I love to swim long distances.
Swimming is a great activity and very popular.
Also great exercise.  Do you know that in certain fields of the military they teach about swimming more efficently?
I did not know that. Have you ever competed in a swimming relay?
Yes in high school.  I am an excellent swimmer.  Once swam the length of a 4 mile bridge.  What is your swimming experience?
I am definitely no Michael Phelps. I don't like swimming at all.
