The weather is dampening my enthusiasm to run.  When I get home from work each night, it's dark.  It has been really cold these past couple of weeks too.  I stayed close to home for last night's run: I did the triple out-and-back at the Royal Victoria Dock.  My right hamstring felt strained from the start and my knees felt cold and stiff.  I kept my strides short and got through the run.  It felt like work.

I think that I just need to keep to the schedule and keep exercising.  These runs will feel better soon, I hope!
