Lay off the sweets

When I arrived at work today there was a large tin of "Heros" perked on the filing cabinet at the end of my row of desks with a note saying help yourself. I've got a sweet tooth and very soon lost count of the number of times I had dipped my hand into the tin before lunchtime. I thought nothing more of it when I went for my lunchtime run.
Today was another one of those simple straight forward plods that are recovery runs, or it was supposed to be a straight forward plod. Just under Half way round I suddenly lacked all energy and if anything felt a little faint. This can be warning sign of a major problem so I double checked my HRM and it said I was only down at 140 so no cardiovascular problems. It was then that I remembered the chocolates I had been eating. Those fatty, refined sugar laden sweets! I must have thrown my blood sugars well out of balance and was paying for it big time. I managed to struggle round the rest of my run but it wasn't a pleasant experience. So the moral of the story is "Lay off the sweets before you go running!"
