BBC Sport chief sports writer Tom Fordyce helped the Brownlees write their autobiography in the wake of their gold-bronze success at London 2012.
Who better to talk through them turning the Rio race into a family affair? Nobody that's who.
"There is so much that is ordinary about the Brownlee brothers. Breakfast at Alistair's is large bowls of own-brand discount supermarket cereal. Jonny's favourite tea is fish and chips, eaten Yorkshire style with a side-plate of white bread," he writes in his review of the brothers' latest success.
"Jonny likes to relax by watching Leeds United at Elland Road or Leeds Rhinos at Headingley. Alistair, sufferer supreme in his sport, likes to watch rom-coms. When he went out to buy a new car, he promised to buy an Aston Martin and came back with a Volvo."
