A reporter's attempt at eating a 1kg doughnut

A Christchurch bakery is offering up free doughnuts for its customers - but there's a catch.

The policy is you have to eat the giant 1kg sweet treat in under a hour - or you have to pay the full $20 asking price. 

Get Baked has been running the competition since October last year. For $20, if you can eat the doughnut in under a hour you get a refund. 

Only a select few have been able to complete the challenge, scoring themselves a spot on the bakery's wall of fame. 

We sent Newshub reporter Megan Sutherland to see if she too could become a doughnut-eating champion.

Watch the video above for the full attempt at the challenge and to see if you think you could complete it yourself.
