Four-time Olympic champion Mo Farah's hopes of ending his track career at the Tokyo Games ended as he fell short of the qualifying mark for the 10,000 metres in Manchester on Friday. 

The 38-year-old won a specially-arranged race to give him a final chance to qualify at the British Championships, but his time of 27 minutes 47 seconds was nearly 20 seconds off the time required to qualify. Farah won the 5,000m-10,000m double at the London Olympics in 2012 and repeated the feat four years later in Rio de Janeiro. He then turned his attention to the marathon, but after mixed results returned to the track in the hope of one final shot at Olympic glory.
