Speed With Guy Martin

Guy takes his battered Transit van to the USA to enter the fastest road race on the planet: the Nevada Open Road Challenge.

Guy attempts to become the first person to cross the English Channel in a human-powered airship, pedaling a bike suspended from a helium-filled balloon as big as a bus.

Guy attempts to beat the speed record for a human-powered boat, with help from Olympic legends Sir Chris Hoy and Sir Ben Ainslie.
