"Not moving as freely as is usual or desirable," that sounds like me after my long runs. Should I be this stiff? Heck, I don't know but I know that each long run I run a little further and that means I am getting closer to my goal.
Admittedly I have been slack lately with colds, flus, blizzards, etc. Any excuse to not get out there sometimes it feels like.
After this weekends 14 mile run though I know I have to stop missing runs. I want to get my speed workouts in and I need that medium run mid-week to try to reduce the amount of stiffness coming from my long run on the weekend.
Stretching certainly helps with the stiffness and is key to not getting too tight as the miles add up. I'll be doing more tonight (already have in some stretches this morning).
On another note, I hit the 250 km mark on the way to my 1000 km in 2008 goal. And I am only 2.5 months in. If I was to keep up this level of running I would hit 1200 km in 2008. Maybe that will be the stretch goal ;-)
