Shereen Samson Vallabouy's Hamstring Injury: A Setback for Malaysia's 400m Champion (2025)

In a heartbreaking turn of events, Malaysia’s sprinting sensation Shereen Samson Vallabouy has been forced to withdraw from the SEA Games in Bangkok, shattering her dreams of defending the 400m title she claimed in 2023. But here's where it gets even more devastating: medical tests have confirmed that her hamstring injury, sustained during a training mishap, hasn’t healed enough for her to compete safely. And this is the part most people miss—her absence leaves Malaysia with just one athlete, Chelsea Bopulas, in the women’s 400m event, a race Shereen has dominated regionally with her national record of 51.79s.

The 27-year-old sprinter suffered a three-centimetre tear in her left hamstring after a fall during a 4x100m training session at Universiti Putra Malaysia in early November. Despite undergoing rigorous rehabilitation at the national sports institute (NSI), follow-up assessments this week dashed her hopes of a timely recovery. Her withdrawal was confirmed by her mother, Josephine Mary, a former national champion in the 400m and 800m events.

Shereen’s absence is a significant blow, as she was slated to compete not only in the 400m but also in the women’s 4x100m, 4x400m, and mixed 4x400m relays. This ambitious lineup was part of a grueling training regimen she had been following since returning from the United States in October, under the guidance of her American coach Derrick White and local trainer Amir Izwan.

Here’s where it gets controversial: While some might argue that pushing through injuries is part of an athlete’s journey, Shereen’s decision to prioritize her health over competition raises important questions about the balance between ambition and well-being. “It breaks my heart that I can’t be there,” Shereen admitted. “I wanted so badly to defend my gold, but my body isn’t ready. The hamstring has improved, but not enough to compete safely at this level.”

Her 2024-25 season has been a rollercoaster, marked by both triumphs and setbacks. She kicked off the season with a win at the Embry-Riddle Running Elements Classic in Florida, clocking 53.72s. However, illness derailed her performance at the Asian Championships in Gumi, where she ran a fever and finished with a time of 54.80s in the heats. Subsequent tests revealed deeper health complications, forcing her to scale back her training for several months.

“After Gumi, she felt weak all the time, no matter how much she tried to recover,” Josephine shared. “But she worked on it and gradually got back to training. This hamstring setback is unfortunate, but she will come back stronger.”

Even before the injury, retaining her SEA Games gold was never going to be easy. Thailand’s Josephine Chinenye Onuorah has been in top form, consistently running sub-53-second times in the United States this season. Vietnam’s Nguyen Thi Ngoc (53.12s), Thailand’s Benny Nontanam (53.15s), and Vietnam’s Le Thi Tuyet Mai (53.37s) have also been formidable contenders.

Despite the setback, Shereen remains optimistic. “This is just a pause,” she declared. “My goal is to return fully healthy, rebuild, and get back to the form I know I’m capable of for the Asian Games and Commonwealth Games.”
