( CNN ) -- Its claim to fame has been contested , it 's been hit by tragedy and it 's been photographed by tourists from around the world . But locals still hold firm to their conviction that Baldwin Street in Dunedin , New Zealand , holds the Guinness World Record for being the steepest street in the world , with a 38 % grade at its steepest section . Various sources list Canton Avenue in Pittsburgh , Pennsylvania , as the steepest . The Guinness World Records website lists no record for world 's steepest street , and mentions neither Baldwin Street nor Canton Avenue . Tilted disputes aside , here 's what life 's like at a slant . Twenty-five thousand balls of chocolate are rolled down the street each year . Every July , thousands of giant Jaffa candies are rolled down the 350-meter-long street in Dunedin 's annual Cadbury Jaffa Race . Each candy is numbered and participants can buy a corresponding ticket and hope their Jaffa will be the winner . All proceeds go to charity , and participants can wait at the bottom and get free candy . You may feel guilty having your mail delivered . Kevin Hanifin has been delivering mail on Baldwin Street for the past two years . He says he 's in better shape thanks to the route , and that the adjacent streets are no cakewalk , either , since they 're almost as steep . It 's always an entertaining walk , he says , since visitors often stop and talk to him . While Hanifin prefers to deliver the mail starting at the top of the hill , 17-year-old paperboy Hamish Lilly says going down is actually harder than going up . There 's no exercise like going home . Baldwin Street resident Dave Kernahan , 63 , started a weight-loss program after he lost his job and began gaining weight 15 years ago . His program ? Just going up and down his street . He runs up and down the street 30 times almost every day -- a total of more than 10 kilometers . His personal best is 105 times in one day . Tourists come from around the world ; residents are over it . When deciding to move to Baldwin Street , Sue Marshall says she was n't concerned about the grade , but rather the number of tourists who 'd be passing her home each day . `` I love meeting people -- you ca n't really go out of the front gate without meeting someone from across the world , '' says Marshall . She figures her husband has already shown up in more than 100 tourist photos while working in their garden , but says she 'd be doing the same thing if she were visiting . Meanwhile , she 's only been to the top of her street once and her husband has n't made it up yet . There are a few incentives to get to the top . Last year , Dunedin artist Daniel Mead painted a mural at the top of the street . He says one of the hardest parts about painting it was driving up the hill every day . `` It may have been a better idea to just walk as I think it ruined my car , '' he says . There 's a rumor that certain residents on Baldwin Street will offer visitors a certificate of completion if they can make the trek . Some bright soul also installed a drinking fountain .
