Thanks very much, everyone!
RRR - Love the Pauli stuff and I bet you did not think that I caught the Seinfeld reference. Excellent!
Stone - Your comments are appreciated. I did not think I could run in pain for eight miles and so I learned a lot about myself today.
Allen - You are exactly right—went out conservatively with 6:46 and 6:31 in the first two miles, and then BAM was in nice cruise mode for a long while, clicking off low 6:20s and sub-6:20 miles (6:20 is PR pace). It really came down to enduring the last eight miles, alone.
