Friends Marcus Green, 33, and Phil Rossall, 66, overcame the odds to set a new world record for a half marathon wheelchair push.
After a patient wait for it to become official, they have now received their verification from Guinness World Records.
The pair completed the race in an amazing one hour 29 minutes 38 seconds, six minutes faster than the existing record.
Phil, formerly head of modern languages at Darrick Wood School and head of German at Langley Park School for Boys, Beckenham, was diagnosed with motor neurone disease three years ago.
At the time he was expected to live only one or two years.
Since then, he has raised over £28,000 for the Motor Neurone Disease Association.
He is totally reliant on a ventilator for breathing and has now lost the use of his muscles.
Marcus had to brave the rain and strong winds to push Phil for 13.1 miles.
