Thrills, spills and some pretty wacky contraptions entertained the crowds who lined the streets to see the action in Norfolk's biggest soapbox rally.

More teams than ever raced their handmade karts down the hilly streets of Hunstanton on a new, and very much faster, course starting at the town hall and finishing near the seafront bandstand.

In total 49 teams from all over Norfolk, and as far afield as Newark, Wellingborough and Milton Keynes, got the push-off from the starting grid as they competed in the Searles Soap Box Derby on Sunday.

Since being revived in 2017, the races have been a big hit and proved no less competitive or fun for the crowds who packed the side of the route this year.

The 'gravity vehicles' careering along a downhill course included everything form a mini recreation of the Mystery Machine from Scooby Doo to, fittingly in the 50th anniversary year of the moon landings, one named after Apollo 11.
