I am on fire!

At least my legs feel like they are burning. Today was the start of week 3 of the 8 week training and, as part of it, I had two-three minute runs I had to complete. This was basically twice as long as any previous segment. My legs were crying for oxygen, but I made it through. As a matter of fact, I finally felt the "runner's high" that I was missing from the last time I did this training. The ironic thing was that I felt it while I was walking, not running, during my cool down. I'm glad I finally had that feeling of euphoria, because the last two weeks of training have felt like torture.
