PictoVista: Guinness World Records' Bonkers Sporting Champions

Guinness World Records, the global authority on record-breaking achievement, has unveiled a selection of the wackiest feats ever achieved in the world of alternative sport in a new book.

Some will make you marvel, others will have you gasping with astonishment and one or two could make you feel slightly nauseous.

The unique athletes who have taken record-breaking to new and outrageous extremes have been honoured in the new Guinness World Records e-book, Totally Bonkers Sporting Champions, which is available on iPad, nook and kindle.

They include New Zealand’s Veronica Torr who recorded the Fastest 100 Metre Hurdles Wearing Swim Fins - in 18.52 seconds - and Kenichi Ito, from Japan, who ran the Fastest 100m Running on All Fours in 18.58 seconds.
