Just wait for when the Danes hear of this Discipline!
Oh and sara, I can really recomment try the 16x50m

It's fun and a quick way of training, especially if you got a good coach giving you the countdown and suggestions of improvements each time you come up. It help greatly to improve CO2 tolerance too.
What's the 16x50m world record for women?
For men it's Michael Asp's with a time of 11'16"
BTW, 108,2KM is not easy I think. In 24hours there are 86400 seconds, so on average people have to swim 1,2523 m/seconds or les than 40 seconds for a 50m lane, for 24 hours!
Perhabs I glanced over something vital?
