I had always presumed early morning exercisers were chipper creatures, all bounce and bonhomie. I pictured them in their neon lycra peppering their 6am conversations with jaunty clichés such as ‘Life is short!’ or ‘I’ll sleep when I’m dead!’

For years I’ve envied early-risers their kinetic superiority, their alertness, their chirpy sociability. Waking up should be a laborious, cantankerous process – and if I’m attempting it, I should be avoided until after breakfast.

Now, I am an early-morning exerciser – by default. At dawn, I disentangle myself from the small sweaty octopus who has crept into our bed and commandeered my pillow. Three-year-old daughter has been unusually generous in allowing me a handkerchief of bare sheet. She and her father are rolled up in the doona like pigs in a blanket.
