Nine months ago, I decided I would like to train and compete in a triathlon. And in a couple weeks, I will stand trembling at the start of my first triathlon: ready to swim 1500 metres, cycle forty kilometres, and end with a ten kilometre run to the finish line. If you’ve been following my journey so far, you’ll know that I am a) an amateur b) the mother of four young children and c) have never attempted anything like this in my entire life.

So maybe you’re wondering: Why a triathlon?
