Kiwi lands world first BMX quadruple backflip

Kiwi BMX rider Jed Mildon has become the first person in the world to execute a quadruple backflip.

The Taupo extreme sport athlete has spent the last nine months along with Nitro Circus teammate James Foster to land the milestone trick.

Mildon finally pulled it off at Travis Pastrana's "Pastranaland" complex in Maryland, USA.

"This is the pinnacle of my life. Kinda like a story that you want growing up as a child but you don't know how it's going to pan out. It's unreal," Mildon said.

"To finally stomp the quad and reach my goal is unbelievable. I'm so pumped," 27 year old Mildon said. "It wouldn't have been possible without the support of my family, including my Nitro Circus mates. James Foster is such an incredible athlete and a great friend. He pushed me to challenge myself and test my limits."

Mildon was the first person to ever do a triple backflip on a BMX bike (2011), the YouTube video showing his daredevil feat has over 10 million views.

Foster is the only other rider who has landed a triple, and he is the only one performing the trick regularly. Foster's triple flips are now a highlight of Nitro Circus Live shows around the world.

"While we competed hard and neither one of us wanted to come in second, I am definitely happy for Jed. I know what he's had to go through over the course of this," Foster said.

"Now I'm looking forward to getting back out on the road and finding the next challenge."

The challenge was filmed for US television network NBC's "Revolution Day: The Chase for the Biggest Trick in Action Sports History", which chronicled the nine-month journey of Foster and Mildon as they raced to reach a milestone few thought attainable.

Jed landed the flip on 2 May but it was a closely guarded secret until the NBC aired the challenge today.
