The longest marathon on a fairground/theme park attraction is 48 hours 8 minutes and 25 seconds riding a ferris wheel, achieved by Clinton Shepherd (USA) at Navy Pier in Chicago, Illinois, USA, on 19 May 2013.

Shepherd is a Navy Pier employee, and rode in a custom decorated gondola with curtains, a Tiffany chandelier, flat screen TV, and Xbox. During the overnight periods he played “Call of Duty: Black Ops II” with friends at home via a wireless internet connection.
