Britain’s Olympic medallist Cassandra Patten has announced her retirement because of an oingoing shoulder injury.

Patten, 24, who won the bronze medal in the 10 km Open Water at the 2008 Olympic Games in Beijing, also has two World Championship silver medals for the same discipline.

"I'll miss everything about swimming," said Patten. "I'm not retiring because I don't love the sport anymore it is just because my body won't let me.”
