A Chinese fitness content creator has seen her sponsorship agreement terminated and her marathon finish annulled after evidence emerged that she completed part of the Berlin Marathon on a bicycle rather than on foot. The incident has reignited debate about honesty and verification in the increasingly commercialised world of endurance running influencers.
Sun Yuanyuan, who posts under the handle Abeeeer on Chinese social media platforms, had publicly celebrated a personal best time at the Berlin Marathon, held in late September. A personal best, or PB, is one of the most prized achievements for amateur distance runners, representing the fastest time they have recorded over a given distance. For influencers who document their training online, such results often translate directly into credibility, followers and brand partnerships.
That credibility unravelled after an Instagram account dedicated to scrutinising race times posted by fitness personalities published an image appearing to show Sun on a bicycle between the 35-kilometre and 40-kilometre marks of the 42.2-kilometre course. The image suggested she was riding on the back of a bike being pedalled by another person, rather than running under her own power.
The same account also shared a breakdown of her split times, the recorded durations for each five-kilometre segment of the race. According to that data, Sun's pace accelerated noticeably during the section where she was allegedly on the bike, a pattern that would be difficult to explain through normal running alone, particularly late in a marathon when most competitors are slowing down.
Facing mounting evidence, Sun issued an apology on Rednote, a Chinese social media platform popular with lifestyle and fitness creators, where she has accumulated roughly 520,000 followers. In her statement, she acknowledged violating race rules and offered no defence for her conduct. She explained that she had been feeling physically unwell during the race but stressed that illness could not justify what she did.
Sun described her decision to accept a lift as an attempt to take a shortcut, conceding that it showed disrespect both to the fairness of the competition and to the spirit of marathon running. She also admitted that she had deliberately hidden what happened, saying she felt profound guilt about her actions. The apology was subsequently shared by the account that had exposed the discrepancy.
The consequences were swift. Brooks, the American running shoe manufacturer, confirmed to the BBC that it had ended its relationship with Sun. In a statement, the company said it believed running should be rooted in integrity, fairness and respect for competition, and that after verifying the facts it had terminated its arrangement with the individual and addressed the matter publicly.
Marathon organisers also acted, disqualifying Sun's finish time. Disqualification typically removes a runner from official results and can carry further sanctions, though the source material did not specify any additional penalties. The BBC reached out to the Berlin Marathon for comment but had not received a response at the time of reporting.
The exposé came from an Instagram account calling itself the Official Marathon Time Integrity Unit, or OMTIU. The page has positioned itself as a watchdog against what it describes as a growing trend of GPS-based fabrication, selective display of data on the fitness tracking app Strava, and misleading public relations claims among marathon runners, with fitness influencers singled out as a particular concern.
In its mission statement, OMTIU said it exists to protect the integrity of the sport by ensuring that the times athletes share publicly reflect the times they actually ran. At the same time, the account's Instagram biography labels it as satire, a detail that adds a layer of ambiguity to its role: it functions simultaneously as an accountability project and as commentary on the culture it monitors.
The episode highlights a structural tension in the influencer economy. Brands invest heavily in personalities whose appeal rests on demonstrated athletic achievement, and audiences often treat race results as objective proof of that achievement. When verification depends largely on self-reported data and photographs, the incentive to exaggerate or conceal can be significant, and the damage when exposure occurs can be immediate and lasting.
For Sun, the fallout spans several fronts: a lost sponsorship, a disqualified result, and a public admission of dishonesty visible to more than half a million followers. For Brooks, the termination signals an effort to protect its association with authentic athletic performance. For the broader running community, the case adds to an ongoing conversation about how races, platforms and sponsors can better verify results in an era when reputation is built and dismantled online.
