What's the problem

I ran 45 minutes Monday.  The best pace I could average and stay in my estimated Zone 2 was 11:40.  I could tell that I was still suffering from respiratory problems.  This run was a 2 (only because I know that I'll have worse runs.)  I also added lunges during my warmup.  Usually lunges have been really difficult for me in the past because of a lack of leg strength.  They were much easier on Monday.  I was a bit sore on Tuesday.

I ran 45 minutes Tuesday.  The best pace I could average and stay in my estimated Zone 2 was even worse than Monday, 12:10.  That's 30 seconds slower.  Again, the problem sees to be respiratory problems.  I am wheezing and rattling when I exhale hard.  I think this run was a 1.5.  I did the lunges again and added leg swings to the warmup.  I think this will be beneficial.  I'm trying to stay away from anaerobic work during my base phase, so general fitness cross-training won't really fit.

I ran 1:07 Wednesday.  My pace was only marginally better, 12:01, as I stayed in Zone 2.  My respiratory problems seemed to be a bit better.  (I need to amend what I wrote about lunges.  I began them on Tuesday, not Monday.  Monday, I just had to get out and run, since I had not run since Wednesday of last week, May 2.  Since I was able to get in 5.5 miles, this run was a 2.5, though I am grateful just to be able to get out there and run.
