Race Across The World star Jo Gardiner has died aged 61 following a long battle with cancer, her family has confirmed, little more than a year after the death of her son and BBC co-star Sam Gardiner.

The Manchester physiotherapist became known to millions after competing alongside Sam in the second series of the BBC travel programme in 2020. Their journey across Latin America and close mother-and-son relationship made them memorable to viewers.

Jo is survived by her other son, Charlie. Her death has prompted tributes from her family, the BBC, Studio Lambert and members of the Race Across The World community.

How did Jo Gardiner die?

Jo’s family said she died following a “long and courageous battle with cancer”. The specific type of cancer has not been publicly disclosed, nor have details about when she was diagnosed or her treatment been confirmed.

Her family remembered her as an intrepid adventurer who was brave, kind, witty and deeply loving. They encouraged people who knew her to share funny stories, have adventures, laugh loudly and live life fully in her memory.

Who was Jo Gardiner?

Jo was a physiotherapist from Manchester who found a national audience through Race Across The World.

She and Sam joined four other pairs in series two, racing from Mexico City towards Ushuaia in Argentina. Contestants had to navigate across Latin America on a restricted budget, making decisions about routes, accommodation and work along the way.

Jo wanted to undertake a major travel adventure with Sam. Their relationship became central to their story as viewers watched them deal with the pressures of travelling together.

Jo and Sam did not reach the final destination. After making substantial progress through the competition, their dwindling finances eventually left them unable to continue. Their impact on the series, however, extended well beyond their finishing position.

What happened to Jo Gardiner’s son Sam?

Sam Gardiner died aged 24 in 2025 following a car crash in Greater Manchester.

His white Volkswagen Golf R estate left the road and rolled before coming to rest on its side. Sam was taken to hospital but later died from his injuries.

Sam worked as a landscape gardener and had been working on an isolated estate on Scotland’s west coast. He had returned to the Manchester area for a family gathering.

His death was particularly painful for viewers who remembered watching him travel alongside Jo. The BBC programme subsequently paid tribute to him.

Race Across The World pays tribute to Jo

Studio Lambert, the BBC and the wider Race Across The World cast offered their sympathies to Charlie and Jo’s family and friends.

The programme remembered Jo’s passion for life, kindness, strength and devotion to her family. It also recalled Sam describing his mother as “amazing” during filming.

Jo was described as the matriarch of the Race Across The World cast family, reflecting the relationships she maintained beyond her appearance on television.

The response shows why contestants can remain familiar to audiences long after a reality programme ends. A similar connection between viewers and television personalities has shaped interest in the death of The Voice UK singer Dean Franklin following a cancer diagnosis.

Jo Gardiner’s work with Diabetes UK

Jo also lived with type 1 diabetes and was an ambassador for Diabetes UK, giving her public story another dimension beyond television.

Her family has established a JustGiving fundraising page in her memory, with donations supporting Diabetes UK.

That advocacy reflected Jo’s willingness to use her own experience to help others living with diabetes, while her television appearance highlighted her enthusiasm for travel and adventure.

Why Jo and Sam’s story is being remembered

Race Across The World is built around both travel and relationships, and Jo and Sam became an example of how those two elements can intersect. Viewers watched them experience unfamiliar places while navigating the challenges of travelling as mother and son.

Their story has taken on greater poignancy following their deaths within a relatively short period. Jo’s family has nevertheless focused its tribute on how she lived rather than solely on the circumstances of her death.

That emphasis on adventure and resilience echoes other stories about people pushing themselves beyond familiar boundaries, including Laura Baillie’s completion of all 1,072 peaks in the Full House climbing challenge.

For people searching for more information following Jo’s death, the key point is that her family has confirmed a long cancer battle but has not revealed what type of cancer she had. They have asked for privacy while encouraging those who loved her to remember her through laughter, friendship and adventure.
