A 530K-Follower Runner Took a Bike Ride in the Middle of a Marathon. Her Shoe Sponsor Took the Hit.
She posted her personal best. 4 hours, 53 minutes, 46 seconds.
The caption: 慢就是快. Slow is fast.
The fast part came on the back of a bicycle.
The Chinese fitness blogger Abeeeer, who has around 530,000 followers, ran the Berlin Marathon on 27 September and posted her new PB to Chinese social media the same day. Then a German fitness blogger shared a photo from the course, showing her riding on the back of a friend's bike near the 38 km mark.
The story tore through China's running community. By 4 October her sponsor, Brooks China, had publicly cut ties and apologised.
How the internet caught her
Runners did not stop at the photo. They pulled her official splits.
Her pace had been getting slower every 5 km, the way most people's does. Then from 35 to 40 km, the stretch where almost everybody falls apart, she clocked 30 minutes 49 seconds.
Her fastest split of the entire race. In exactly the section where she was photographed on the bike.
Her first explanation: she felt unwell, took the bike intending to reach the finish and withdraw, then felt better and went back to 38 km to run it properly.
Nobody bought it.
In the early hours of 3 October she apologised. She had broken the rules and would not make excuses, she wrote, and feeling unwell was never a reason to break them. She also admitted something more damaging than the ride itself: after the race, she had deliberately concealed it.
Her apology post drew enough reports that it had to be re-uploaded on 4 October.
The sponsor's problem
The photo showed her in Brooks shoes. She was not a fan who happened to buy a pair. She was a Brooks China partner.
Brooks China published a statement on 4 October. The substance of it:
The company opposes and will never tolerate breaking race rules or the spirit of the sport. Having verified what happened, it terminated the partnership immediately and will never work with her again.
Then the part that costs them something to say. Before the race, Brooks knew her training plan and her goal, signed her for this overseas race and supplied her gear. After the race, it checked her finish time and her photos and videos. It did not examine the race itself, and specifically not the split data.
Brooks called that its own 失察, its oversight, and apologised to runners and consumers. It committed to choosing partners more carefully and improving how it vets them and manages race risk.
Read those last two paragraphs again as a process description rather than a statement. The brand looked at the pictures. The pictures were lovely. The numbers were sitting in a public database the whole time, and nobody opened it.
Why this landed so hard in China
Brooks is a serious running brand, founded in 1914, with more than $1.3 billion in global revenue in 2024 and a Shanghai flagship opened the same year.
Its entire proposition to Chinese runners is that it is for people who really run. Which is precisely why this stung.
China's running community is enormous, obsessive and extremely online. Runners post watch data, compare splits line by line and argue about midsoles in Xiaohongshu threads that go on for days. They respect effort and they despise shortcuts. A brand selling itself on seriousness cannot be attached to a shortcut, even accidentally.
Brooks got several things right in the response.
It moved within a day of her apology. It avoided hiding behind "we are investigating." It took the blame onto itself rather than leaving it all with her. And it named the specific thing it failed to do.
That last point is the one worth copying. Chinese consumers pull vague apologies apart and keep going. A brand that says precisely what it missed, in this case the split data, gives the conversation somewhere to land.
The part that makes sport different
Here is what separates this from a normal influencer problem.
In most categories, an influencer's claim is a matter of taste. She says the serum improved her skin. Nobody can audit that.
In sport, the claim is a number, and somebody else publishes it. Marathons release splits for every runner. Strava and Keep record routes. Race photographers shoot the course. The claim your partner is making is sitting in a public database with her bib number on it.
That makes sports influencer marketing riskier than most, because her result becomes your marketing material. It also makes it the easiest category in the world to de-risk, because verifying her takes about ten minutes and a laptop.
Brooks had those ten minutes. So did everyone else, which is how a German blogger and a few thousand Chinese runners got there first.
Three things to do this week
Sort your China roster by claim type. Split it into partners making verifiable performance claims (a PB, a summit, a weight loss, a before-and-after) and partners doing taste content. Only the first group needs auditing. Most brands have 50-200 KOLs and have never sorted them this way, so "check everyone" fails on day one while "check these eleven" survives.
Hold amplification for 48 hours on any achievement post. The damage multiplier here was reposting. An influencer's lie is her problem until your brand account repeats it, at which point it becomes your claim. A short verification window before you amplify costs almost nothing and removes most of the exposure.
Your community is free audit capacity. A German blogger and a few thousand Chinese runners found this in days. Brooks could have found it in ten minutes. Chinese running communities will do this work whether you ask or not, so the question is whether you're reading them before they're writing about you.
