After my abysmal lack of performance at last Saturday's Parkrun I've decided to fight the despondency and gone back to week 9 running today. I ran on empty, having had a pasta meal last night, and felt much better. I felt comfortable all the way and finished the run. It is obvious that the timing of your food intake is important.
And I was nice to a lady dog walker who put her 3 large mutts back on their leads as I approached. Thanked her and told her I appreciated it - which I really did!
