I ran along the water to the "two cement blocks" on the beach trail, very near the Townsite sewer. Nice description there I know, but it's better than it sounds. Trust me. Anyway, I ran very easy there, which is probably 4.5 -5k away, and then on the return, would run 4 X 5:00 with 1:00 complete rest. I ended up running (3 X 5:00) + (1 X 3:53) until I got to the end of the seawalk. It just so happened that after my third repeat I was standing next to my 1k mark on the seawalk, and couldn't resist timing the last repeat, as it was exactly 1k.
A decent workout in the warmth of the September sun.
