We live for it. When I was probably like 10 years old, I had this dream of winning at the biggest stage of swimming. It just kept like repeating in my head every night. Some dreams fell too big. But if you can imagine it, you can actually chase it. I love being underwater. It's where I can feel connected to what I've been chasing for. There's this warm energy, like I'm diving into myself.""In Paris, on my last turn of my 400 IM, I could hear 15,000 people shouting my name, saying Leon, Leon, Leon. That was right before the race. I knew I could win this. I can just enjoy the moment, give it all and touch the wall. Success doesn't mark the end at all. It just shows you what's next, what's the next step. I think the dreamer inside me just keeps pushing forward. Truth is, there's no finish line in the race for excellence," he added.Leon Marchand also made history as the flame bearer during the closing ceremony of the 2024 Paris Olympics.
