By the way, yesterday I swam in one of the roughest sea conditions I had ever experienced.
My brother, who is a triathlon particpant (IM finisher in not a bad time) and no-fear swimmer like me since we were kids, decided not to enter the water and went for a cycling ride. He called me mad.
I swam only for 30 minutes, as the conditions were getting worse and it was plenty of jellyfish, while I could not see anything 30 cms from my eyes.
But I applyed my TI technique (as far as I believe I am doing it correctly, since I just read the book and read the blog and watch videos), and it is wondering how one can cross the water and manage to swim more or less at his/her normal speed while all around you have a mess of brown and sandy water, wind, algae, jellyfish...
