First one done

I just competed in my first tri early this month.  Let me say it was a learning experience.  I knew going in that swimming would be my weakest.  At first I questioned my fitness level despite every minute I snuck into the pool,  tethered thus only counting strokes and not distance.  I would do 120 strokes 3-4 times with a 30 seconds break.  I maintain about a 160 max HR throughout this workout.  I was mainly a roadie until this tri itch I had to scratch.  I am a middle of the pack runner, not really close to breaking any records.  Now I just signed up for my next event in Feb.  The biggest mistake I made on my first event is that I steered way off course and extended the 400m swim.  I thought I was looking up every now and then but to no avail.  I do have a problem with breathing both sides so I will work on this.  I am also swimming with a wetsuit now so this too is different.  Any other advice will be welcomed.  Wish me luck!
