Oamaru's fun-seeking Preston family is preparing for the trolley derby being held as part of this year's Victorian heritage celebrations.
The derby is being held on Saturday, November 21, with a new course down Wansbeck St.
Last year's inaugural event down Tyne St provided plenty of thrills - and a few spills - with Dunedin electrician Jaryd Grimwood blitzing the field.
Mr Grimwood lay on his stomach in his contraption to make it more aerodynamic, a feat Deane Preston described as "mad, but amazing".
The Preston family's interest in trolleys stems from when they were living in Levin, where a big trolley derby is held each year.
Mr Preston built a trolley for his daughters, Natalie (11) and Laura (9), "to have a bit of fun".
The Prestons, who own Oamaru Exhaust and Radiator, won the business class last year.
Competition was "hotting up" between businesses this year.
The Prestons planned to give $50 to the North Otago SPCA if anyone managed to beat them and were challenging other businesses to enter.
They were also building a cart to give to the SPCA's Junior Paws club.
There seemed to be a resurgence in trolley racing throughout the country.
It was good old-fashioned fun, Mr Preston said.
Scrutineering will be from 9am with racing beginning about 12.30pm.
