Getting out again

After another rubbish night and working the morning I wasn’t sure I had enough energy but luckily I was dragged out to the canal by a couple of other members of the race squad. I actually feel more energetic with 4 miles under my belt! I can’t fathom why I did a good time - there have been days when I worked much harder for much worse results. I doubt my technique varies that much. Maybe someone had opened the locks and there was actually some flow on the canal?
