Is It Humid Out Here or Is It Just Me?

Went out this morning for my run since there was a possibility of rain later in the day, and as I expected it was plenty humid. I ran my 6 miles, and it went way better than Saturday's run. Miles 2-4 included a pickup, although I walked briefly at the turnaround. My pace got down to the 9:00 range, and a few times a little under that. For the most part it hovered between 9:15-9:35, though. I'm trying to get a little speedwork in before the 5k, but I'm also thinking the conditions might be this humid then, too. If that's the case my hopes for a fast race will go right out the window.
