FIT AND HEALTHY AT JUST 24… RUNNER DIES DURING CARDIFF HALF MARATHON AS HEARTBROKEN FAMILY PAY TRIBUTE

Ross Williams-Griffiths was running alongside his girlfriend in a race to raise money for charity when tragedy struck just miles from the finish line. Now, his devastated family hopes sharing his story will help raise awareness of sudden cardiac arrest.

A 24-year-old runner who collapsed during the Cardiff Half Marathon has been remembered by his family as a kind, generous and hardworking young man whose life was filled with love, ambition and adventure.

Ross Williams-Griffiths, from Bargoed in Caerphilly, Wales, suffered a sudden cardiac arrest while taking part in the race on Sunday, October 4, 2026. Despite receiving urgent medical attention, he tragically died.

The heartbreaking news was confirmed by race organisers Run 4 Wales, with further details about Ross and his life shared publicly by his family on October 21.

His death has left his loved ones, friends and fellow runners devastated. But amid their grief, his family hopes that telling his story will help other people understand the importance of awareness surrounding sudden cardiac arrest.

 HE WAS RUNNING BESIDE HIS GIRLFRIEND WHEN TRAGEDY STRUCK

Ross had spent months preparing for the 13.1-mile half marathon, approaching the challenge with the enthusiasm and determination that characterised so much of his life.

He was running alongside his girlfriend, Katie Bowen, with the couple affectionately known as “Team Griff-Bow”.

The pair were taking on the challenge to raise money for Tenovus Cancer Care, a Welsh charity supporting people affected by cancer.

According to reports, Ross collapsed after suffering a sudden cardiac arrest approximately 12 miles into the race, leaving him only a short distance from completing the course.

Emergency medical teams responded, and he received urgent treatment before being taken for further medical care.

Tragically, the efforts to save him were unsuccessful.

For Katie, what should have been a shared sporting achievement became an unimaginable loss. The couple had been training and fundraising together, united by a cause they cared deeply about.

Ross’s death has since prompted an outpouring of sympathy from the running community and those who have learned about the young man behind the heartbreaking headlines.

“KIND, CARING AND FULL OF LIFE”

In a moving tribute released through Run 4 Wales, Ross’s family described him as someone who brought happiness and warmth wherever he went.

They said he was “kind, caring and full of life”, adding that he brought laughter, loyalty and warmth to the people around him.

His family also described him as generous and hardworking, a friendly face who never had a bad word to say about anyone.

They remembered his ability to make people feel welcome, no matter where he was or whom he was meeting.

Ross was passionate about sport and adventure. Whether playing football, golf, snowboarding, bodyboarding or preparing for his next running challenge, he approached life with enthusiasm and determination.

He was also a keen goalkeeper and had recently begun running with the South Wales Striders alongside his brother, Rhys, and Rhys’s fiancée, Jayde.

For those who knew him, Ross was far more than a runner who died during a sporting event. He was a beloved son, partner, brother and friend whose presence made a difference to the lives of the people around him.

A PROMISING FUTURE CUT SHORT

Away from sport, Ross had built a promising career with GE Aerospace.

His family said he had a bright future ahead of him, and his dedication and strong work ethic had earned him the respect and admiration of colleagues.

He loved spending time with family and friends, travelling, camping and attending festivals. He was often the person others relied on to organise adventures, from arranging accommodation to planning itineraries.

Those seemingly ordinary details now carry enormous significance for the people mourning him.

They paint a picture of a young man who loved bringing people together, making plans and creating memories with those closest to him.

At just 24, Ross had so many experiences still ahead of him. His death has left his family confronting a future that will be painfully different from the one they imagined.

HIS FAMILY HOPES HIS STORY WILL SAVE LIVES

As they grieve their loss, Ross’s family has chosen to speak publicly about what happened in the hope that their tragedy might help protect others.

They explained that, although Ross was young, active and appeared fit and healthy, they were still waiting to learn the exact cause of his death.

The family hopes that raising awareness of sudden cardiac arrest could help another family avoid experiencing the same heartbreak.

“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,” they said in their tribute.

Their message is not simply about remembering how Ross died. It is about ensuring that his life can make a difference beyond the people who knew him personally.

By sharing his story, they hope to encourage greater awareness of heart health and the importance of seeking appropriate medical advice when concerns arise.

HIS RUNNING CLUB REMEMBERS A MAN WHO ALWAYS SMILED

Ross’s death has also devastated the South Wales Striders, the running club he had recently joined with members of his family.

In a tribute shared on social media, the club remembered him as someone who always had a smile on his face and genuinely loved running.

Members said they felt grateful to have known him and described him as a pleasure to run with.

For a running community built around shared goals, encouragement and friendship, losing one of its members in such circumstances is particularly painful.

Running clubs often become places where people find companionship as well as fitness. Members train together, support one another through difficult sessions and celebrate the achievement of reaching the finish line.

Ross had become part of that community, and his absence will be felt by those who shared those experiences with him.

The club has also encouraged runners to consider heart-health screening, highlighting organisations that offer screening services to younger people.

ORGANISERS PAY TRIBUTE TO THE MEDICAL TEAMS

Run 4 Wales, the organisation behind the Cardiff Half Marathon, expressed its condolences to Ross’s family and friends.

Chief executive Matt Newman said the loss of a runner at one of the organisation’s events was felt deeply by everyone involved.

He thanked Ross’s family for sharing his story during an extremely difficult time and said the organisation’s focus remained on supporting his loved ones.

The organisers also praised the event and hospital medical teams for their rapid and professional response.

Run 4 Wales has been liaising with bereavement charity 2wish to provide ongoing support to Ross’s family and friends.

The charity supports people affected by the sudden and unexpected death of a child or young adult, helping families navigate the devastating aftermath of loss.

A REMINDER THAT HIS LEGACY IS MORE THAN THE WAY HE DIED

Ross’s family has made clear that they want people to remember the person he was, rather than allowing his final moments to define his life.

He was a young man who loved sport, embraced new challenges and enjoyed sharing adventures with the people closest to him.

He was building a career, strengthening his connections within the running community and raising money for a cause that mattered to him.

His decision to take part in the Cardiff Half Marathon was an expression of those qualities: commitment, determination and a desire to do something meaningful alongside his partner.

Now, his family hopes that the awareness raised by his death will become part of a lasting legacy.

For Katie, his parents, his brother and everyone who loved him, the pain of losing Ross cannot be undone. But they hope that sharing his story may encourage others to take heart health seriously and help prevent another family from experiencing the same devastating loss.

Ross Williams-Griffiths was just 24 years old. He had a promising career, a passion for sport and a future filled with possibilities.

His family will remember the laughter he brought, the kindness he showed and the warmth he shared with everyone around him.

And through their determination to raise awareness, they hope that even in the midst of unimaginable grief, something positive can emerge from the loss of a young man who meant so much to so many people. 💔🕊️
