“This is the toughest challenge I’ve ever taken on,” says Neil. “I’ve never done more than one major swim a year because of the physical and mental toll. Now, I’m aiming to swim the 10 largest lakes in Switzerland; 369km over two years.” Neil Gilson
A British father is set to swim the ten largest lakes in Switzerland, including an attempt to break his own world-record at Lac Leman, to raise awareness of a devastating childhood neurological condition that changed his son's life at just two years old.
Neil Gilson, 40, from North Devon, was once ranked second in Britain for the 1500m freestyle. A seasoned open water endurance swimmer, he made headlines after completing a 22-hour, 9-minute, 72km world-record swim across Lac Leman in July 2024. Now, he's taking on an even bigger feat: swimming ten "great Swiss lakes" over the next two years to raise funds and awareness for The Brain Charity and the Pans Pandas UK; the latter of which he has already raised £17,920.75 for through past fundraising efforts.
"It happened almost overnight," Neil said. "He went from a happy toddler to someone we couldn't recognise. We saw countless doctors and got nowhere. I felt helpless."
The challenge is deeply personal. Neil's son, Jack, now nine, was just two when he suddenly developed obsessive-compulsive behaviours, aggression, and regression following repeated infections. Jack was later diagnosed with PANDAS. PANDAS is a rare disorder, where a misdirected immune response mistakenly attacks the brain following common infections like strep throat or tonsillitis.
"Swimming is what I know, and I want to use it to bring visibility to a condition that's still so misunderstood."

“Neil’s incredible challenge is testament to his love of his son Jack and his experience of the devastating impact neurological conditions can have.
