Saturday walk/run gave me a headache

So my running guru boss told me I couldn't take the weekend off and she made sense, I need this to be a new lifestyle not just something I do to skip out of work for half an hour a day ;-)

I've done my usual route but with my little running buddy today. It was really hot and I don't think I should have gone out so soon after breakfast as I felt really sluggish.  Lesson learnt for next week.

Still not a bad time though considering...
