I've just been for a run. It was bloody hot and hard work, but I feel fantastic now and tbh I enjoyed it a lot even while I was doing it - the lovely sunshine, the park, the ducks and geese the hordes of annoying tourists and so on - lovely.
But trying to persuade myself to go was SOOOO hard - I nearly bottled it. Why do we do this? How does one get to a point where one can go out and exercise without a massive internal debate about it beforehand?
