At the finish line of the recently concluded 2025 TCS New York City Marathon, when Kenyan star Hellen Obiri (Hellen Obiri) crossed the line in 2:19:51 —an astonishing time that shattered a 22-year-old course record—the whole world's attention was focused on this great champion.
However, among the cheering crowd, a woman wearing On Athletics Club (OAC) coaching apparel was already in tears.
She was Laura Thweatt (Laura Thweatt). Ten years ago, she made her name on this course as the "America's strongest female debut marathoner"; ten years later, she returned to New York as an assistant coach and personally led her athlete to the top of the podium.
This is a story about retirement, uncertainty, reinvention, and rebirth. For Laura Thweatt, New York in 2025 was more than just a race — it was a deeply meaningful “homecoming” that marked the triumphant beginning of the second chapter of her career.
The story goes back to the end of 2024. At that time, Laura Thweatt officially announced her retirement from the professional circuit. With a personal best of 2:25:38 (2017 London Marathon), Thweatt — across a professional career spanning more than a decade — had won the 2015 USA Cross Country title and finished fifth at the 2020 Olympic Trials, just one step away from an Olympic spot.
However, repeated injuries and the end of sponsorship deals forced her to face a harsh reality. "Those were a very difficult two or three years," Thweatt admitted in an interview with the New York Road Runners (NYRR). "I was trying to decide whether I wanted to continue such an intensely serious competitive life. To be honest, I felt very lost."
Just as she had expressed uncertainty about her future on social media, a phone call changed her trajectory. On the other end was Dathan Ritzenhein — himself a former elite runner turned top coach — head coach of On Athletics Club (OAC), one of the world's leading distance training groups.
Ritzenhein extended an olive branch to Siweite, saying OAC needed a coach who could be "boots on the ground" to lead the club's expanding road-running group. For Siweite, who has more than a decade of high-school coaching experience (including a stint as assistant coach of Monarch High School's cross-country team in Colorado), it was more than a job — it was where her passion truly belonged.
In March 2025, Siweite officially joined the OAC coaching staff, becoming the "guide" for world-class athletes such as Obiri and Joe Klecker (Joe Klecker).
If joining OAC was the start of her transition, then the 2025 TCS New York Marathon was Si Weite’s “final exam” as a coach. The task she took on was formidable: assisting two-time Boston Marathon champion Hellen Obiri in defending her New York title, and helping American track star Joe Klecker complete his marathon debut.
During the four-month preparation period, Si Weite became the athletes’ strongest support. She stopped chasing her own pace and kept her weekly mileage to just 15 to 20 miles, simply so she could accompany the team during warm-ups or observe their condition on easy runs. “That allowed me to take a step back and completely let go of my identity as an athlete, but I could still be part of it in another way because I still love the sport,” Si Weite said.
Hellen Obiri’s pre-race form left Si Weite both excited and nervous. The two-time Olympic 5000m silver medalist and 2024 Paris Olympics marathon bronze medalist had shown an unprecedented level of dominance in training.
On race day, Obiri delivered a near-perfect performance. She not only successfully defended her title, she also ran a 2:19:51 staggering time. This not only improved her personal PB, it also shattered the course record of 2:22:31 held by Margaret Okayo since 2003.
Siweit recalled Obiri's post-race feedback: "Hellen told me that, before she decided to make her move in the final stages, she felt incredibly strong. She said, 'I know this has been one of the best training cycles I've ever had; I'm in a condition I haven't reached for a long time. I've regained my confidence, I know I'm the best, I can win.'"
At the same time, another OAC standout, Joe Klecker, completed his transformation under the watch of Sweat. The son of former U.S. 50-mile record-holder Barney Klecker and 1992 Olympic marathoner Janis Klecker, Joe carried huge expectations.
In the end, Klecker finished in 2:10:37 , placing 10th overall and third among American competitors. For a debut, this is an extremely solid result, demonstrating the success of the Sweat and Ritzenhein training system.
Siweite's success is about more than just results; it also carries symbolic weight as a female coach operating at the top level of professional sport.
Female coaches at the elite level remain rare in distance running. "In my entire career, I’ve hardly ever worked with a female coach," Siweite reflected. "So getting the opportunity to have a female coach at this elite level is really cool for me."
She and Obiri have built a deep bond that goes beyond coach and athlete. Their relationship is based not just on tactics and training, but on mutual understanding and empowerment between women. "Hellen is fun, has a great attitude, and truly enjoys the process. Even after more than 20 years in her career, she’s still full of passion," Siweite said. "She’s definitely becoming my friend and is another woman in this sport who inspires and empowers me."
This subtle emotional connection and unique perspective may be the crucial piece that enables the OAC team to perform at a high level under pressure.
For Laura Siweite personally, the New York Marathon holds special significance.
"I was at the finish line with Dasen; I cried when Hailun crossed the line, and I cried again when Qiao finished," Siweite recalled. "It was the culmination of four months' work. Although it's only 26.2 miles, over this uncontrollable distance you and the athlete pour everything into it."
It was a different satisfaction than crossing the line herself. Once, she was the anxious young runner on the Staten Island starting line; now, she is the tactical mastermind orchestrating things at the Central Park finish.
On Athletics Club's global expansion in recent years has been evident, and the addition of Laura Swet fills a crucial role in its coaching staff.
As the 2026 season approaches, we have reason to believe that Laura Thweatt will play an even more important role at OAC. And Hellen Obiri's sensational run in New York may be just the beginning of this all-female mentor-protégé duo's conquest of the world.
For Laura Thweatt, hanging up her running shoes doesn't mean stopping. She's simply chosen a different way to keep racing down the road to greatness.
