British sprinter Jamie Baulch has confirmed his retirement from athletics after a 15-year career.
The 32-year-old, who won medals at World, European and Commonwealth level, was part of the 4x400m team that claimed silver at the 1996 Olympics.
The Welshman also snatched gold in the individual 400m at the 1999 World Indoor Championships.
Baulch is eighth on the list of fastest British 400m times, setting a personal best of 44.57 seconds in 1996.
"I'd like to run faster but my body just can't do it anymore," Baulch told the Wales on Sunday newspaper.
Baulch said his career highlight came during the final of the 400m at the 1999 World Championships, when Michael Johnson broke the world record.
"I may have finished last in the final, but I was the first to give Johnson a congratulatory hug," he added.
