Mo Farah's rivals must be tired of seeing the British long-distance runner indulge in his trademark celebration in recent years.

And it would be no surprise to witness the 5000m and 10,000m Olympic champion perform the 'Mobot' yet again after striking gold at Rio's Joao Havelange Olympic Stadium in August.

Farah showed a blistering turn of pace to win his first Olympic title on home soil in London four years ago when he took the 10,000m to round off a famous day for British athletics, which was dubbed 'Super Saturday'.

Somalia-born Farah had another gold medal around his neck after winning the 5000m a week later to confirm his status as the king of long-distance running.

There was no catching Farah when he completed the 'triple' double by retaining both of his world titles in Beijing last year, with Caleb Mwangangi Ndiku of Kenya and Ethiopa's Hagos Gebrhiwet taking silver and bronze respectively over the shorter distance and Geoffrey Kipsang Kamworor and Paul Tanui denied in the 10,000m.

Farah trained at high altitude in Ethiopia as part of his preparation for Rio and the 33-year-old knows he will face a major battle to hit the heights again as he enters the twilight of his career.

"It's going to be a lot harder than London 2012," said Farah. "I'm older and I think it's definitely going to be a stronger field so it's going to be a real battle.

"Geoffrey [Kipsang Kamworor] and Bedan [Karoki Muchiri] will be the main challengers over 10,000m and they're probably going to go from the start. But I don't know whether they're capable of running around or under 26.40.

"That's what I have to do if I want to win. It's not rocket science."

Farah endured a difficult time in 2015 when he expressed frustration at being faced with questions about doping allegations which he said were "killing him", following media claims against his coach, Alberto Salazar.

Britain's greatest long-distance runner maintained he is "100 per cent clean", before proving he is still the man for the big occasion on the track in China last year.

Farah has warned those attempting to dethrone him "the track is mine" as he plots more Olympic glory, and his rivals may well be braced for another all-too familiar rendition of the 'Mobot' in Brazil.
