Butterfly Swims In The Open Water[edit]

"While it takes male Olympic open water swimmers around 1 hour 50 minutes to complete 6.2 miles of swimming in flat-water conditions, it takes a world-class male runner around 1 hour 50 minutes to complete 22.5 miles of running in good conditions (at a 4:53 pace). Therefore, at the highest echelon of the endurance running and swimming world, the world's greatest marathon runners can run 22.5 miles while the world's greatest marathon swimmers can only swim 6.2 miles. In other words, the world-class runners can traverse a distance 3.6 times as far as a world-class swimmer. But while runners run in the open terrain, swimmers can do butterfly, backstroke, breaststroke, and freestyle in the open water.

Butterfly is the stroke in the open water that most intrigues and fascinates us because it remains so extraordinarily difficult to do in the open water. It takes power. It takes guts. It takes strength from the shoulders to the core. It is dramatic as the body is propelled out and forward in the water. Without a doubt, butterfly is the most unforgiving and difficult of all swimming techniques, both in the pool and in the open water." (Quoted from Steven Munatones.)

Brian Suddeth, an open water butterflying aficionado, did some calculations on his fellow butterflyers. Based on his calculations below are some of the speediest distance butterflyers in the world and how fast they are in miles per hour (mph) in various swims around the globe. "At the bottom line, while the FINA official distance for a "Marathon Swim" is 10K, it seems to me that when doing butterfly in the open water, the target distance for a "marathon class" swim is more like 5 kilometers by speed and effort based on the performances of the very best." These swims vary widely in speed, location, and conditions, but are all based on non-wetsuit, FINA legal butterfly, with dolphin kicking only.

The average speed for these 34 butterflyers across these 108 confirmed events is 1.74 mph (2.80 kph). Whether the butterfly was done in a lake or river, bay or ocean, their swims are all very impressive. Very very impressive. (Quoted from Steven Munatones.) Updated 03/01/2020
