This guy ran a Sydney marathon in a suit -- and set a Guinness World Record

Matthew Whitaker, a 25-year-old Sydneysider, has just set a Guinness World Record for running a marathon in a full, three-piece suit.

Whitaker achieved the feat at the Sydney Running Festival on Sunday — a 42-kilometre race through Sydney’s CBD and outer regions.

Whitaker told Fairfax Media that he was inspired to give it a go after someone set the record for fastest marathon dressed as a jester at event the previous year.

To be eligible for the record he had to wear a vest, jacket and tie, and running shoes were allowed. His suit was one size larger so that it wasn’t too restrictive.

Here are the other rules he had to follow.

Incredibly, Whitaker finished the race in 27th position with a time of two hours, 44 minutes and 28 seconds — just over 29 minutes behind the winner, Japan’s Shota Hattori.

Here’s Whitaker during the record-breaking marathon.
