The run

I ran for 30 minutes at a very slow pace. I was barely running and I am sure fast walkers could have stayed on the treadmill.  My knee hurt for the first ten minutes and then the pain went away.  My legs were tired but I was not exactly sluggish.  The interesting thing, for me, was that I breathed through my nose the entire time. I wasn't sure if I would faint or what but I was careful and managed it. I am not sure if there was a point to this little challenge though...

Rest now and then back for a short swim workout in an hour or so.
