A man who was diagnosed with Motor Neurone Disease (MND) last year has completed a world record attempt with a five-and-a-half hour open water swim.
Mark O’Brien, from Slip End in Bedfordshire, set out to achieve the longest unaided open water swim for a person living with MND.
The 54-year-old beat his own target of 6.5 miles (10.5km) at Denham water ski club in Hertfordshire.
The event will have to be verified by Guinness World Records.
