For a South African leopard tortoise, 'Bertie' is really fast.

Clocking a speed of 0.28m/s, which is twice the speed of an average tortoise, Bertie got his name into the Guinness Book of Records at the Adventure Valley family park in Durham, UK where he made the attempt.

According to a BBC report, Bertie covered 18ft in 19.59 seconds and smashed the previous record of 43.7 seconds, which was standing since 1977.

Though the record was attempted in July last year, the 10-year-old tortoise was recently inducted into the 2016 list.

Here is a look at his record attempt.
