The Relative Consistency Of Swimming Around The Clock

It was all difficult fun: 24 straight hours swimming in Aquatic Park in San Francisco, California as a relay. The swimmers switched on and off with their teammates swimming, napping, laughing, and eating.

While Madhuri Yechuri of India completed all her hour-long legs during the 24 Hour Relay in San Francisco swimming butterfly, both day and night during the 2016 event, Bruckner Chase of Ocean City Swim Club in New Jersey swam freestyle throughout the 2014 event with a Suunto GPS watch on.

We wondered how far the swimmers each swam during this 24-hour marathon relay and how their distances varied on each leg.

Chase gave us insight on his own distances swum over his 7 legs during the 2014 event:

Leg 1 at 8:57 am, he swam 1,300 yards in 14 minutes 29 seconds or 1:11.4 per 100 yards
Leg 2 at 11:28 am, he swam 1,300 yards in 14 minutes 35 seconds or 1:12.1 per 100 yards
Leg 3 at 1:47 pm, he swam 1,300 yards in 14 minutes 18 seconds or 1:11.0 per 100 yards
Leg 4 at 5:25 pm, he swam 1,300 yards in 13 minutes 55 seconds or 1:07.0 per 100 yards
Leg 5 at 9:36 am, he swam 1,300 yards in 15 minutes 15 seconds or 1:22.5 per 100 yards
Leg 6 at 2:26 am, he swam 1,600 yards in 19 minutes 19 seconds or 1:20.7 per 100 yards
Leg 7 at 6:49 am, he swam 2,600 yards in 29 minutes 10 seconds or 1:12.1 per 100 yards

Despite the rains, winds, and water and air temperatures dipping down into the high 40sºF (sub-10ºC), Chase's pacing was remarkably even throughout the day and night [see video below] - something that is usually the case with many marathon and channel swimmers, all things being equal.

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 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...

The trends are very clear.
The tide is rising for open water swimming.
