Michael Phelps is a beast! At Rio he achieved his 20th and 21st gold medals!
Swimming is normal for me.
Which stroke is your favorite? Breaststroke is actually the oldest stroke, and is considered by some to be the hardest.
Freestyle is my favorite stroke.  
Do you do any competitive swimming? Freestyle is a super fast stroke! Lots of triathletes use it.
Yes, competitive swimming can be done both solo or on a team. I prefer a team rather than solo.
That sounds fun! How many people are on your team?
Four swimmers including myself.
Have you considered doing a triathlon? Lots of triathletes aren't experienced swimmers, so you'd have a competitive edge!
If you know how to swim, It's probably easier than you think. After you've done a few races the experience changes.
