BERTIE the tortoise is thought to have set a new world record today.
The young Leopard tortoise covered the 18ft uphill course at Adventure Valley, near Durham, in 21.47 seconds - around half the previous best time, set back in 1977.
Bertie then went on to beat his own time, clocking in at 19.59 seconds.
The details will now be sent to Guinness World Records for official confirmation.
