On 17 March 2022, British and Irish national Mark O’Brien’s world changed dramatically with just three letters. But after months of decline he came back with a plan that surprised the medical and sporting communities: on 24 September 2023 he set a Guinness World Record for the longest open swim non-stop, unaided ALS survivor. 11 km was swum in 5 h 23 min. He swam the last 1.5 km with his three children. Mark’s achievement was covered by the media, including the BBC, and raised £25,000 for the MND Association (note 1).
To date,, he is still in the midst of disease progression. However, he is taking on his next challenge, and Mark believes he can help by working hard to increase people’s understanding of the disease and getting their support.
Soon, he will be taking on his challenge to set two Guinness World Records in one day on 1 September 2024.
