Mo Farah last night signed off on his last major competition at the World Athletics Championships in London with a silver rather than the gold he coveted. This was the first time he had failed to win gold at an global championships since 2011.
In a tactical race, Farah could not respond to a challenge for the first time in six years, turning his farewell race on the track at a major championship into a disappointment.
Farah, 34, is stepping up to the marathon and had hoped to add to the doubles he won at the 2012 and 2016 Olympics, and the 2013 and 2015 world championships.
The Kenyan-born athlete finished second by Farah in the 5,000m at the Olympics in Rio past year by 0.6 of a second.
"For me, it's not Mo Farah - and that's not to do a disservice to Mo, who is one of the greats of all time". I didn't have a single bit left at the end.
Everyone had expected the British distance runner to win gold but he was beaten by Muktar Edris of Ethiopia.

"Tactically, I was trying to cover every move and they [Edris and Ethiopian team-mate Yomif Kejelcha] had a gameplan".
In a thrilling finale featuring four athletes careering towards the line, Farah snatched back second place behind Edris, who clocked 13 minutes 32.79 seconds (13:32.79) after a searing final lap of 52.6 seconds. "I did the Mobot out of respect as well for him".
"It's been a long journey but it's been incredible", Farah told BBC Sport.
"The better man won on the day but I gave it all". It doesn't quite sink in until you compete here and cross the line - I had a couple of minutes to myself - that this is it.
They both failed to clear 1.97 metres - just one centimetre short of Johnson-Thompson's personal best - having jumped 1.95m and Ashley Bryant came 11th the decathlon with 8,049 points. "I got boxed-in early on - it doesn't normally happen - and couldn't get out".
