I'm not a "group sports" person. I like to do my own thing without having to socialize. Running, biking, even weight-lifting are pretty much solo sports. Put in earphones and go. No interaction required.
You'd think that swimming laps back and forth is also a solo sport. Nope! Swimming is actually a social sport. You need to talk to the person or persons that you're sharing a lane with. You have to look out for them and the people in neighboring lanes. There are no headphones, iPods, or TVs.
There's actually multiple websites all about swimming etiquette! And the park district pool I was at tonight broke most of them. I won't go into details in this post, but I'm seriously considering a short-term membership at a gym with pool and childcare.
Tonight I did 7 laps, which is about the distance in the race. :D 95% was breaststroke. I tried freestyle but I was too self-conscience. At this early stage I think building endurance is more important.
