Staying on in Spain also meant Mildon was well-placed to get to some of his other upcoming commitments in Europe. He went to a competition in Spain where he picked up a second, a third and a seventh placing. He also performed at another big show, the Finist Air Show in Finistere, France, gaining a first-equal at a competition afterwards for his double back flip.
Mildon's next event is in Auckland next weekend where he will be appearing at the Big Boys' Toys show before he heads to Australia for a BMX event in honour of his friend the late Dane Searl.
Mildon's triple back flip record has made him well-known in BMX circles - the YouTube clip of his world record has attracted more than nine million views so far - and it's opened up plenty of doors for him since.
"I've had a lot more time to focus on more goals which is wicked and get a lot more recognition. I'm able to enter pretty much whichever competition I like, and I got to ride the X Games in Los Angeles which was a childhood dream, it's the pinnacle of the sport."
Mildon earns his living through sponsorship, competition prize money and performing at shows.
His sponsors are Gold Coast-based clothing company Unit Technologies, which supported him in his triple flip bid, and Skinny Mobile. Although he's based in Taupo, he spends most of his time travelling.
"It's great that you get to see a lot of things, but it can be kind of lonely sometimes until you get to see familiar people or people you can relate with."
Mildon, who is of Ngati Kahungunu descent on his father's side, says there were always bikes around the neighbourhood when he was a kid growing up in Rangatira Park. He had a BMX, which he used to get from A to B and jump off kerbs.
One day he went to an event in Hamilton where famous skateboarder Tony Hawk was the drawcard. However, Mildon was much more impressed by a bunch of BMX riders he saw doing tricks out of the back of the show.
"It just blew me away."
Mildon began riding regularly at Taupo Skate Park, where he met other riders, some of whom were good enough to be sponsored.
"I grew up riding around them and they were always pushing and helping and encouraging and guiding. It [BMX] is like one big family - you can go anywhere in the world, not know anybody and turn up at the skate park and be taken in."
At present Mildon's working with Taupo district councillor Keith Crate to try to bring an international BMX jumps event to Taupo in 2013 or 2014. He envisages it comprising three events in a row - the Mega Box Worlds with the biggest set of box jumps in the world; the Dane Searl Dirt Jump Jam with the biggest set of dirt jumps in the world and the Taupo Skate Park Jam.
If he can pull it off, Mildon hopes to attract riders from around the world.
"I think I can put it on - I've worked it all out and it shouldn't cost much really," says Mildon. "The initial cost will be in the first year, but if you can get the land to do it all, then in future years I'll just be patching things up if it's permanent."
