Cody William Miller, born on January 9, 1992, in Billings, Montana, is a retired American competitive swimmer renowned for his prowess in breaststroke events.
He carved out a distinctive path in the sport, rising from a high school swimmer in Las Vegas to an Olympic medalist.
Miller’s journey was marked by personal challenges, including body image struggles and family hardships, such as the loss of his father to addiction just months before the 2016 Olympic Trials.
He transitioned from collegiate dominance at Indiana University to professional success, competing for DC Trident in the International Swimming League.
Beyond the pool, Miller became a social media sensation through his YouTube channel “Cody Miller Adventures,” where he vlogged his training, daily life, and motivational insights.
In December 2024, after a final meet at the Indiana University Natatorium where he set a personal best in the 100-yard backstroke, Miller announced his retirement from professional swimming.
Siblings
Cody has a younger sister, Catie Miller, who followed in his footsteps as a talented swimmer specializing in breaststroke and individual medley events.
Growing up in a family that relocated from Montana to Las Vegas, Nevada, the siblings were both immersed in the sport from an early age, with Catie drawing inspiration from her brother’s achievements.
She competed at the collegiate level for Duke University from 2014 to 2018, where she honed her skills in the same disciplines that propelled Cody to international fame.
Career
Miller’s swimming career began unconventionally in Las Vegas, where he trained with the Sandpipers of Nevada club team after attending Palo Verde High School.
He initially joined the sport to spend time with friends, but his natural talent in breaststroke quickly emerged, leading him to set multiple age-group records, including USA Swimming National Age Group marks in the 100-yard and 200-yard breaststroke for the 15-16 age division.

Enrolling at Indiana University in 2011, Miller flourished under coach Ray Looze, becoming a three-time Big Ten champion in both the 100-meter and 200-meter breaststroke events.
His collegiate highlights included four All-America honors in his junior year, setting school records in relays and individual events, and earning the distinction as the third swimmer in Big Ten history to win three consecutive 100 breaststroke titles.
After graduating, Miller turned professional and burst onto the international scene at the 2014 Short Course World Championships in Doha, Qatar, securing a silver in the men’s 4×100-meter medley relay and a bronze in the 4×50-meter medley relay, the latter in an American-record time.
The pinnacle came at the 2016 Rio Olympics, where he claimed bronze in the 100-meter breaststroke with a national and Americas record of 58.87 seconds, followed by a gold in the 4×100-meter medley relay alongside legends like Ryan Murphy and Michael Phelps.
Post-Rio, Miller continued competing at high levels, earning five World Championship relay medals between 2014 and 2017, including two golds.
He adapted to challenges like the COVID-19 lockdowns by installing a backyard Endless Pools Elite for training and represented the U.S. at the 2020 Tokyo Olympics, though without individual medals.
Accolades
At the collegiate level, Miller amassed multiple Big Ten titles, including three consecutive victories in the 100-meter breaststroke from 2012 to 2014, and set enduring school records at Indiana University in events like the 200-meter individual medley and various relays.
His four All-America certificates in 2013 highlighted his dominance, with placements in the NCAA Championships for the 200 IM, 200 breaststroke, and medley relays.
Internationally, Miller’s breakthrough at the 2014 Short Course World Championships yielded silver and bronze relay medals, complemented by his first national title in the 100 breaststroke that year.
The 2016 Rio Olympics cemented his legacy with an individual bronze in the 100-meter breaststroke—breaking the American record—and a gold in the men’s 4×100-meter medley relay, contributing to the U.S. team’s ninth consecutive Olympic victory in the event.
Over his career, he collected seven World Championships and Olympic medals: three golds, two silvers, and two bronzes across long and short course formats.
As a record-breaker, Miller held the world mark in the men’s 4×50-meter freestyle relay and mixed 4×50-meter freestyle relay, alongside the American record in the long-course 100-meter breaststroke until 2016.
He was also an eight-time American record holder overall and a key member of the U.S. National Team.
