Officially Amazing

Desiree Burch joins Ben Shires and Haruka Kuroda to present. British Olympian Claire O'Hara attempts a kayaking record with her husband in Sydney, Australia. And drag racer Tom Bagnall goes for glory in a go-kart - with a jet engine on the back! Also, we welcome back our Officially Competitive legends - Cherry, Ray and Steve - competing for records in front of a live audience in our secret bunker.

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.

Australia's all-time greatest record breaker tries to catch the fastest tennis ball ever, at over 200 kph. An American daredevil dunks a doughnut in a mug of coffee via a bungee jump, and Britain's best stunt car driver Alastair Moffatt, returns, aiming to drive a car on two wheels around cars driven by his entire family. In the bunker, the Officially Competitive legends attempt to become the world's fastest at running with a balloon between the knees.

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.

Featuring the return of daredevils the Bold Dogs who will somehow combine awe-inspiring motorcycle stunts with... basketball. There's also a somersaulting master of the 2wheel board from Australia and a happy couple from America will attempt a skipping record - with a spiky and painful difference. Also, in Officially Competitive, it's the first team event of the series - just who will peel and eat an orange the fastest, while blindfolded? And which one of the legends will end up in the feared Gunge Tank of Doom?

It's the return of hula-hooping legend Marawa, who attempt a record involving three hoops and a pair of roller skates. Two brave heroes from China compete to climb some stairs on their hands. And we find out if speed-skipping sensation Peter 'Skip Beatz' Thompson can top his own super-fast skipping record. Also, Sizzling Steve, Mr Cherry and US Ray will clash once more in their quest to be crowned as Officially Competitive Champion - but which one of them can balance a fidget spinner on their nose for the longest? Ben Shires, Haruka Kuroda and Desiree Burch will be on hand to find out.

Featuring a 14-year-old yo-yoing superstar, Australian professional skateboarder Nikki Rose Quinlan taking on a world record in preparation for the Olympics, and in the bunker, the Officially Competitive legends attempting to build a jelly cube pyramid using chopsticks in record speed, with mixed results. Also, in China, two challengers try to complete the world's highest wall-assisted backflip.

Featuring limbo skating from China, boomerang chucking from Australia and a talented dog called Molly with a special mystery owner.

Featuring the return of Anthony Kelly - real-life ninja and Australia's greatest ever record breaker - this time catching tennis balls at 100kmp, while blindfolded. Professional breakdancer B-Girl Roxy is head spinning. Germany's Ronnie C Rock is car spinning. And our Officially Competitive contenders take on the world's longest backwards jump.

Caspa the hurdling llama and Australian football freestyler Jed Hockin attempt to break records. And in the bunker, our Officially Competitive contenders attempt to decorate cupcakes in record time, and take on the record for backwards bum scooting.

Kayaker Claire O'Hara returns with an incredible record attempt, balloon-modelling expert Ryan Tracey makes balloon elephants without even looking and a man from China shows off his remarkable chin. Meanwhile, Officially Competitive showcases one of its toughest events yet - flipping and catching drinks coasters - with chopsticks. Will Cherry, Ray or Steve triumph? And who will be dumped into the gunge tank of doom?

The race to be crowned Officially Competitive Champion is heating up and our three heroes will attempt a vigorous aerobics record. Sizzling Steve is not the hot favourite. Also, the Hannover United wheelchair basketball team attempt to drag three trucks 100 metres, Marawa the Amazing returns for another hula-hooping record, and this time she's brought a whole troop of friends to help, and there is a tricky football record from Australia.

Record attempts from around the world. Featuring mighty stunt-driving pair Alastair and John Moffatt, who take each other on in a bid for glory, Australian pro-skater Nikki Rose Quinlan, and Mr Cherry attempts to move egg yolks with chopsticks in world record time. Also with competitive team domino toppling, and two teams from China take on a skipping challenge - while in a human pyramid.
