13 Today.

I ran home today from work.  I ran 5 miles up the Charles, then turned north through Watertown, Belmont and into fresh pond.  That was about 2.5 miles, then did 3.5 miles around the pond.  The final 2 miles was the tough 2 miles up into arlington.  Pacing was awful, but I don't care: 8:08, 7:46, 7:47, 7:59, 8:11, 8:18, 8:26, 8:34, 8:37, 9:31, 8:56, 8:59, 9:40.  Overall was about 8:30.  Legs felt pretty good, but they are nice and sore.  It's funny, 13 felt hard, but I only have 4 runs that are longer in length.
