British sprinter Marlon Devonish has announced his retirement from athletics.
The 37-year-old, who won 4x100 metres relay gold at the Athens Olympics in 2004, is Britain's most decorated athlete with 18 major international medals.
"I have enjoyed the most incredible career and have had the privilege of competing and winning medals for my country for 16 years," Devonish said.
"Being injury free and staying fit and healthy is crucial to any success and I've managed to do that, but I'm getting older now and there are quicker athletes out there so I have taken this tough decision to stop at the right time.
"I'm going to focus my energies on coaching and public speaking. I want to coach within athletics and recently did a stint working with the GB relay team, but I will also work outside of the sport delivering sprint coaching in football, cricket and rugby."
Devonish is a co-holder of the Commonwealth record for the 4x100m men's relay, set in 1998, and last won a major medal in the same event, at Delhi's Commonwealth Games in 2010.
