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 ??

LONDON -- As unified middleweight titleholder Gennady Golovkin prepares to make his 17th defense, against Englands Kell Brook, theres a third wheel muscling in on the attention being paid to their fight: lineal middleweight champion Canelo Alvarez.Golovkin, a knockout machine and perhaps boxings most feared fighter, has come to the birthplace of boxing to defend against Brook on his turf on Saturday (HBO, 5:30 p.m. ET/PT with a replay at 10 p.m. ET/PT) at the sold-out O2 Arena because Alvarez has steadfastly refused to fight him, going so far as to relinquish his sanctioning organization belt rather than fulfill a mandatory obligation to Golovkin in a megafight.The typically mild-mannered Golovkin normally doesnt utter a negative word about anybody, but Alvarezs gamesmanship clearly has annoyed him. He has been more outspoken about the situation than ever before.Its like a circus, too many clowns, Golovkin said. Canelo knows he doesnt want to fight me. Why do you keep talking then?Although Alvarez won the lineal middleweight title, he did so at his preferred catch weight of 155 pounds against Miguel Cotto last November and continues to resist a move to 160 pounds. Instead of agreeing to face Golovkin, as he appeared to do following his huge knockout of Amir Khan, a welterweight who moved up, in a May defense, Alvarez is retreating to junior middleweight. He will return to 154 pounds, where he once held titles, to challenge titleholder Liam Smith, Brooks countryman, on Sept. 17 (HBO PPV) at AT&T Stadium in Arlington, Texas.Golovkin, who has knocked out 22 consecutive opponents since 2008 and owns the best knockout percentage in middleweight title history (.914), is resistant to any criticism that he is picking on a welterweight in Brook, who owns a world title and is considered by many No. 1 at 147 pounds, the same way Alvarez did with Khan.Canelo was the middleweight champion and chose Amir Khan, said Golovkin, who has been rebuffed by a whos who of the middleweight division in recent years. We didnt choose Brook. He chose me. My goal is all the middleweight belts. Canelo is not ready until next year or maybe not for five years.The 30-year-old Brook (36-0, 25 KOs) had no fear of facing Golovkin (35-0, 32 KOs), jumping at the chance when offered the fight after a bout between GGG and another Brit, middleweight contender Chris Eubank Jr., fell apart in the final moments when Eubank allowed the deadline to pass without signing.This fight is much bigger than if I faced Eubank, Golovkin said. [Brook] is a champion, hes undefeated, he is more famous. Who knows Eubank? Everybody understands he is 50 percent clown, 50 percent fighter. OK, he says hes ready, hes fighting. [Then] hes not ready, more dancing, more talking, trash talking. Hes like clown.Brook is moving up two weight divisions in an attempt to become the third reigning welterweight titlist to win a middleweight title in boxing history, joining all-time greats Sugar Ray Robinson and Carmen Basilio. Kazakhstans Golovkin, 34, who fights out of Santa Monica, California, respects the fire Brook has shown in accepting this difficult assignment.Everybody has risk in boxing, Golovkin said. Hes moving up and taking that risk, and for that I have a great deal of respect for him. Brook is dangerous. He has a very high boxing IQ and were fighting in his country.Golovkin, however, said he has little respect for Alvarez after the way he led him to believe they would fight on next weeks Mexican Independence Day weekend.After Alvarez knocked out Khan, he called Golovkin into the ring, telling him to his face that Mexicans dont f--- around and seemingly promising they would fight next.At the postfight news conference, Alvarez said he would even fight GGG at 160 pounds, and his promoter, Golden Boys Oscar De La Hoya, put on an over-the-top display, telling the media that Golovkin promoter Tom Loeffler, of K2 Promotions, should make sure his phone was on because he would be calling him the following day to open discussions.But instead of trying to make the fight, Alvarez vacated his title, which interim titlist Golovkin inherited, and eventually signed to fight Smith, who was all but unknown outside the United Kingdom. Alvarez also promised that he would fight Golovkin next September, although there is no formal agreement and few believe him.dddddddddddd.Golovkin does not think it will happen and that Alvarez will continue to make him and the public wait for the big fight.Impossible, he said of Alvarez agreeing to fight him in 2017. But maybe if I look bad with Kell Brook or another guy and hes ready, but [only] if I look bad.An Alvarez-Golovkin fight looms as one of the biggest in boxing, but it could play out like the frustrating Floyd Mayweather-Manny Pacquiao fight, which took years to make. Golden Boys Eric Gomez, promoted this week to president of the company, has said repeatedly to ESPN.com that Alvarez will fight Golovkin, but he would not give a timetable.That is the biggest fight, with Canelo, Golovkin said. But he stepped back. He is like loser. After Khan he said, OK, G, come into the ring. Im asking, What you want? He said, Im OK, I looked good. We fight. Then at the press conference, he says, I am ready, give me gloves. Im ready right now. Too much talking. This is not true. He is saying, I am ready [but] maybe not next fight. Next year. Everybody understands he said I am ready right now. I gave him too much attention. I do not believe he is ready.I know him. We trained together, like, three training camps. We sparred together. I know his team. He is not ready. I told him, Please just give me my belt, and thats it. He says OK and steps back. Too much talking, too much trash talking. Just give me my belt and get out of here. Maybe its business. After [the Khan] press conference I lost respect for him because he talks too much.Abel Sanchez, Golovkins trainer and the 2015 Boxing Writers Association tr
