Neil Gilson, a 40-year-old hotelier from Ilfracombe, Devon, has become the first person to swim across the ten largest lakes in Switzerland. Over the course of two years, Gilson completed a grueling 233-mile swimming challenge, culminating in a final 22-hour swim covering the 45-mile length of Lake Geneva.

The project required Gilson to endure extreme physical demands, including cold water temperatures and prolonged periods of exertion. He was required to swim continuously without touching his support boat, which provided nourishment and hydration via a pole throughout the swims. In total, Gilson spent approximately 110 hours swimming during the challenge.

Reflecting on the accomplishment, Gilson acknowledged the physical toll, describing himself as “a bit broken” with sore muscles but expressed satisfaction at completing the endeavor.

The challenge also had a charitable purpose, raising funds for several organizations including Pans Pandas UK. This charity supports individuals affected by Pediatric Acute-onset Neuropsychiatric Syndrome (PANS) and Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal infections (PANDAS), conditions that can cause sudden and severe changes in behaviour. Gilson’s motivation was personal, as his son Jack has been diagnosed with the rare disorder and has since shown considerable improvement.

Gilson’s achievement marks a significant milestone in endurance swimming, combining remarkable physical resilience with a commitment to raising awareness and support for a rare medical condition.
