First run in 10 days after cat sitting and insomnia - my knee was starting to twinge, weirdly running is the best thing for my knee pain, and it's improved now, but boy it felt warm and I clearly haven't recovered from lack of sleep yet as I really struggled, even had to use my emergency cash to stop in a shop to get a drink!!! Got an hour to recover then couple of client meetings. Hope I don't fall asleep!!
