Swimming is probably one of my favorite too. But I don't compete too much in it. I am not sure I can swim very well. I just enjoy emersing myself in water. The only competition i think I can do really well is holding my breath under water for a long time.. . I just calm myself under water back then and forgot I even exist... Or I go into deep hibernation/meditation/imagination to distract myself from the danger of being under water without breathing. Works great for me. Not recommended to any kind of person though.
