Grinding to a halt

Motivation is low at the moment and my running miles have reduced a lot which is probably down to the fact I am working 6 day weeks and part of the evenings as well.

When I have gone out for a run my performance is pretty good but I find myself slacking off not because I am not able to do it, it is just I can't be bothered a lot of the time.

Take last weekend, I was working in London on the Saturday at the university and was all kitted up to run back home, come 4.30pm I looked out of the window and decided then and there that I wasn't going to run and took the train home then opted out of a run on the Sunday as I was just too tired even to contemplate getting up early.

Today I am again kitted up and just have to drag myself out of the lab to get to the Thames Path and home.

I am not sure what my problem is (apart from the obvious tiredness) but emotionally I am trying to fight a downturn in my mood.
