FIT AND FULL OF LIFE: RUNNER, 24, DIES DURING HALF MARATHON JUST MONTHS AFTER TRAINING WITH HIS GIRLFRIEND FOR CHARITY

A 24-year-old runner has tragically died after suffering a sudden cardiac arrest during the Cardiff Half Marathon, leaving his family, girlfriend and friends devastated.

Ross Williams-Griffiths, from Bargoed in Caerphilly, Wales, had spent months preparing for the 13.1-mile race alongside his girlfriend, Katie Bowen.

The couple were taking part together to raise money for Tenovus Cancer Care, a Welsh charity supporting people affected by cancer. Affectionately known as “Team Griff-Bow”, they had hoped their efforts would help make a difference to others.

But what should have been a day of achievement and fundraising ended in unimaginable heartbreak.

Ross suffered a sudden cardiac arrest during the race on Sunday, October 4, 2026. Despite the efforts of medical teams, he sadly died.

His family released an emotional tribute on October 21, remembering him as a young man who brought laughter, loyalty and warmth wherever he went.

A YOUNG MAN WHO LOVED LIFE

Ross was described by his loved ones as active, fit and full of life.

He embraced every opportunity to spend time with family and friends, approaching everything he did with enthusiasm and determination.

Whether playing football, taking to the golf course, snowboarding, bodyboarding or preparing for another running challenge, Ross threw himself into life with energy and commitment.

His family said he was kind, generous and hard-working, and that he never had a bad word to say about anyone.

He also had a special ability to make people feel welcome wherever he went.

For those who knew him, Ross was much more than an enthusiastic sportsman. He was a beloved son, brother, partner and uncle whose presence brought happiness to the people around him.

His family said he had a bright future ahead of him, having already built a promising career with GE Aerospace.

At just 24, he had so many plans and experiences still waiting for him.

MONTHS OF TRAINING FOR A SPECIAL CAUSE

Running had become an important part of Ross’s life.

He had trained diligently for the Cardiff Half Marathon alongside Katie, preparing for the demanding 21-kilometre challenge.

The race was not simply about completing a personal goal. The couple were running to raise money for Tenovus Cancer Care, a cause particularly meaningful to them.

Their affectionate nickname, “Team Griff-Bow”, reflected the partnership they shared as they trained and prepared for race day.

Ross had also recently joined South Wales Striders, a local running club, alongside his brother Rhys and his brother’s fiancée, Jayde.

The club became another place where he could share his love of running with people close to him.

His family said he had approached the half marathon with commitment, enthusiasm and careful preparation.

They described him as a young man who loved being part of the running community and who took genuine pleasure in the challenges he set himself.

Nobody could have imagined the devastating outcome that lay ahead.

A TRAGEDY DURING THE CARDIFF HALF MARATHON

The Cardiff Half Marathon took place on Sunday, October 4, attracting thousands of runners to the Welsh capital.

During the event, Ross suffered a sudden cardiac arrest.

Run 4 Wales, the organisation behind the race, subsequently confirmed that a participant had died following the medical emergency.

The organisers praised the speed and professionalism of the event and hospital medical teams who responded.

Matt Newman, chief executive of Run 4 Wales, said the loss of a runner at one of its events was deeply felt by everyone involved.

He extended his condolences to Ross’s loved ones and said the organisation’s focus remained on supporting the family.

The exact medical cause of Ross’s death has not yet been established publicly, according to his family.

Although he was described as fit, active and healthy, his death has raised important questions about sudden cardiac arrest and the need for greater awareness of heart health among young people.

His family hopes that sharing his story may help others recognise the importance of seeking appropriate medical advice and considering heart-health screening.

HIS RUNNING CLUB REMEMBERS A MAN WHO ALWAYS SMILED

Following the news, South Wales Striders paid tribute to Ross, remembering him as someone who always had a smile on his face.

The club said he attended its group runs alongside Katie, his brother and his future sister-in-law.

He was a pleasure to run with, members said, adding that they felt grateful to have known him.

Their words reflected the affection Ross had earned within the local running community in a relatively short time.

The club also encouraged runners to consider heart-health checks, highlighting that organisations such as Calon Hearts offer free screening for eligible younger people.

For Ross’s friends and fellow runners, the tragedy has brought home how important it is to look after one another and to take heart health seriously, even among people who appear healthy and physically active.

HIS FAMILY’S HEARTBREAKING TRIBUTE

In a statement released through Run 4 Wales, Ross’s family described the devastating impact of losing someone so young.

“Ross was a young, fit and healthy man who loved running and being part of the community that surrounded it,” they said.

They remembered him as someone who was kind, caring and full of life, bringing laughter, loyalty and warmth wherever he went.

The family also expressed their gratitude for the overwhelming support they had received since his death.

They explained that many people had wanted to honour Ross and show their support, and they wanted everyone to understand just how much he meant to those who loved him.

Their message was not only an expression of grief but also a celebration of the life he had lived.

Ross enjoyed travelling, camping and attending festivals with family and friends. He was often the person entrusted with organising their adventures, from booking accommodation to planning itineraries.

Those ordinary moments, shared experiences and future plans are now among the memories his loved ones will hold close.

A FAMILY HOPING HIS DEATH CAN SAVE OTHERS

Despite their grief, Ross’s family has chosen to speak publicly about his death for an important reason.

They hope his story will raise awareness of sudden cardiac arrest and encourage more people to consider their heart health.

“While we are yet to learn the exact cause of Ross’ death, we hope that sharing his story may raise awareness of sudden cardiac arrest,” they said.

“If raising awareness in Ross’ memory helps even one family avoid the heartbreak we are experiencing, then that will be part of his lasting legacy.”

Their words capture the devastating reality of losing a loved one unexpectedly, while expressing the hope that something meaningful might emerge from their loss.

Sudden cardiac arrest occurs when the heart abruptly stops pumping blood effectively. It is a medical emergency that requires immediate treatment. It can affect people of different ages, including those who appear physically fit.

Ross’s family has not claimed that a particular screening test would necessarily have prevented his death. Instead, they want his story to encourage greater awareness and conversations about heart health.

HE LEAVES BEHIND A DEVASTATED FAMILY AND GIRLFRIEND

Ross is survived by his parents, Mandy and Shane, his siblings, his baby nephew and his girlfriend, Katie.

For Katie, the loss is particularly heartbreaking. The pair had spent months training together, sharing the challenge of preparing for the half marathon and supporting a cause they cared about.

What should have been another milestone in their journey together has instead become an unimaginable tragedy.

His parents and siblings must now face life without a much-loved family member whose energy and warmth touched so many people.

Friends and fellow runners are also mourning a young man whose enthusiasm for sport and life made him a valued part of their community.

Run 4 Wales has confirmed that it is working with the bereavement charity 2wish to provide ongoing support to Ross’s family and friends.

Fundraising appeals have also been established in his memory, including support for cardiac screening and bereavement services.

A LIFE REMEMBERED FOR KINDNESS, NOT JUST TRAGEDY

Ross Williams-Griffiths was only 24.

He was a young man who loved sport, cherished his family, built a promising career and looked forward to the next adventure with the people closest to him.

He had trained for months for a race that was meant to help others. He had shared that journey with his girlfriend, surrounded by the encouragement of friends and family.

His death has left those who loved him with a pain that words cannot fully express.

But his family’s tribute makes one thing clear: they want Ross to be remembered for the way he lived, the kindness he showed and the happiness he brought to others.

His story is also a reminder that physical fitness does not guarantee protection against every medical emergency, and that raising awareness about heart health matters.

“If raising awareness in Ross’ memory helps even one family avoid the heartbreak we are experiencing, then that will be part of his lasting legacy.”

For Mandy, Shane, Katie and everyone who loved Ross, the road ahead will be difficult.

Yet the warmth, loyalty and enthusiasm that defined his life will remain in the memories of those he leaves behind.

Rest in peace, Ross. You were loved, and you will not be forgotten.
