Saturday night was an emotional one for Mo Farah, as he finally retired from track events after a glittering career as a four-time Olympic, and six-time World Champion.
He even had time to get knighted by the Queen.
Although, it was a bittersweet ending at the London Stadium at the World Championships.

He could manage only a silver medal in the 5,000m final, yet he took the applause of a rapturous crowd, and will retire as one of Britain's greatest ever athletes.
The excitement didn't end there for Mo, however, as he was caught on video enjoying the 4x100m relay final from the stands.
After putting so much work in over the years and achieving so much of his own success, it was great to see him relaxed and having fun as a fan.
His face was one of absolute shock as Britain took their first ever men's 4x100m gold medal, the Britons beating the well fancied teams of Jamaica and the USA to take the crown.
Of course, the race had largely been built up initially as Usain Bolt's final ever race.
Watch Farah's brilliant reaction to the relay race below.
One of the most iconic images of the 2012 Olympics was of Farah and Bolt posing together with their gold medals, and the two athletes careers have always seemed intertwined, with both men achieving unparalleled success on the track.
Farah must have had sympathy for the Jamaican, as he pulled up with cramp on the final leg and failed to secure his dream ending.
Both Bolt and Farah will now move on to the next step of their career, and although it wasn't the dream end for him, he is thankful for his experience in London.
“London is my home and it has been fantastic to be here again. The last week or so has been incredible. I’ve really enjoyed the journey.”
