Watch: Brisk Bertie, the world's fastest running tortoise

London: The tortoise, Brisk Bertie, has officially become the world record breaker recently by travelling 18ft at a 19.59 seconds jaw-dropping pace.

Bertie has beaten the time held by Charlie over 37 years ago, the Daily Star reported.

Marco Calzini, director of Adventure Valley where Bertie lives, said that the original record was set in 1977 which was 43.7 seconds so Bertie has definitely smashed the record.

Birtie has now just to pass the drug test.
