Finish fifth or better at the Mexico Grand Prix and, no matter what else happens in the race, Lewis Hamilton will win the fourth Drivers' Championship of his career.
It's an incredible feat that would make the Stevenage-born driver the most successful Briton in Formula 1 history, with just four other drivers having ever managed such an achievement.
With just two races to follow, it signals Hamilton's dominance this year as Ferrari's Sebastien Vettel and Daniel Ricciardo were expected to, more heavily, challenge for the title.
Hamilton has won five of the last six races, finishing second to Max Verstappen in Malaysia, which has extended his lead to 66 points over closest rival, Vettel.
And with Mercedes having already wrapped up the Constructors' Championship, the German manufacturer can now focus on allowing their main man to achieve his personal targets.
His teammate, Valtteri Bottas, is well off the pace for the title - despite the car, again, generally proving to be reliable for the Mercedes drivers.
Hamilton dominates fellow title favourites
It was meant to be a season where Fernando Alonso was going to finally get McLaren competing back at the top end of the Constructors' Championship and Vettel aiming for a fifth title.
But Hamilton's dominance and class has, in the second half of the season at least, meant he's left the rest of the chasing pack behind.
And Hamilton's father, Anthony, has admitted his parenting of the 32-year-old had to become particularly strict after the phenomenal offer which was made to Hamilton at McLaren.
McLaren's then team principal, Ron Dennis, made a phenomenal contract offer to Hamilton at just 13 years of age, with the promise of a career in F1.
Hamilton's father reveals strict parenting
“Ron knocked on the door and he basically said to us, ‘You two have won the lottery as long as you keep yourselves clean for the next 10 years’,” Anthony revealed, per The Times.
“For the next 10 years, Lewis had to knuckle down."
Obviously, it was a moment that was set to change the Hamiltons' lives forever, and his father knew a life-changing offer could be in tatters if his adolescent son did not work hard.
“I was hard," Anthony admitted. "He wasn’t allowed to go out with his teenage friends, he couldn’t go partying.
"I told him, ‘Lewis, you have a golden opportunity here and you are not going to waste it. I am sorry, my friend, I will be your dad but I am going to be as hard as I can so that I don’t make a mistake that robs you of your future’.”
And that strict approach at a young age has unquestionably paid off, with Hamilton having become the poster boy of modern day Formula 1.
