2 1/2 Miles...A Slow Start

This morning I got up early and did a run. The first one in quite a
while. I went slow. I did about 2.5 miles before I started walking
the rest. My knee was bugging me. My goal is to build up slowly in
order to prevent any injuries. I've tried building up quickly before,
and I paid for it. It was dark and foggy during my run. Nice and
cool for a change. Wore my Mizuno Wave Rider 7s.
