I was to do an easy 4 miles this morning. I woke up late since I’m on vacation. I only realized that I was supposed to run at about 9 AM. Also after yesterday’s hill workout I was stiff. So this morning only 12 hours later I ran, but I felt so sluggish. I just couldn’t catch my breath. The 4 miles seemed to take so long to complete. I forced myself to get it done. It was a hard 4 miles.
