Bertie, a tortoise living in Brasside, England, holds the record as quickest in the world after traveling at speeds of 0.62 mph.
The reptile completed a 18-foot course with a time of 19.53 seconds.
"I used to collect the Guinness World Records books -- my first was the 1980 edition -- and I fondly remember seeing them all in the shops. To be in the book is a dream come true, a massive achievement!" Bertie´s proud owner says.
