Refueling required

Early swim this morning and it was a tough session. 500m warm up, 200m of drills, 4 x 50m fast / 50m easy, 16 x 100m (targeted time) and 100m warm down.  My times slipped in the last 6 100's and I knew I was tiring.  Once I had finished work and done some Dad taxi duties I was exhausted and was considering missing out my scheduled run.  But at times like this you have to dig deep so I refuelled and my energy returned.
However the run was horrible.  There was a strong wind and when I got into the countryside it was pitch black which would have been fine but there was a heavy fog.  My head torch bounced back off the fog and I could only see 2 yards in front of me.  I couldn't see the side of the road and was worried about pot holes appearing from the dark.  For safety reasons I changed my route but struggled in the dark and the fog for a good 15 minutes.  I finished slightly behind target but was pleased I didn't succumb to the couch and then have to live with the guilt!  When you're tired, take fuel on board and get out there - you're a long time dead so live every moment!
