British open-water swimmer Neil Gilson has completed an extraordinary endurance challenge by swimming across Switzerland’s 10 largest lakes, covering a combined distance of 233 miles (375 km) over two years. The achievement is now awaiting verification by World Records as a potential world first.
Gilson, from Ilfracombe, Devon, completed the ambitious challenge with a gruelling swim across Lake Geneva, spending just over 22 hours in the water before reaching the finish. The final crossing pushed Gilson to his physical and mental limits. He endured approximately 10 hours of darkness, fatigue and considerable physical discomfort during the swim.
After completing the challenge, Gilson said he felt physically battered but extremely pleased to have achieved his goal. Strict open-water swimming rules were followed throughout the challenge. Food and drinks were passed to him using a cup suspended from a pole, while he was prohibited from touching the support boat during the swims. The finish became particularly memorable when his children joined him as he crossed the line at Lake Geneva.
Gilson’s ambitious journey took approximately two years to complete, with the 10 lake crossings covering a combined 233 miles (375 km). Not everything went according to plan. During the challenge, Gilson faced extreme exhaustion and even recalled a moment when he fell asleep in the water. Knowing that around 25 friends and family members would be waiting for him at the Lake Geneva finish helped motivate him through the difficult final stages.
Beyond the sporting achievement, Gilson undertook the challenge to raise funds and awareness for PANS PANDAS UK, after one of his children was affected by PANS/PANDAS, a paediatric autoimmune condition. He also raised money for The Brain Charity, adding a charitable purpose to the endurance challenge.
The Lake Geneva Swimming Association observed and piloted all 10 swims, helping ensure the crossings were conducted according to the required rules. The achievement will now be submitted for World Records verification to determine whether Gilson has officially accomplished a world-first feat by swimming Switzerland’s 10 largest lakes. If verified, the accomplishment will mark the culmination of an exceptional two-year journey combining endurance, determination and charitable fundraising.
