I’m working from home this morning, before I travel to London for a meeting, and I thought it would be a good opportunity to get a quick run in first thing. Except, on waking up at 7am, I realised I had tonsils like giant pink golf balls.

I toyed with the idea of still going out - after all, I feel fine within myself - but I’ve made this mistake before when I’ve had a symptom of illness and done exercise anyway. It always seems to accelerate the sickness, so I decided to have an extra half hour in bed, eat my fruit and porridge and make an early start on my emails. I’d be gutted to miss the GNR because of illness, so better to be well, even if I’m not fit.
