A pair of intrepid runners have pushed themselves beyond the limit of human performance to simultaneously break a coveted endurance world record
John Stocker and Matt Blackburn achieved the Herculean feat during an event at Knettishall Heath, on the Suffolk-Norfolk border.
They had begun competing at lunchtime on Saturday (June 5) in the Suffolk edition of Back Yard Ultra, which challenges participants to repeatedly run a 4.167-mile trail route.
Those taking part have one hour to complete each loop and must be back in time to start the next - or they are knocked out.
The race continues until only one person is left competing.

There will not be an official winner of the event until one of the two fails to complete a solo lap within the hour.
