From from Mo Farah: "I started here at the mini marathon and to finish here is just incredible.

"If somebody had said to that kid running the mini marathon that I'll be Olympic champion, he would never have believed it. The sport needs this, we need to give back to the young athletes and teach them what is possible with hard work.

"I want to pass that on. The Great North Run is going to be my last ever run and that will be my goodbye. My career has been amazing, my wife and kids have been with me throughout this journey and I want to give time to them now, as well as getting involved in grassroots sport and give back to this sport."

Sir Mo Farah on BBC One: "London has been so great to me over the years and I wanted to be here to say thank you to the crowd and the support that was just amazing.

"Training went well, and I was confident and I thought I could do between 2:05 and 2:07 but you never know with the marathon.

"I gave it my all but my body just wasn't responding and that's when you know when it's time to call it a day.

"Part of me was wanting to cry. The people were amazing, even in the rain to line the streets and that's what this is all about. It's what has kept me going for so long throughout my career.

"I will miss that feeling, I am emotional today."

Only in the London Marathon...

This was always going to be Mo Farah's final marathon but he has just confirmed the Great North Run in September will be the final race of his career.

Mo Farah is speaking on BBC One.

He says he wanted to cry going around the course because of the support he received.

Remarkable. We have been treated to some brilliant elite races today.

Now, though, attention turns to the thousands of people who are out on the streets of London running the marathon for their own reasons, many raising thousands of pounds for charity.

There are some inspirational stories and we'll focus on them over the next period.

More from women's winner Sifan Hassan on BBC One: "London has been my dream. And now here I am, I was doubting that I could even finish.

"This is just amazing. I will never forget this in my whole life.

"I enjoyed it so much. They said the marathon would hurt but I felt really good, even after 5km and 15km! When I saw the finish line, I thought, is that really it?!

"This year, the world championships is in my mind, I wasn't really thinking about the marathon. I thought I would have to cancel this run to focus on the worlds in Budapest. But I am so happy."

Women's elite race winner Sifan Hassan on BBC One: "It was just amazing. I never thought I would finish a marathon and here I am winning it!

"And it is one of my favourite marathons in the world. The crowd was so amazing and every single kilometre I was so grateful for them. I wasn't going to stop.

"I had a problem with my hip, which made me stop. But it started to feel a little bit better.

"And then I missed one of the drinks stations! I didn't practice that part of the race because I have been fasting and so that was quite difficult. But I needed it!

"At 20km I knew that I could kick on because I didn't feel that tired and I didn't care how I finished, I just wanted to get there.

"I wasn't thinking about winning or how fast I was going to be and I think that was a good thing for me today. I felt really popular here today because the crowd were cheering me so much!"

This is an amazing interview.

Sifan Hassan is laughing and giggling with her head in her hands.

I don't think she can believe what she has done.

Sifan Hassan is speaking on BBC One right now!

You can watch at the top of this page.

We have seen some extraordinary sport in the last 40 minutes.

First Sifan Hassan, on her debut, won the London Marathon.

In the early stages she pulled over to the side of the road, seemingly injured and went and won it...

It doesn't get any easier, does it?

There is no stopping Father Time and no matter how much you have done in the past, you have to pass the baton to the next generation and we have seen that today from Mo to Emile Cairess and Phil Sessemann.

They would have loved watching Mo all of these years and he has inspired so many.

He can now ease his way in to retirement and he has certainly deserved it.

Mo Farah certainly would not have wanted a sprint finish in his final marathon in the final straight!

But that is a wonderful run from Phil Sessemann.

Thank you for everything, Mo. Thank you for being here.

Mo Farah is tired.

He is picked off by another Briton Phil Sesemann in the home straight.

Farah then follows him over the line for the final time in a marathon. This is likely his last major race too.

Steve Cram
Marathon commentator on BBC TV

A stunning performance in his first marathon and he can be so proud of that run.

He is ahead of a lot of great athletes.

We are now waiting for Mo Farah's farewell finish.

Emile Cairess comes across the line in sixth.

We think that makes him the third-fastest British man in history.

It's his marathon debut.

Mo Farah should be across the line in his final marathon race shortly.

Emile Cairess has stuck to his plan the whole way through. We thought he might be ambitious with how quickly he started but has committed and has been phenomenal.

Kiptum's fellow Kenyan Geoffrey Kamworor gives him a huge hug after crossing the line in second.

Britain's Emile Cairess is up into sixth, by the way. This is an extraordinary effort from the Yorkshireman on his marathon debut.

He's into the closing stretch.
