Ross Edgley
Ross Edgley is a British athlete, ultra-marathon sea swimmer and author. He holds multiple world records, but is perhaps most recognised for completing the World's Longest Staged Sea Swim in 2018, when he became the first person in history to swim around Great Britain, in 157 days In 2024, he also became the first person in history to simultaneously hold official Guinness World Records for long-distance swimming in the sea and river when he broke the record for the longest non-stop, continuous river swim down the Yukon River.
Globally recognised for undertaking athletic adventures in the most hostile conditions for conservation charities, Edgley has completed swims with white sharks in Australia, tiger sharks in the Bahamas and bears in the Yukon River. He also swam through the Gulf of Corryvreckan one of the world's largest whirlpools and crossed frozen fjords in the arctic circle where the water temperature was just above freezing and documented his training, nutrition, theories and strategies and published them in his books titled The World's Fittest Book, The Art of Resilience, and Blueprint: Build a Bulletproof Body for Extreme Adventure in 365 Days. All of which became No.1 Sunday Times Bestsellers and have been translated into several other languages.
Background
Edgley was born into a sporting family in Grantham, Lincolnshire. His father was a tennis coach and his mother was a sprinter. Although playing many sports as a child, he specialised in swimming and water polo and represented his country internationally at junior level whilst studying at The King's School, Grantham.He later gained a sports scholarship to study at Loughborough University's School of Sport and Exercise Science, where he continued to train at the British Swimming National Centre. A year into his scholarship, Edgley then retired from international competition and decided to transition into ultra-distance sea swimming instead, which the university supported through the National Centre for Sport and Exercise Medicine.
In 2019, he received an honorary doctorate from Bishop Grosseteste University in Lincoln, for his research into mental and physical resilience and continues to coach and lecture around the world in the science and psychology of adventure.
Swimming records
The Great British Swim (2018)
Between June and November 2018, Edgley completed a 157-day swim around Britain. Aided by a team of experts which monitored the tides and his health in his support boat Hecate, he typically swam for six hours, rested for six hours, and then swam for another six hours on repeat. He typically consumed around 15,000 calories a day.The gruelling swim took its toll on his body, disintegrating his tongue through the eroding effect of the salt, giving him "Rhino Neck" from the effect of the wetsuit rubbing, and his feet entirely losing their arches and turning a deep purple and yellow. The team treated him with Sudocrem, Vaseline, plasters, bin bags and duct tape. Edgley's journey was documented as a weekly internet series, "Ross Edgley's Great British Swim", produced by Red Bull TV.
After completing the swim in Margate on 4 November 2018, the World Open Water Swimming Association announced it as the World Swim of the Year 2018 and it became officially recognised as "The World's Longest Staged Sea Swim." Talking about his historic swim Edgley said, "It's my hope that people remember the Great British Swim as an example or experiment in both mental and physical fortitude."
Length of the English Channel (2018)
During his circumnavigation swim of Great Britain, Edgley also broke several other records. Notably this involved becoming the first person to swim the length of the English Channel from Dover to Land's End, over 350 miles in 30 days. Edgley never celebrated the achievement, however, and instead joked it was only a "warm up" because he still had 1,442 miles to swim before he completed his much larger mission and arrived back in Margate, Kent.Land's End to John o' Groats (2018)
Edgley also accidentally became the fastest person to swim the from Land's End to John o' Groats in 62 days. More than halving the time of the previous record, Edgley and his crew said they did not realise they had broken another record and were just trying to swim fast enough to avoid an Arctic storm approaching from Iceland. He then became the first person to swim the length of the Moray Firth, before heading to the English border at Berwick-upon-Tweed where he joked, "It was all downhill from here".Loch Ness, Scotland (2022)
On 23 September 2022, Edgley undertook a charity swim in Loch Ness, Scotland. Known for being the largest lake in the UK, the water temperature rarely reaches above 5°C. Which is why, in preparation for the extreme endurance event and to counteract the cold effect of continual immersion in water, he gained 10 kilos of weight by consuming 10,000 calories a day. After 52 hours and 39 minutes he was forced to end his swim early, due to the onset of cellulitis and hypothermia and was taken to hospital. The swim was done in support of Parley for the Oceans, and was not observed by any swimming authority. The route and precise distance are unknown, but Ross remains the only person to survive swimming in a wetsuit in the cold waters of Loch Ness for more than 52 hours.Lake Trasimeno, Italy (2023)
On 13 July 2023, Edgley was scheduled to attempt another ultra-marathon charity swim in Lake Trasimeno, Italy. During this time the Italian Meteorological Society warned of a deadly heatwave hitting the area where temperatures exceeded 45°C. Dubbed the 'Cerberus heat wave' after the mythical monster that guards the gates of hell the World Meteorological Organisation later confirmed this was the hottest month ever recorded on earth. This caused the water temperature to rise above 34°C which the Federation Internationale De Natation states is unsafe for ultra-marathon swims due to heat stroke since the maximum temperature of water for FINA-sanctioned open water swimming competitions is 31°C. This rule follows a study carried out by the University of Otago in New Zealand that was conducted in collaboration with FINA, the International Olympic Committee and the International Triathlon Union today. Despite the warnings, Edgley still wanted to attempt the swim for his charity partners. After 32 hours and he was pulled out the water due to heat stroke and hyperthermia.Yukon River, Canada (2024)
Between 16 and 18 June 2024, Edgley set a new official Guinness World Record for his 510km non-stop swim down the Yukon River in Canada. Swimming between Whitehorse and Dawson City, Edgley was not permitted to stop, sleep or touch the boat as per the rules set by WOWSA. The lowest water temperature recorded was 8°C, which is why to counteract the cold effect of continual immersion in water, he gained 15 kilos of weight by consuming 20,000 calories a day. In addition to the threat of hypothermia, Edgley had to navigate white water rapids, bears and wolves.Iceland Swim (2025)
Between 17th May and 8th September Edgley set a new record becoming the first person to swim around Iceland after completing a 1,000-mile journey.Other athletic achievements
On 22 January 2016, Edgley began a marathon around the Silverstone circuit in Northamptonshire, pulling a car. The event was dubbed "The World's Strongest Marathon". As part of his training for the event, he went on a special 6,000 calorie plus daily diet and had already done a pull with the Mini during training. He completed the marathon endeavor to raise money for the Teenage Cancer Trust, Children With Cancer, Sports Aid and United Through Sport.A few months later, on 22 April 2016, Edgley also began his "World’s Longest Rope Climb" conquest at Pippingford Park in the Ashdown Forest of Sussex, in which he completed a rope climb of, the exact height of Mount Everest, in 19 hours and 54 minutes. The money raised went to the Teenage Cancer Trust.
Other feats to raise money for charity include a barefoot run in a month carrying a backpack, an Olympic Distance Triathlon carrying a tree, swimming over across the Caribbean Sea pulling a tree, swimming non-stop for 48 hours at the Commando Training Centre for the Royal Marines, and completing 30 marathons in 30 days.
