Michael Phelps stepped on the pool to inscribe his name as a synonym for the word ‘legend.’ Very few athletes in history have dominated their sport like the ‘Baltimore Bullet.’ With 28 Olympic medals, he redefined what was possible in the pool. While swimming allows for multi-event dominance, no one has ever approached his level of success and medal haul. His relentless work ethic, combined with a rare mix of endurance, power, and technique, set him apart as the greatest Olympian of all time. But alongside the rising Phelps stood a person as the strongest pillar. His coach and mentor, Bob Bowman.

The bond that grew between the coach and his disciple went beyond the typical athlete-coach relationship. Phelps himself has stated, “He is my dad. Like, I didn’t always have a dad growing up. So for me, having somebody there that was, one who believed in you, had confidence in you, but also help you along the way.” The two navigated years of intense training, Olympic triumphs, and personal challenges together. Bowman’s demanding coaching style played a crucial role in shaping Phelps into a generational talent. And now, after years of the athlete’s retirement, their dynamic is once again ready to make headlines.

Coach Bob Bowman was left stunned by Michael Phelps’ athletic caliber back in 2008

Recently, Bowman reflected on a jaw-dropping moment from Phelps’ training days, leaving fans in awe once again. Joining Digital creator and swimming enthusiast Kyle Sockwell for a candid conversation, Bowman went down memory lane. Speaking about the most extraordinary ‘alien-like’ athletic feat he had ever witnessed, Bowman took a trip back to 2008, just before the Beijing Olympics. During a routine practice set, Phelps produced something so remarkable that even his coach, who had seen it all, was left speechless.

“This is in 2008… A week before the Beijing Games,” Bowman recalled. “He did butterfly, and the first one, he was like 55.3, and I mean, he could not have swam easier… And then the second one, I was like, ‘Well, he’s still pretty easy. I wonder if he’s doing anything.’ He’s 53.6.” At this point, Bowman was still processing what was happening but then came the moment that left the entire training group stunned.

“But the third one was 51.6. From a push. In a practice,” Bowman revealed. The number was almost unfathomable: 51.6 seconds in the 100m butterfly, without a race start, in training conditions. He added, “Everything was like quiet. Everybody’s like, and other people had time to like, ‘Oh my God, was that 51.7?’ But yeah, it was 51.6.” Even for someone as decorated as Phelps, this was a performance that defied belief. 

Coach Bowman’s anecdote quickly made its way to Phelps, who took to social media to acknowledge it in his own lighthearted way. Sharing the story, Phelps reposted the reel on his Instagram story and wrote, “Guess @CoachBowman had me ready 🤷‍♂️🤣.” The brief response spoke volumes—Phelps himself seemed both amused and unsurprised by the memory, knowing full well the level he had reached at his peak.

Even years after retirement, moments like these continue to cement Phelps’ legacy as something beyond extraordinary. While his Olympic achievements are well-documented, it’s these behind-the-scenes glimpses that further illustrate just how rare his talent truly was. For Bowman, that 2008 practice session was confirmation that his star pupil was ready to make history. And Phelps? As always, he delivered. And now, as Bowman prepares another star of the water, the Frenchman Leon Marchand, he reflected on the grounds of difference between the legend and the young phenom.

Bob Bowman lays bare the stark divide between Phelps and Marchand

Bob Bowman has seen it all. From the rise of Michael Phelps to the emergence of Léon Marchand. And with it the nuances that set the two apart. Having coached both, the 59-year-old recently dissected their differences, offering an unfiltered perspective on what makes each swimmer unique. Speaking on The Exponential Athlete podcast, Bowman didn’t mince words, “The obvious differences are physical. Michael is this massive, strong, prototypical, you know, swimming machine… (Marchand) is not very physically imposing.”

But it wasn’t just about size. Their temperaments were polar opposites as well. While the Frenchman is known for his laid-back approach to training, Phelps was wired differently. “Michael is very Tiger Woods, incredibly intense about everything he does, and to do his job, he has to kind of get intense,” Bowman revealed.

This relentless drive often turned their coach-athlete relationship into a battleground. He added, “I think when you coach Michael, you had to be pretty strong with him sometimes. I had to, like, challenge him. And when he got challenged sometimes, he would push back on me; I would just push back harder, you know?”

Marchand, on the other hand, doesn’t require such confrontational coaching. He absorbs instructions without resistance, making for a smoother dynamic. And yet, despite these stark contrasts, both swimmers have thrived under Bowman’s guidance. One was the greatest Olympian of all time, and the other already carving his own golden path.
