K-pop idols are known for their relentless dedication to performance, training, and physical endurance—but one rising star is taking her passion for fitness to a new level.
Danielle, a member of the popular girl group NewJeans, recently completed her first-ever marathon event, and her results are already making waves both within the K-pop community and among health and fitness enthusiasts.
The singer’s unexpected but inspiring athletic milestone took place during the 2025 TCS Sydney Marathon 10K, where she participated as a member of the Unknown Crew, alongside Korean singer and marathon veteran Sean of Jinusean.
An Impressive Debut: Danielle’s 10K Time Turns Heads
On September 3, Sean took to Instagram to share the exciting update, posting a heartfelt caption and a cheerful photo with Danielle at a scenic lake in Sydney, Australia.
The post revealed that Danielle had completed the 10-kilometer race in an impressive 47 minutes and 27 seconds, a feat made even more extraordinary considering she only began running just two months ago.
“Danielle’s first 10K race time was an impressive 47 minutes and 27 seconds! It’s truly amazing to achieve this record just two months after starting running,” Sean wrote, praising the idol’s rapid progress and natural talent.
“Congratulations on completing your first race… It’s so nice to see Danielle enjoying running.”
Danielle’s final placement was equally notable — she ranked 26th in the women’s 20–24 age category, showing competitive performance among seasoned runners.
A New Side to Danielle: Passionate, Disciplined, and Goal-Oriented
While fans have long admired Danielle’s cheerful personality, angelic visuals, and versatility on stage, this marathon experience offers a glimpse into her personal commitment to growth and self-discipline off-stage.
In the world of K-pop, where grueling schedules, strict rehearsals, and intense competition are the norm, it’s rare to find idols who make time for hobbies and personal development—especially something as physically demanding as long-distance running.
For Danielle, this accomplishment shows a multi-dimensional approach to her career. Beyond singing and dancing, she’s embracing new challenges and showcasing resilience that extends beyond the music industry.
It’s a message that resonates strongly with both her peers and her fans: that health, wellness, and personal fulfillment are all important parts of a modern artist’s life.
Who Is Sean and What Is Unknown Crew?
Danielle’s companion for this fitness endeavor, Sean, is a well-known figure in Korea’s hip-hop and entertainment scene, having debuted as part of the iconic duo Jinusean under YG Entertainment.
Over the past decade, Sean has become equally known for his charity work, philanthropy, and athletic challenges, often using marathon participation to raise funds and awareness for various causes.
Unknown Crew, the group he and Danielle participated with, is a casual yet focused running club composed of public figures and athletes who support each other in reaching physical goals while promoting a healthy lifestyle.
Danielle’s inclusion in the crew marks a significant and positive expansion of her public image, especially for a young idol still early in her career.
Fan Reactions: Pride, Inspiration, and Admiration
Danielle’s fans — collectively known as Bunnies — have flooded social media with supportive messages, admiration, and enthusiasm following the news.
Hashtags such as #Danielle10KRun, #NewJeansFitnessQueen, and #DanielleMarathonDebut began trending shortly after Sean’s post was published.
Many praised her for showing a strong role model image, especially for younger fans who look up to her.
Others shared that her success inspired them to take on their own fitness goals — whether that be jogging, walking, or trying out a local 5K run.
“You can really tell how determined she is, not just in music but in life,” one fan tweeted. “Danielle has always been bright and passionate, but seeing her complete a 10K in under 50 minutes is just next-level inspiring!”
K-pop Idols and Physical Fitness: A Growing Trend
Danielle is part of a growing list of K-pop idols who are engaging in endurance sports and wellness activities to promote physical health and mental well-being.
From BTS’s Jungkook’s boxing workouts to BLACKPINK’s Jennie’s love for Pilates and yoga, many idols are no longer just symbols of beauty and fashion, but also ambassadors for health and strength.
Her decision to participate in a competitive marathon—rather than just endorse fitness brands—sets a genuine example of action over image.
It demonstrates that idols can pursue passion projects outside of music, and that fans are ready and willing to cheer them on every step of the way.
What’s Next for Danielle?
Following this achievement, fans are already wondering if Danielle will continue her marathon journey or possibly take on longer distances in future races.
While no official comments have been made about upcoming events, her strong debut hints that this could be just the beginning of a longer athletic journey.
For now, fans are celebrating a meaningful victory that goes beyond music charts and stage lights.
Danielle’s marathon finish represents personal growth, discipline, and the power of setting goals and crushing them — no matter how new or challenging.
From singing on global stages with NewJeans to crossing the finish line in Sydney, Danielle is showing the world that idols can be artists, athletes, and inspirations — all in one.
