HEARTBREAKING TRIBUTE TO ROSS WILLIAMS-GRIFFITH, 24, AFTER HE COLLAPSED DURING CARDIFF HALF MARATHON

A young runner described as fit, healthy and full of life passed away after suffering a sudden cardiac arrest during a half marathon. Now, his heartbroken family is sharing the memories that made him so special — and hopes his story could help other families.

A family in Wales is mourning the loss of Ross Williams-Griffith, a 24-year-old who passed away after collapsing during the Cardiff Half Marathon on Sunday, October 4, 2026.

Ross, from Bargoed in Caerphilly, was taking part in the 13.1-mile event alongside his girlfriend, Katie Bowen. The couple had spent months preparing for the challenge and were running together to raise money for Tenovus Cancer Care, a Welsh charity supporting people affected by cancer.

Around 12 miles into the race, Ross suffered a sudden cardiac arrest. Despite receiving urgent medical attention, he could not be saved.

His passing has left his family, girlfriend, friends and fellow runners devastated. In the days since the tragedy, tributes have highlighted not only his love of sport but also the warmth, generosity and enthusiasm he brought to everyday life.

A YOUNG MAN WHO BROUGHT LAUGHTER AND WARMTH TO OTHERS

In a tribute shared through race organiser Run 4 Wales, Ross’s family described him as kind, caring and full of life.

They said he brought laughter, loyalty and warmth wherever he went, adding that he had a unique ability to make people feel welcome.

Ross approached life with enthusiasm and determination. His interests included football, golf, snowboarding, bodyboarding and running — activities that reflected his energetic personality and love of new challenges.

He was also a keen goalkeeper and had recently started attending running-club sessions alongside his brother, Rhys, and Rhys’s fiancée, Jayde.

To those who knew him, Ross was more than a talented sportsman. He was a loyal friend, a much-loved family member and someone whose presence made a difference to the people around him.

RUNNING THE RACE WITH HIS GIRLFRIEND FOR CHARITY

The Cardiff Half Marathon was a challenge Ross had prepared for with commitment and care.

He and Katie were affectionately known as “Team Griff-Bow” and had trained together for months ahead of the event. Their participation was also intended to raise money for Tenovus Cancer Care, giving their sporting challenge a charitable purpose.

What should have been a day of determination and achievement instead became a devastating experience for everyone who loved Ross.

His family have since expressed their gratitude for the kindness and support they have received from friends, colleagues and members of the running community.

Their words have also highlighted the importance of remembering Ross for the life he lived, the people he loved and the experiences he shared with those closest to him.

A PROMISING CAREER AND A LOVE OF ADVENTURE

Away from sport, Ross had been building a promising career at GE Aerospace.

His family said he was hardworking and dedicated, qualities that earned him the respect and admiration of colleagues.

He also loved travelling, camping and attending festivals with family and friends. According to local reporting, he was often the person who organised trips, booked accommodation and planned itineraries, helping turn ideas into memorable experiences.

These details have offered a glimpse into the young man behind the headlines: someone who enjoyed bringing people together and making the most of the time he spent with them.

For his loved ones, those ordinary moments — planning an adventure, sharing a laugh or preparing for a race — are now treasured memories.

HIS FAMILY HOPES HIS STORY WILL RAISE AWARENESS

Alongside their grief, Ross’s family have expressed a hope that sharing his story could help raise awareness of sudden cardiac arrest.

They emphasised that, despite Ross being described as fit and healthy, the exact cause of his passing had not yet been established.

Sudden cardiac arrest occurs when the heart unexpectedly stops pumping blood effectively. It is a medical emergency requiring immediate intervention. It is important to distinguish this from determining the underlying reason for an individual person’s collapse, which may require further medical investigation.

The family hopes that greater awareness could encourage people to learn about cardiac health and seek appropriate medical advice when concerned.

They have also expressed gratitude to the medical teams who responded during the race and at the hospital.

Run 4 Wales chief executive Matt Newman paid tribute to Ross and offered condolences to his family and friends. He also praised the event and hospital medical teams for their swift and professional response.

TRIBUTES AND FUNDRAISING IN ROSS’S MEMORY

Ross’s passing has prompted an outpouring of support from people who knew him through his family, work and running community.

His family have shared information about fundraising efforts in his memory, including an appeal to support cardiac screening and a separate appeal connected with the bereavement charity 2wish.

The initiatives reflect their wish to create something positive from an experience that has brought such profound sadness.

For those who ran alongside Ross, worked with him or shared adventures with him, the memories remain a reminder of how much one person can mean to so many others.

“FULL OF LIFE”: A LEGACY OF KINDNESS

The loss of a young person can leave loved ones facing questions and emotions that are difficult to put into words. For Ross’s family, the pain is made especially difficult by the fact that he had been preparing for a challenge he loved and supporting a cause close to his heart.

Yet their tribute has focused on the qualities they want people to remember: his kindness, loyalty, hard work and ability to bring happiness to others.

Ross’s story has also touched the wider running community, where people come together to challenge themselves, support charities and encourage one another.

As his family navigates life without him, they hope the support they have received and the awareness raised in his memory will help honour the person he was.

Ross Williams-Griffith was just 24, with a promising career, a love of sport and many plans ahead of him. His family’s message is a reminder to remember not only the tragedy of his passing, but also the warmth, generosity and joy he brought into the lives of those around him.
