Dangerous Stunt - Skating Down the Roller Coaster

I Don't know what this man thinking of?? how can he do that?? that was really dangerous act.. so all i have to think is "Don"t try that at Roller Coaster"

German daredevil Dirk Auer established a new world record when he raced down a 860-meter wood roller coaster track in under a minute. He maintained an average speed of 56 mph on custom skates that he built himself:

‘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.
