PREVIOUS ANSWER #2 ...I regularly swam 2 laps underwater in an Olympic size pool (total 108 yards) -
MY ANSWER:
My total distance on one breath underwater is 110 Meters or 360.89' that's 2.25 lengths of the Olympic pool.
I can also hold my breath exhaled (no air in my lungs) and sit on the bottom of the pool for about 60 seconds. One time I got the life guard off of his stand and almost had him in the water and everyone else was making quite a fuss when I came to the surface unharmed. :)
There are two ways at looking at this record but they were both set by the same person so either way Slovenian Martin Strel made the world's longest swim.
In 2001 Martin Strel swam 504 KM or 312 miles down the Danube river. He covered the distance in 84 hours 10 minutes of nonstop swimming.
In 2002 Martin Strel from Slovenia swam the Mississippi river, a total of 3,885 km or 2,360 miles. He covered the distance in 68 days.
Although there is no distance beyond 1,500m in the swimming pool, there are longer distances in open water swimming competitions where both men and women compete in races from 800m up to 80km+.
The 10km open water swim is now an Olympic event being included in the Beijing Olympics in 2008 for the first time, with the ggold medalist being Maarten van der Weijden from the Netherlands in 1hr 51minutes 51seconds.
The recent World Swimming Championnships in Rome (2009) also included open water swimming, with the three distances being competed being 5km, 10km and 25km. The mens 10km open water was won by Thomas Lurz of Germany in 1hr 52minutes, less than 1.5 seconds ahead of the second placed swimmer!
Since the weather and water conditions can affect the time of the race dramatically FINA do not hold World Records for open water swimming however Maarten van der Weijden's performance is the Olympics was the first 10km swim under 1hr 52minutes

(1 meter = 3.2808399 feet)
