45 minutes

So, my PT wanted me to try running for 45 minutes instead of 30, which I did today.  It seemed about the same: a bit sore when I started out, fine for most of the run, a little sore afterward, but nothing major.  I AM a bit discourage, though, since it doesn't really seem to be getting any better...  Is the PT helping at all?  Will I just have to learn to get used to this level of discomfort until after my Ironman?  Hmm...
