The pursuit of a personal record in a marathon demands months of rigorous training, early mornings, punishing mileage, and immense psychological resilience. For everyday runners and elite athletes alike, the 26.2-mile distance is a definitive test of endurance where shortcuts simply do not exist. This reality makes the discovery of deception on the course particularly grating to the global running community. When a high-profile fitness personality claims a hard-fought personal best only for photographic evidence to reveal they rode a bicycle during a critical stretch of the race, the fallout is swift and unforgiving.
This is precisely what unfolded for popular social media influencer Sun Yuanyuan, widely known to her more than 500,000 followers on the Chinese platform RedNote under the moniker "Abeeeer." Following the conclusion of the Berlin Marathon on September 26, 2026, Yuanyuan found herself at the center of an international sporting scandal. What began as a celebratory post about her race performance quickly unraveled into a public relations crisis after photographic and digital evidence proved she had bypassed a significant portion of the course on the back of a bike. The ensuing backlash has not only severely damaged her online reputation but has also cost her lucrative corporate backing.
The controversy erupted when sharp-eyed observers and race integrity officials scrutinized Yuanyuan’s split times and race-day visuals. Documentation emerged showing the influencer riding side-saddle on a bicycle rather than logging her miles on foot during a grueling section of the course situated between the 35-kilometer and 40-kilometer marks. In marathon running, this particular phase of the race is notoriously difficult—often referred to by runners as "the wall," where physical and mental exhaustion peak.
While Yuanyuan had initially touted her finish and celebrated her supposed personal best on social media, the Official Marathon Time Integrity Unit told a different story. Cross-referencing her race data revealed an undeniable correlation: her mysteriously lightning-fast split times directly mirrored the moments she was captured hitching a ride on two wheels rather than relying on her own stamina. As the incriminating images circulated rapidly across various digital platforms, Abeeeer went viral for all the wrong reasons, transforming overnight from an inspirational fitness voice into a cautionary tale of online deceit.
The revelation struck a raw nerve within the running community, where authenticity and adherence to the rules are held as sacred tenets. Marathons level the playing field, requiring every participant to traverse the exact same distance under their own power. When an influencer with a massive audience attempts to manipulate that reality for digital clout, it undermines the genuine efforts of thousands of runners who train for months in the rain, wind, and heat to legally earn their finisher medals.
Sun “Abeeeer” Yuanyuan Apologizes for Cheating at the 2026 Berlin Marathon
Faced with mounting proof and unrelenting public criticism, Yuanyuan was forced to reverse her initial stance. She abandoned her earlier narrative of athletic triumph and issued a formal apology for her unsportsmanlike conduct. In a statement published on October 3, 2026, she attempted to contextualize her actions by explaining that she had been "feeling unwell" during the latter stages of the race. However, this explanation did little to stem the tide of public disapproval or salvage her professional relationships.
The fallout was immediate in the corporate sphere. Athletic footwear and apparel brand Brooks China, which had maintained a commercial partnership with the influencer, moved swiftly to distance itself from the scandal. Recognizing the potential damage to its brand integrity among dedicated athletes and casual runners alike, Brooks China officially terminated its deal with Yuanyuan, severing all ties with the disgraced social media personality.
In her public apology, Yuanyuan made no attempt to justify her actions or dispute the overwhelming evidence against her. Acknowledging the gravity of her misstep, she wrote that she would "not make any defense for the above behavior." She went on to describe her actions as "a very dishonest act" that directly violated the core "sporting spirit of fair marathon competition." Reflecting on the events of race day, the influencer added that looking back at the incident left her feeling "deeply guilty."
For its part, Brooks China issued statements addressing the controversy directly to its consumer base. The company formally apologized to runners and loyal patrons of its products for the association with the scandal. Furthermore, representatives for the brand noted that the company would use the incident as a learning opportunity, vowing to thoroughly reevaluate how it selects future corporate partners, brand ambassadors, and athletic collaborators to ensure better alignment with the values of integrity and fair play that define the athletic community.
