Sir Mo Farah triumphed at the Diamond League in Birmingham as he signed off with his final track race in Britain.

The four-time Olympic champion took victory in the 3,000m at the Alexander Stadium in seven minutes 38.64 seconds on Sunday.

He will retire from the track at the Diamond League final in Zurich on Thursday to focus on marathon racing.

Farah said it has been an “amazing” time for him but insisted his focus on Sunday was winning the race, rather than getting caught up in the occasion of it being his last track event on British soil.

He said on BBC One: “It’s been an amazing week. Emotion was high, not as high as London (at the World Championships), but one last time at home, great support from the home crowd, really enjoyed it.

“I was just trying to think about the race and how to win and who’s there, and tactically get that right.”

Farah, who thanked the fans in attendance and everyone who has supported him during his career, admits he is now looking forward to competing with a little less pressure on him as he prepares to switch to marathon running.

“I had an amazing career and I just want to continue and see what I can do on the road, without having the pressure and just really enjoy it,” he added.

“Because what you forget is, as an athlete, is something like a hobby, something that I enjoyed, became a job. Because I love it, I love what I do, but at the same time it can get a little hard when you have so much pressure, you just can’t go anywhere.

“But now going to the road it’s going to be a complete new game, a new mind, and I’m excited.”
