Getting rid of mild stiffness

4 days since my race and the passing of my dear cat Smudge.  Decided  its time to  restart my training.  
 A perfect fall day 17 C . Clear blue sky.
Did a slow run along the Waterfront Trail.  Appox 3K.  Purpose of the run was to  get rid of the  mild stiffness i seem to have.

I am entered in the 5K event at the  Scotiabank Toronto  event.  October 20 ( in 3 weeks).
Toronto waterfront marathon. Check out the link. You can probably still enter.
