It's that thing that stops you moving off the sofa you've collapsed into post work combined with a full stomach and early evening fatigue kicking in. All the plans made previously are looking like they are going to flutter out the window as you change into a couch potato.
No, no, no this is not going to happen; I am worth more than this. I can make plans and fulfill them even combating the low level drowsiness caused by food and a good old sit down.
So for the people at work today who I told I was going on a run this evening...yes I am, I will, I will,I will.
Some life admin whilst tea settles (I can't run on an empty stomach) then time to get those running shoes on so I can run into the sunset!!!
