Dirk Auer already holds the world speed record for inline skating but that just wasn’t enough for this dare devil.

Auer specially designed a pair of inline skates that would allow him to safely skate down a roller coaster at tops speeds.

The Mammoth roller coaster at the Trips Drill theme park in Stuttgart is where this extreme stunt took place after total of 2 months planning. Dirk Auer succeeded and reached 56mph in his minute long journey.
