In just 15 days’ time, the final chapter in the story of the 2024 Formula 1 season will be written. A triple header of races - from the bright lights of Las Vegas to the heat of Qatar and Abu Dhabi – will decide the World Championships.

It’s late November, and time for Formula 1 to take up residency in Las Vegas. The sound of engines roaring down the city’s world-famous Strip will soon bring in the crowds. Unlike other races on the calendar, which are organized by local promoters, the Las Vegas Grand Prix is run by F1 itself. So the pressure is on the event’s CEO Renee Wilm to get everything just right. There will be extra focus on this year’s Grand Prix, as Las Vegas is the first race where the 2024 Drivers’ Championship can be decided.

The season has seesawed between Red Bull’s Max Verstappen and McLaren challenger Lando Norris. But it’s Verstappen who can defend his World title, simply by finishing ahead of his British rival in the Grand Prix. Back at base, McLaren are studying the data as they prepare for another crucial event in the U.S.

Aston Martin race engineers Chris Cronin and Andrew Vizard are also doing their homework ahead of the Las Vegas Grand Prix. It’s not just the racing that the teams are preparing for back at base. At every Grand Prix across the season, the team's wine and dine guests and there are some big celebrity names on the Las Vegas guest list. But when night falls for the Las Vegas Grand Prix, and the starting lights go out, all eyes will be on Norris and Verstappen.

The penultimate race of the season for the F1 teams lies 8,000 miles east of Vegas in Qatar. The 2023 race around the Lusail Circuit, which was held earlier in the year, was brutal. Aston Martin driver Lance Stroll and his Performance Coach Henry Howe reveal how they are preparing for the rigours of the desert race.

The 2024 Formula 1 season is also the longest in the sport’s history, with 24 races on the calendar. McLaren driver Oscar Piastri is taking it all in his stride but the Australian does have a unique take on the brain power that is needed in F1.

McLaren are aiming to flex their muscles this weekend because Qatar offers the first chance to clinch the Constructors’ crown. To do that they need to out-score rivals Ferrari by 45 points. The heat is on, in more ways than one, in Qatar.
