Here’s How Mercedes-AMG F1 Drivers Prepare for Sepang

Few races test the physical fitness of the modern-day Formula One driver quite like the Malaysian Grand Prix. The 5.543 km Sepang International Circuit plays host to one of the most gruelling events on the calendar, with ambient temperatures averaging more than 30°C and humidity typically around 70%.

In Sepang, cockpit temperatures frequently hit numbers approaching 50°C. And for the driver – cocooned in a hot, stuffy, confined space, tightly packaged themselves in layers of fireproof nomex and fighting extreme G-Forces on their body – it’s a serious test of physical fitness.

For this reason, many drivers tend to arrive in Malaysia as early as possible in an effort to acclimatise to the heat and the humidity.

This is one of the races on the calendar where all the physical training drivers put themselves through during the off-season – and then maintain over the course of the year – really shows.

During a typical Malaysian Grand Prix, a driver’s heart rate can reach as high as 170 bpm, burning up to 1,500 calories and losing around three litres of body fluid in sweat. Over a 90 minute Grand Prix, that’s roughly 5% of their overall body weight, making hydration management crucial if they are to see off the threat of fatigue.

Many F1 drivers now wear a cooling vest pre-race while waiting on the grid to keep the harsh heat off them.

During the race itself, drivers rely on their in-car drinks bottle – filled with a mixture of sports drink and electrolytes – to replace lost fluids from sweat. It’s a battle against fatigue. And if there’s any race you don’t want your drinks bottle to fail, it’s Malaysia.

Post-race, the immediate focus for the driver is on cooling their body and rehydrating. Those enticing bottles of water don’t last long in the cool-down room before the drivers hit the podium for the slightly sweeter taste of champagne!

And it’s not just the drivers that have to contend with the sweaty conditions. Working temperatures in the garage exceed 40°C in Sepang, with humidity often rising above 90%. It’s a double whammy, meaning increased sweat and a greater chance of dehydration.

The team – especially the mechanics, who have to suit up during pit stops – are constantly reminded to keep up their fluid levels, or risk dehydration. Long-haul flights, too, have a dehydrating effect, owing to the recirculated air. So, the battle for the team starts before they even hit the track, on the flight over to Kuala Lumpur.

For the Silver Arrows, Hintsa Performance are on hand to ensure the team are well educated on staying hydrated, so that everyone – from the drivers and management to the mechanics and garage technicians – arrive in the right state to go racing.

From the balance between staying active and relaxing at the right times outside of work to managing water consumption and hydration sachets during busy periods and even levels of exposure to bright light, there are a plenty of tricks of the trade to keep everyone on their feet. No matter where you turn in Formula One, performance optimisation isn’t far away.

Handling the heat in Malaysia isn’t easy. But the men and women soldiering through the sweat will be doing all they can to stay cool as the title battle hots up in Sepang…
