The Nike+ was pretty spot on this morning. 4.01 exactly for the 4 mile loop (officially it's 4.04).

Not a bad run. Although, there's this one section where I just don't get why it's so bad. I come to the top of a hill and get to head down a long gentle slope. You can barely tell it's going down, but it is. For some reason, every time I get to that section my legs feel like lead (the hill prior is not steep, so I can't attribute it to that). It's a really hard slog. It's around the 2.8mile mark.
