, an open water butterflyer, calculated the speed of his fellow butterflyers. "At the bottom line, while the FINA official distance for a marathon swim is 10 km, it seems to me that when doing butterfly in the open water, the target distance for a marathon class butterfly swim is more like 5 km by speed and effort based on the performances of the very best."

The average speed for these butterflyers (listed by the fastest kph) across these 62 events in lakes, rivers, oceans and bays is 1.74 mph (2.79 kph).

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...
