Britain’s former BMX world champion Liam Phillips has retired from the sport after failing to recover from “career ending” injuries.
The 28-year-old injured his hand and wrist in a crash in February.
Phillips became world champion in 2013, was a two-time Olympian, crashing out in London and Rio, and won 10 gold medals at the BMX Supercross World Cup.
“I can honestly say that I achieved more throughout my career than I ever thought possible,” he said.
Phillips broke his collarbone 12 weeks before London 2012 and then again eight weeks before Rio 2016.
He said: “Becoming world champion and wearing the rainbow jersey was the proudest 12 months of my career.
“Winning a home World Cup four years on the bounce and striving to be the best in the world on a daily basis are memories that I’ll always cherish.”
Phillips added that he wanted to continue working in the sport, saying: “I would like to help athletes who have talent but need some guidance to help plan, prepare and shape their programmes.
“If I’m no longer able to compete myself, it feels right for me to assist others in their quest to achieve their goals.”
