ORGANISERS of the annual Trowbridge Soapbox Derby are appealing for more contestants to help make this year's event the best ever.

The go-kart race has been held in the town every year since the mid 1980s. Teams can enter a go-kart made out of anything, from cardboard boxes to pram wheels, but the rules are strict.

Team sizes can vary but only one person is allowed to push the go-kart during the race with at least one person sitting inside.

Organisers from the Trow-bridge Round Table and the town's carnival committee will this year be awarding prizes for best fancy dress, as well as the trophy for the race champions.

Racers will begin congregating at Castle Street at 9am on August 31, with the town centre street closed for the contest. Entry is £1.

Organiser Nigel Hemmens said: "Soap boxes can be made out of anything as long as it is in the spirit of the event."
