It can only mean one thing when, on opening the front door to the postman in your dressing gown, he hands you a black plastic package with a high-vis Rapha label in the top right corner.
What does it mean? It means it's time for awesome, that's what.
Inside this package of hope and happiness should be a Long Sleeve Brevet Jersey (grey), a matching set of merino socks and a Rapha bidon. More on all of these items later.
That is all.
