Bertie the tortoise was up to speed when he attempted to win the title of Fastest tortoise in the world. At his home in Adventure Valley, a family adventure park in Brasside, County Durham, Bertie "sprinted" on a specially designed race track in his enclosure, clocking a speed of 0.28m/s (0.92 ft/s).

With this breathtaking speed he smashed Charlie's (UK) previous record of 0.125 m/s which had been unchallenged since 1977. Since achieving his Guinness World Records title, Bertie has become a local celebrity at Adventure Valley.
