We’re thrilled to announce that our team of 26 swimmers completed the 2-mile swimming challenge from Alcatraz Prison to Crissy Field Beach on 19th May 2025. Conditions were challenging, but our incredible swimmers bravely took on the cold, choppy waters and strong underwater currents of San Francisco Bay to raise a mind-blowing £75,000 to date for Velindre Cancer Charity.
Swimming from Alcatraz is one of the most famous open water swims in the world. The magnificent backdrop of the iconic Gold Gate Bridge and the dramatic skyline of San Francisco make for an unforgettable experience. Organised by Odyssey Open Water Swimming and led by Charity ambassador, Dave Tonge, the team were well looked after from start to finish—even having their own air steward, Velindre fundraiser Angie Walsh , taking care of them on the flight over and cheering them on during the swim. Velindre ambassadors, Wayne and Jayne Griffiths, also kindly donated guardian angel keyrings for the whole team, in memory of their daughter Rhian Griffiths, and to wish the team good luck for the event.
It was said that no prisoners who escaped Alcatraz ever made it to freedom, lost to the punishing waters and dangerous wildlife of the Bay. But Velindre’s swimmers, despite being joined in the water by sea lions and even the odd whale, made it to shore in one piece and celebrated their achievement with a well-deserved, post-swim meal together.
Each swimmer has a special connection with Velindre and has overcome their own personal challenges to take part in this incredible challenge.
One swimmer, Lea Craven, who was treated at Velindre as a child and again later in life, said of her motivations for fundraising: “Velindre Cancer Centre was my lifeline through childhood cancer. Since then, I’ve faced multiple health challenges, but Velindre’s legacy of care has stayed with me. Now, I want to give back.”
Two other swimmers, Rebecca John and Rhi Thomas both celebrated their 2-year anniversary of finishing treatment whilst on the swim, with Rebecca saying: “I literally owe my life to Velindre and Llandough. Not only did they provide the medical care I needed, but [Velindre provided] psychology, resources for my children, reflexology and unwavering support whenever I have needed it.”
Another swimmer, Andrew Davies, who is still in active treatment, used the swim as an opportunity to give back to Velindre for the care he is receiving and to achieve a special personal milestone—a true testament to his determination and spirt.
The group’s leader, Dave Tonge, reflected on his motivations for leading the swim, saying:
“I’m so proud to be part of team Velindre and to lead the first ever overseas open water swim. Most swimmers I know have their sights on it as it’s such an iconic and world-renowned swim – it’s certainly one to show off about once you complete it! Velindre is very close to mine and my family’s hearts as several of them have had treatment there.”
Velindre’s swimmers have spent the past year tirelessly training for this swim of a lifetime and Velindre Cancer Charity is incredibly proud and thankful for their bravery, commitment and support.
The Charity extends a truly heartfelt thank you and congratulations to each swimmer who completed the extraordinary Alcatraz swim—the funds raised will make a life-changing difference to Velindre’s patients and families in South East Wales and beyond.
