HE DID WHAT?! ON ROLLER SKATES?

An adrenaline junkie has taken inline skating to new heights and set a new world record after racing down a roller coaster at speeds of up to 60mph.

'If the skates were to catch a stray nail then I could have fallen and I would almost certainly have died.'

The 36-year-old admitted he had placed his life at risk by performing the daredevil stunt. 'This was a very dangerous stunt because there were so many factors to consider,' he said. 'The roller coaster is wooden and so unlike rides made from iron and steel there was always a chance of the odd nail or screw that would not be entirely flat. Traveling at speeds up to 60mph, Auer skated the entire length of the roller coaster - 860 meter in just over a minute.

Spending two months planning the outrageous stunt, Mr. Auer also designed and made the monster skates, which took him a total of 110 hours' work.

But he said there was no room for error and he used 16 rolls on each shoe.

'After this some of the sides were so high that at times I was at 90 degrees and so it was very important to have as much traction as possible. Luckily everything went according to plan - it was a lot of fun.'

Mr. Auer, from Gross-Gerau near Frankfurt, is considered to be the most extreme in-line skater in the world. He already holds the world record for reaching speeds of 190mph as he was dragged along behind a Porsche GT2.
