The Officially Competitive heroes are engaged in a sparkly contest to move glitter with a teaspoon, then later one of them faces a trek to the gruesome Gunge Tank of Doom. Also, a flying quad bike from America, multi-medal-winning Olympic gymnast Becky Downie defies belief on a balance beam and two monster trucks rampage around a field in Australia - on two wheels.

Featuring a daredevil resisting the power of a jet engine stream, Olympian Ashley McKenzie throwing his brother-in-law in a Judo record, and a pirouetting poodle! Also, Mr Cherry, US-Ray and Sizzling Steve take on a fiendishly tricky burpee record, with a hilarious outcome, and one of them faces a gunging.
