Insane. That’s exactly what you’d have to be to ride a wooden roller coaster in a pair of custom made inline skates. And that is exactly what Dirk Auer is, totally insane. The 36-year old dare devil, adrenaline junkie spent 110 hours building the 16 wheeled inline skates that enabled him to reach a top speed of 56mph. As a result the 2,822 foot track, called the Mammoth roller coaster at the Trips Drill theme park in Stuttgart, Germany was completed in just over a minute.
Of note, Auer currently holds the inline skate speed record of 192mph while being dragged by a Porsche GT2.
