Multiple sclerosis is an auto-immune condition, external that affects the body’s central nervous system, causing a range of symptoms including blurred vision and problems with movement and thinking.
More than 150,000 people in the UK have MS.
White told the BBC he suffers with extreme fatigue, numbness and balances issues as a result of the disease.
Immediately after his diagnosis, White was told to “avoid intense exercise” and he put on three stones (19kg) in weight in the two years that followed.
He started running in 2024 after “listening to an interview on the radio about someone with MS doing a half marathon” and has since completed more than 15 half marathons.
The race covers 13.1 miles (21.1 km).
At the end of 2025, his partner suggested he try to break the world record for the fastest half marathon run by a person with MS, as his personal best at the time was only six minutes slower.
White self-isolated for two weeks before the race to ensure he did not pick up an illness, as his immune system was “deficient” due to his MS.
After finding out he had broken the record, White said he was “stunned” and “felt very proud”.
The world record will now be confirmed by Guinness World Records and is pending official certification.
