I am a TERRIBLE runner!  I lack the endurance needed
I am, too.  But there are "couch to 4k" programs out there for people like us.
When I was young I considered joining the military, but it is often a big component of the training.  I wish I knew about the couch to 4k program then!
I haven't tried running recently.  Have you?
No, I know I should because it is such a great part of physical exercise.  Some people even like it for recreation.  Which sounds terrible to me.
