When you compete in something as long as I have -- remember, I swam in my first Olympics before I was old enough to drive -- you see just about everything. The aging superstar chasing one more Olympic gold, the teenage record holder who everyone believes is the next big thing. Some succeed. Most fail. Maybe theyre not good enough, dont want to put in the work, or dont care about winning enough to truly push their body to its limit.And then theres Katie Ledecky. It was two years before the 2012 London Games when I first started paying attention to her. Every time she got in the water, it didnt matter what time of year it was, how rested she was, where she was swimming, who she was swimming against -- she was cranking best times, national records. It was incredible. I remember thinking, this girl might be the real deal.But I wanted to see it on the big, big stage. Could she do it in the Olympics?In London, Katie was just 15 years old -- the same age I was at my first Olympics in Sydney. She was quiet, kind of kept to herself. But on the final day of competition, in the 800 freestyle, she won gold by more than four seconds. I won gold in the 100 fly earlier that night and had just received my medal when Katies event began. As I was walking through the interview area, reporters began asking me questions that I didnt even answer. Instead, I pointed to the monitor where Katie was crushing it.This past summer in Rio, she backed it up with four more golds. Right now, shes untouchable. There are swimmers who might push her, but no one is going to beat her. I remember what that feeling was like; its a great place to be. You know that if you put in the work, the reward is going to be there at the end. The challenge becomes longevity. How long can you keep it up?But no one is better prepared for this than Katie. Shes that much better than everybody else. When I watch her swim, its like an art. Its beautiful. She maximizes her distance per stroke. Its just something you dont see in swimming. Beyond that, shes one of the hardest-working people Ive ever seen in training camp. She will swim with the guys and make them look like theyre standing still. I did a set with her once in Colorado Springs, Colorado, at the Olympic Training Center. We were supposed to go together, but I was thrilled when she decided to lead a lane because I didnt want to get my ass whipped. Shes just special.And beyond that, mentally, she never lets up. She goes all out the entire race. Her mentality is, Im going to crush this field as much as I possibly can. In the first 100 meters, the race is over. Hell, in the first 50 its over. She makes the statement and then backs it up. Its just so remarkable.Yet away from the pool, with her teammates, shes as laid back as anyone. Shes talking, laughing, messing around. Then she gives a few high-fives, goes out and absolutely destroys the rest of the world. Its amazing to watch. You just dont see people like her in the sport. I know. And for me to have shared part of my career with someone so dominant and dedicated, and yet still so determined, is an honor. I mean it. Im a fan of this sport as much as anyone. And I cant wait to see what she does next.More on Katie Ledecky? What makes Olympic swimmer Katie Ledecky remarkable Story ?? On this night, appropriately, Ledecky eclipses Phelps?Story ??
