In 2024, there were the Olympic Games were held in France.

Your original text was not grammatically incorrect, but it would flow more smoothly like this.

I remember being always watching the TV in order to attend totrack all the gold medals and to miss nothing.

I'm not sure exactly what you mean by attend to. Better verbs might be to track (follow closely, like if you are tallying the rankings), or witness (see firsthand, watch every gold medal match).

By the way, this year, we performed well and we figurranked among the best countries (with the number of gold medals).

Second comma isn't necessary.
Performed well, or excelled - by itself "performed" only indicates that you were there.
Ranked is a better word here than figured.
Even more fluid would be to say "we ranked among the countries with the most gold medals."

Hands down, the big man of these Olympic Games is Léon Marchand, the fFrench swimmer with his 4 gold medals.

I remember his first one, when he clearly dominated all his opponents and won by more than 50 metters (that's huge).

I was stcreaming in front of my TV to support him, but he deffineitely didn't need help from anybody.

Another incredible sportsman who performedat these Olympics was Teddy Rinner.

Again, I think performed is too soft a word for what you want to say here. You can just say "he was there" (like I've said above), since you're about to go into more details. Or you could say something like "who brought home Gold medals"

Incredible at judo, he already had won 2 oOlympic titles.

But this year was special for him, in front of his own publiccountrymen, he didn't have theany choice but to win.

The last part of the sentence is a bit of an English "set phrase." I know it sounds awkward!

And he madedid it twice!

One aloneAnd he did it twice - one as a solo competitor and the other with the French team.

This by itself isn't a complete sentence; I'd combine it with the previous sentence.
"One alone" just reads a bit odd to the native English ear. You could say "once alone" - but I think adding a bit more context as shows above would be better.

It was a piece of cake for the legend he wais.

Even though the final was in the past, he is still a legend in the present.

However, the second final who opposich paired the French team to the Japanese team was way more difficult.

They were losing by 3 1to 1. (tThe game finished when the first team reached 4).)

You really have two complete sentences here, so I would adjust the periods as shown.

But the French team were strong mentally, and they managed to come back to 3 to 3.

Or even better, "they managed to come back to tie the score 3 to 3." That also avoids having the short word "to" twice so close together.

The final fight was choosen with a random spin of the wheel.

And it bumped into Tthe category "more than 100 kg" which meant Teddy Rinner willould fight again.

It was an increidible comeback.

At the end, when they celebrated their title, it was a little crembarrassinge when the French president Emmanuel Macron hugged Teddy, only because he wanted to look "cool".

To say something is "a little cringe" is slang used by young people in the USA. It would work amongst friends, but talking to a more general audience I would choose a more formal word.

During the very last wday, I went to Lilles, a city in France located in the North, to watch the little and the big final of handball.

I think you might mean semi-final and final (instead of little and big final).

The little semi-final was thrilling.

Both teams were platying very well and fianally, Spain won by 1one goal.

However, the final was way more closed, Danemuch closer. Denmark won by 11 goals, which iset the record of the easiest win.

I was disappointed because the atmosphere had came out to be incredible, there were supporters of both teams.

I'm a little confused by this sentence. I think you mean you were disappointed because it was such an easy win...but what did it do to the atmosphere? It started incredible but then it wasn't? Wouldn't it still have been incredible for the Danish fans? Maybe you mean "the atmosphere had promised to be incredible, with supporters of both teams."

I hope you enjoyed reading my text!

I did - and learned more about a bit more about judo and handball.

Please tell me what you thought of my English and give me some subjects I could talk about!
