It was utterly ridiculously hot. The sort of hot that would have cause Michael Jackson's face to run, and that the chocolate stash in my pannier didn't stand a chance against. Anyway, it's no secret that I'm not a morning person and I don't do well in the heat, and after several hours of it I was suffering a mysterious ankle pain, symptoms of something on the hyponatraemia to migraine spectrum, and a total sense of humor failure. As such I can only apologise to those I was snappy, incoherent or excessively sarcastic at. I have since stuck my head in some cold water, restored my electrolyte balance with some Proper Food, and spent an hour or so lying in the dark with a book - and feel much better for it.
No idea about the ankle, will see how it goes. I'm used to Knees.
