Dirk Auer decided to go where no sane man or woman had gone before and skated down an 860 metre track in just over a minute.
Wearing specially designed in-line skates, the German made the attempt on the Mammoth roller coaster at the Trips Drill theme park in Stuttgart.
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.
‘If the skates were to catch a stray nail then I could have fallen and I would almost certainly have died.’
‘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.
