athryn Serra figured out how to succeed in international rowing long before she first donned the black-and-white uniform of the Harvard-Radcliffe rowing team, competing in — and winning — various competitions for the United States’ junior teams while in high school.
In her first two summers competing for the United States at the U23 World Rowing Championships as an undergraduate, the Harvard-Radcliffe heavyweight rower raced in the eight and came home with a pair of silver medals. Serra was comfortable in the boat, comfortable with sweep rowing, and, most importantly, successful at the highest level.
She wasn’t complacent, however, and for her final summer at the U23 level, the now-senior decided to leave that comfort behind and venture into new waters.
“I just was like, whatever. It’s my last year. I’m gonna try something completely new,” Serra recalled.
That something was the quadruple sculls, a four-person boat in which each rower holds two oars, a stark contrast to the single oar Serra was accustomed to in the eight. In fact, the Miami, Fla., native had barely sculled since high school.
The decision came with substantial risk. The United States has traditionally found more international success in the eight than in the quad, and Serra knew switching boats could jeopardize her chance at racking up another medal.
“I love to win. I hate losing,” Serra said. “But sometimes, it’s worth it to do something that you’re not good at and work at it every single day, and get better and better.”
Serra’s gamble eventually paid off.
Alongside Sumner Kerr, Madison Kieft, and Lila Henn, Serra secured gold in the women’s quadruple sculls at the 2026 U23 World Rowing Championships in Duisburg, Germany. The victory gave the United States its first medal in the event at the U23 World Championships since 2007.
Finally, the one thing that eluded Serra for three summers was hers: a world championship.
“I was not expecting that at all,” Serra said. “It was so cool. It was insane.”
While one might think collecting a gold medal is standard procedure for a world-class rower at Serra’s level, that could not be further from the truth. Months of learning and dedication to a new category were essential for Serra as she prepared for the unfamiliar competition.
After years spent in sweep boats, Serra had to reacquaint herself with controlling an oar in each hand, doing all she could to overcome muscle memory gained from many years in the eight. Small, technical details that had long been instinctive in the eight suddenly required more attention in the quad.
“I had to get used to the second hand, like feathering the blade with the other hand,” Serra said. “I’d forget sometimes and get stuck.”
That unfamiliarity followed the American quad all the way to the starting line of the U23 World Championship final, and Serra knew the opening strokes would be one of the crew’s biggest vulnerabilities.
Starting from a dead stop, the rowers needed to accelerate the boat rapidly to build a lead before settling into their race rhythm, but competing against strong European crews with considerably more sculling experience, the Americans struggled to match their speed off the line.
“We started off maybe even last in the beginning,” she said.
She remembers being nervous, but she also knew the race would not be decided there. The quartet continued to push along while trying to make up as much distance as possible.
Once the Americans settled into their base rhythm, Serra watched the distance between their boat and the crews ahead disappear. By the middle 1,000 meters, the nerves had given way to something else.
“I was like, ‘Oh my gosh, we’re gonna walk through them,’” Serra said.
Sure enough, the Americans did. Soon, the U.S. boat had moved not just into the lead, but into open water.
“We’re not going back,” Serra remembered thinking. “I don’t want to leave them any room to sprint on us.”
The Americans crossed the line first, converting Serra’s experiment outside her comfort zone into a World Championship gold medal, her first as a member of the U23 national team.
The mentality behind that decision — willingly choosing something difficult simply because it is difficult — is hardly new for Serra.
Long before she became a world champion rower, she bounced between sports while growing up in Miami. She played basketball, ran cross country, and played tackle football as the only girl on the team. By the age of 12, she was already running half-marathons. Eventually, a middle-school friend introduced Serra to rowing, and she quickly fell in love with the sport that would go on to drastically impact her young adult life.
“I love how gritty you have to be and how mentally tough it is,” she said. “Rowing is just another level. You’re just in so much pain, and you have to love it.”
“I love being in, like, suffering and knowing, or trying, to outsuffer other people,” she added. “That sounds insane, but I love it.”
That drive has become familiar to the teammates who train alongside her in Cambridge. Junior Claudia Chadwick described Serra as “motivated, selfless, inspirational, and driven,” pointing to the challenge of continuing to improve when there are few benchmarks left inside the boathouse for Serra to chase.
“Because she’s so good, there isn’t someone she can compare herself to, to make herself better,” Chadwick said. “But she still shows up every day and pushes herself to crazy limits, and she’s broken so many boathouse records, which is awesome.”
Now back in Cambridge, Serra is facing a different kind of challenge. A rib injury will prevent her from racing in this year’s Head of the Charles, forcing the senior to watch an event that has helped define her Harvard rowing experience from the docks of Weld Boathouse.
For Serra and many of the Harvard-Radcliffe rowers, the Head of the Charles is unlike almost anything else in rowing.
“The Head of the Charles is insane,” Serra said. “Rowing is kind of a niche sport, but at Head of the Charles, when everybody is watching, it feels so cool to have so many people watching your sport.”
Serra first experienced that atmosphere as a freshman, and since then, both her role on the women’s heavyweight team and her place in the rowing world have changed considerably.
Three years after competing in her first regatta, she enters her final collegiate season with considerably more hardware: a gold and two silvers at the U23 World Championships, First Team All-Ivy and All-American honors, and the title of USRowing’s 2026 U23 Female Athlete of the Year.
Despite all the accolades she has accumulated, Serra is not ready to end her rowing career.
For now, the senior’s immediate goal is simple: get healthy. Once she does, she’ll focus on donning the Black-and-White and returning for her final spring season in Cambridge, where she hopes to help her team punch a ticket to the NCAA Championships and, in particular, get her team on the podium at the Ivy League Championships.
After her time in Crimson comes to a close, Serra’s goals get even bigger. With her U23 career behind her, Serra hopes to make the jump to the senior U.S. national team next summer. To her, joining the national team is another step to her ultimate goal, the Olympics
“Probably,” Serra said when asked whether competing at the Olympics was a dream of hers. “It’s just, like, scary to say.”
Confronting scary things isn’t anything new for Serra, and for an athlete who spent her final U23 summer choosing the unfamiliar precisely because it scared her, it may be fitting.
After all, the last time Serra stepped outside her comfort zone, she came home a world champion.
