Friends of Henry Surtees swim the Channel in his memory

Worth School swimmers and a support boat set out from Dover at 0600 BST

Students at the school attended by racing driver Henry Surtees, killed in a crash last July, have completed a cross-Channel swim in his memory.

Mr Surtees, 18, had just finished his A-levels at Worth School, West Sussex, when he died in a crash during a Formula Two race at Brands Hatch, Kent.

The pupils swam the 21-mile relay event in 13 hours and 13 minutes after setting out from Dover early on Monday.

"It's been absolutely fantastic," said organiser Dominic Robinson, 17.

"The weather was really great the whole way across.

"It has been really nice bringing everything to an end, it's the culmination of so much effort."

The students trained three to four hours a week for the challenge, as well as doing weights and fitness sessions.

The other swimmers were Nick Elvidge, Nick Gandy, Rory Pickard, Ben Clyde-Smith, Sasha Richards and reserve team member Raphael Gruber.

They aimed to raise £15,000 for the Sussex Air Ambulance, the chosen charity of Henry's family, Headway, which improves life after brain injury, and the Matthew Elvidge Trust.

Mr Surtees was the son of former Formula One world champion John Surtees, who lives in Lingfield, Surrey, and is the only man to have won world titles on both two and four wheels.

He claimed multiple 500cc motorcycle world championships before winning the F1 crown with Ferrari in 1964.
