I think I made a little mistake. In the effort to complete a mini-goal of being able to run for 30 minutes straight, I went running this afternoon at the SRC. After my 1.5 mile run, I kept walking for the rest of the time, then did some light upper-body weights and stretching. And now, my hammies are screaming, "What the hell did you do to us?!" and threatening to go on strike. What more can I give you, hamstrings?
