East Coast Park duathlon: Woman bloodied & bruised after another biker apparently hit her & rode off - Mothership

The organiser said their on-ground safety and medical teams responded immediately.

A woman who took part in the TriFactor Duathlon on Sep. 13, 2026 was allegedly left badly injured after a fellow rider collided into her.

The other rider apparently did not stop to check on her after the collision, and continued riding on, according to the woman's sister.

The sister posted about what happened on Instagram, seeking witnesses who might have information to identify the rider for a police report.

In a subsequent update, the sister said the victim has made a police report.

The police confirmed that a report was lodged and they are looking into the matter.

In response to Mothership's queries, the management team of TriFactor, who organised the duathlon, said they are aware of a cycling incident involving a participant at the event.

The TriFactor Duathlon, which follows a run–bike–run race format, was held at East Coast Park on the morning of Sep. 13.

According to the victim's sister, the incident happened at around 9:30am, during the cycling leg of the race.

The victim recalled a male participant overtaking her from the left, which caused the collision.

After he allegedly rode away, an ambulance brought the victim to Changi General Hospital's emergency department.

She was apparently sent to the hospital alone, without her belongings too, which made the sister "extremely concerned".

The Instagram post included a photo of the victim with a bloodied lip and bruises on parts of her face.

The sister also reshared what appeared to be an Instagram story by the victim post-incident.

"Apart from the damage to my bike and sunglasses, I'm now dealing with quite a bit of pain and injuries," the victim wrote.

She recounted that she had been thrown off her bike, and there was a lot of blood on the ground.

The victim wrote that she was sad not to have completed the race, and scared and ashamed to talk publicly about what happened.

Her family has asked her to return to Kuala Lumpur, so that they can look after her.

She added that she was being taken care of, and hopes to come back stronger.

Initially, the sister said TriFactor Asia did not provide her with a "proper response" nor answered her calls.

She later updated that a person from the company contacted the family regarding the incident.

"At this point, our intention is not to place all the pressure or responsibility on TriFactor Asia.

We simply hope that they can cooperate and assist with the investigation so that the matter can be properly looked into."

TriFactor's management team told Mothership that there were established safety and medical protocols in place at the event.

"Our on-ground safety and medical teams responded immediately, adhering strictly to established protocols.

Preliminary reviews confirm all standard operational controls were fully executed with no operational lapses."

They added that they are in direct contact with the participant to offer their full support towards her recovery.
