(REUTERS) - Mo Farah will end his indoor running career with a 5,000m race at Saturday's Birmingham Grand Prix, the British Olympic champion said on Friday.
"I think tomorrow will be my last track race indoors," Farah, 33, told a news conference.
The two-time Olympic 5,000 and 10,000m champion eventually plans to turn to marathon racing as he continues his athletics career.
He said last year that 2017 would probably be his final season of running on the track outdoors.
Farah, Britain's most successful track athlete, defended his Olympic 5,000m and 10,000m titles in Rio de Janeiro last year. He has also won five outdoor World Championships.
