Canoe slalom’s David Florence and boxer Amir Khan and have both announced their retirement after a combined 38 years at the top of British sport.
Khan was Team GB’s only boxer at Athens 2004 and the then 17-year-old burst onto the scene with a lightweight silver medal.
The Bolton ace was Team GB’s youngest boxer since Colin Jones in 1976 and won four fights before losing to Cuba’s Mario Kindelan in the gold medal match.
He turned pro shortly after and went on to become the unified light-welterweight world champion and win 34 of 40 professional fights.
"It's time to hang up my gloves," Khan posted on social media. "I feel blessed to have had such an amazing career that has spanned over 27 years."
"I want to say a heartfelt thanks to the incredible teams I have worked with and to my family, friends and fans for the love and support they have shown me," he added.
Khan is not the only Team GB medallist to announce his retirement, with canoe slalom’s Florence calling it quits after 21 years.
Florence won three Olympic medals for Team GB, starting in Beijing in the C1 category and then at London 2012 and Rio 2016 in the C2 alongside Richard Hounslow.
He also won three World Championship golds and 25 World Cup medals.
“I’ve been really fortunate to have had so many great experiences and get to do something I love for so long. I feel really privileged,” he said.
“There are so many highlights, to go into the Olympic Games in 2008 and win that first Olympic medal was really special and then to win the world championships in C1 and C2 on the same weekend (in 2013).
“I've loved going to the Olympics, winning medals but what’s kept me motivated is the enjoyment of trying to improve and trying to be my best.”
