A former soldier attempting to run the distance of 100 marathons in 100 days smashed the current world record today - but is still only halfway through his challenge.
Mike Buss, 36, has been running on treadmills at various locations around the country since June 16 as part of his Hero 100 Challenge.
He aims to raise £100,000 for the Help for Heroes charity by the end of the year.
Speaking as he ran his 51st marathon at McArthur Glen Designer Outlet shopping centre in Ashford, Kent, he said: "This is an enormous challenge for me but one that I am enjoying nearly every minute of.
"I would like to thank Chrysler for all their support since I started my campaign to become the world's fittest man.
"The Hero 100 challenge will not only help me set a new world record but more importantly it will raise vital funds for Help for Heroes."
Buss, from Swindon, Wiltshire, served in Northern Ireland during his 10 years in the Army, and has now devoted his life to breaking as many records as he can to raise money for military charities such as Help for Heroes.
He plans to complete his treadmill challenge at the Leisure Industry Week at the NEC Birmingham on September 23.
