So, imagine you have a small toy car that you can drive around outside. Now imagine that lots of people around the world have these toy cars too, and they all want to have a big race to see who has the fastest and best toy car.
That's what the IFMAR 1:10 Electric Off-Road World Championship is like. Only instead of toy cars, they use real cars that are the same size as regular remote control cars that people play with outside, but these ones go really fast and are made to drive over dirt, rocks and jumps.
People from all over the world come to this big race, and they spend a lot of time making sure their car is perfect and ready to go. They use special tools to make sure the wheels are just right and the batteries have enough power.
When it's time for the race, each driver has to do their absolute best to drive their car as fast as they can around the track. There are a lot of turns, bumps and jumps on the track, so the drivers have to stay focused and not crash their car.
The driver who finishes the race in the fastest time without crashing wins the championship and gets a special trophy to take home. It's a big deal for the drivers because it shows that they have worked really hard and are the best in the world at driving these special cars.
