Becky James, the former cycling world champion and double Olympic silver medallist, has retired at age of 25 and has plans to set up a baking business.
Becky James won the World sprint and keirin titles in 2013 and took silver at the same events at the 2016 Rio Olympics.
James released a statement on her Twitter telling fans "I have had time to think about my future and have decided to retire from international track sprint racing,".
She has been plagued by injuries during her career, and suffered a cancer scare in 2014 when she had an operation to remove abnormal cells following a cervical screening.
She first made a mark when representing Wales at the 2010 Commonwealth Games in Delhi, winning a silver medal in the sprint as well as a time trial bronze.
In the statement posted on her Twitter, she added how she was grateful for her success but that it was time to move on.
"After 13 years of racing my track bike, it is time to start an exciting new chapter in my life. I have given cycling 100% and know how much commitment it takes to make it
to the highest level in elite sport," she said.
"The pressure of competing at the top can be mentally and physically draining, but the rewards have been incredible and I have absolutely no regrets!
"I have achieved my dreams of becoming a world champion, a Commonwealth medallist for Wales and becoming a double Olympic silver medallist.
"I now want to enjoy my life without the strict training regime, while at the same time continuing to lead a healthy lifestyle both in body and mind.
