What is it about Fridays?

Today's run (street): 2.25

It has been a busy week and I thought "TGIF" when I went out for this morning's run. However, within five minutes, I knew that I was in for a bad Friday run for the second week in a row. I'm guessing that I'm fatigued from three days of intense discussions, presentations and other stressful factors. I don't care that much about having a bad run, but I do like to know why I ran badly.

I've switched over from my Hattori's to my Saucony Mirages since the Oyster Bay 5K in hopes of eliminating the slight, but nagging, pain I get between my right heel and Achilles. I figured that the stability post on the Mirage might help that somewhat. When I went out today, the pain was there and it was fairly pronounced. As usual, the pain subsided once I'd traveled about a mile.

It's hard to understand exactly what made today's run bad. I had no obvious issues (besides the heel pain), but I couldn't generate much speed. I cut my distance short because I wanted to use the extra few minutes to rest before my shower. I really need to be on my game this weekend and get some base miles in since I haven't done too many 5+ mile runs lately and I have a fast 6.2 scheduled on November 13. I'm hoping that my Friday curse won't extend to Saturday.
