Lazy workout

I must be the laziest runner ever.  I was disappointed with my 5K time over the weekend and I know that speed work is the answer to a better time.  But I just don't want to work that hard.  So instead, I run 5.5 miles at 11:00 minutes miles because I know that I can keep that pace up forever.  Now I'm disappointed in my workout because when I finished, my recovery time was about 3 minutes.  I realized that I hardly even got winded.  I'm the world's laziest runner.
