I have always been a good breaststroker. I can swim breaststroke for 1-2 miles without stopping with no problem. But I can't swim freestyle for a long distance. I have to stop and take a 30 second break for every 100 yards. Does anyone know what my problem is? Perhaps I don't have the correct technique? I have noticed when I am swimming freestyle, I don't feel as relax as when I am swimming breaststroke. Perhaps just lack of practice? Please help.
By the way, have anyone tried TI swimming? Is it worth it to take the TI workshop? Thank you all for your help.
