Okay, so today I want to talk about a question that bugs me for a long time – why do F1 drivers get weighed before and after a race? I mean, I get it, they’re like, the top athletes in the world, but this whole weighing thing seemed a bit much, you know?
So, I started digging. First, I hit up some F1 forums. Let me tell you, those places are a goldmine of info. People were throwing around all sorts of ideas, from checking if drivers were losing too much weight to making sure the cars met some weight rules. I read through tons of posts, trying to make sense of it all.

Then, I moved on to some articles. Some were pretty technical, talking about “ballast” and “FIA regulations.” I had to read those a couple of times to get what they were saying. Some of the articles mentioned that in some hot races, drivers can lose up to 3 kg of weight! It was kind of mind-blowing.
Here is what I have found in general.
First, about the health reason:
- The drivers seat in those F1 cars under the sun, those cockpits can get hotter than an oven, sometimes over 50 degrees Celsius! And when they are driving for almost 2 hours, they’re sweating like crazy. So, the docs need to know how much weight they’re losing to make sure they’re not getting dehydrated.
Then, there’s this whole technical side to it:
- Turns out, there’s a minimum weight rule in F1 for both the car and the driver.
- If a driver’s too light, they add extra weight to the car. And after the race, they check again to make sure everyone’s still within the limits.
- They also do this to make sure that lighter drivers don’t give teams an unfair advantage.
After spending hours on this, it finally clicked. It is not just about the drivers’ health, which is super important, but it’s also about keeping the competition fair. They’ve got rules to make sure no one’s getting an edge just ’cause they’re lighter. They weigh the drivers before the race to get a baseline and to figure out the average weight loss during a race, which helps them tweak their training. Then, after the race, they weigh them again to make sure they’re still above the minimum weight and to double-check that the teams followed the rules about adding weight to the car.

And there you have it. That’s why they weigh F1 drivers before and after a race. It’s a mix of looking out for their health and making sure the race is fair and square. Who knew there was so much to it?
