23-yr-old US man with no legs breaks world record for fastest 20m on hands

A 23-year-old differently-abled US athlete achieved the world record for the fastest 20-metre-walk on his hands, the Guinness World Records said.

Zion Clark, who was born without legs due to a rare condition that causes abnormal development of the lower end of the spine, has set a new record by walking 20 metres in 4.78 seconds.
