It will be some time before the last participant crosses the finishing line but there will be no more live text commentary I'm afraid because I haven't done the necessary training to go the distance. Thanks, as always, for joining us. You can watch highlights at 18:00 BST on BBC Two (22:30 BST on BBC Two Wales) and continue watching a stream of the finish line on this page until 16:00 BST. Until next year...

The oldest man running today is Paul Freedman. The 90-year-old has taken part in every London Marathon since 1991, except 2004 when he was recovering from a heart attack.
Memorably, one of Freedman's London Marathon top tips last year was to "follow a nice bum".
Jessica Hills is running in memory of her father, the Lambourn racehorse trainer John Hills, who died of pancreatic cancer aged 53 last year.
John, the son of Classic-winning trainer Barry, saddled more than 700 winners.
Jessica, who is raising funds for research into the illness which also claimed the life of her uncle Michael, passed the 30km mark in three hours, 16 minutes.
Before the marathon, she said: "My Dad was an incredibly kind and fair man who had so much more to give his family, all his hundreds of friends, and racing itself."
Many of the celebrities have finished and one of them is former Wales winger Shane Williams. The boy from Neath wanted to finish in under four hours and he achieved that. "I was in the lead at about 60m and after that it was downhill, but what an experience," he tells Gabby Logan.
Megan Lillie: Good luck grandad lee. Love you lots you're doing really well! Xxxx
Emily Blatchford: Good luck to my dad about to pass mile 24
Jane Susan Baxter: James Baxter we are all so proud of you (especially your Dad)

Part of the London Marathon's unique appeal is the members of the watching public fuelling the runners with their impromptu roadside tuckshop of jelly babies and the like.
Type 1 diabetic Jordan Silver won't be able to partake because his refuelling has to be planned with military precision. He's gone through 25km in two and a half hours - you can read more of his inspirational story here.
Certainly not. Tracey Irwin is out to prove otherwise at the London Marathon today having been inspired by an internet campaign.
"What are the chances of a plus-size runner going out and running 26 miles?," Tracey says. She's one of six inspirational stories BBC Get Inspired caught up with in the build up to today's race.
Of the thousands who are running the London Marathon today, there are more teachers than any other occupation. For those interested, there are 10 game keepers running, 106 actors and eight librarians. Thanks for listening.
The London Marathon is getting you out running already it seems. If you fancy getting into running, Get Inspired's activity finder could put you in touch with a club in your area.
Lee Haward: I have noticed an increase in the amount of people out jogging today. I can't think why! #getinspired
Dan Lawrence: Watching the London marathon really does inspire you to get out and exercise.
Paula Zucherelli: If 37k people went out this morning to run London Marathon how could I not do my humble 4k?

People are running the London Marathon for a number of reasons, some are hoping to achieve a lifetime's ambition, others doing in in memory of loved ones. Everyone has a target, everyone has a story to tell.
Somewhere in the crowd is Katey Cuthbertson, who is running 1,000 miles in 1,000 days in memory of her sister and dad who both died of cancer.
The 30-year-old's challenge includes climbing the three peaks, mud runs, half marathons and rowing marathons before bringing the challenge to an end in London.
Apparently the winner of the men's race Eliud Chipchoge has been running 12 miles a day since he was eight.
I'm not for a minute suggesting you all should embark on a similarly gruelling regime.
But if you've been inspired by today's London Marathon BBC Get Inspired have produced a step-by-step guide into mass participation events.
Susan Bentley: A shout out to @BethThomasHanco inspires @uniofbrighton students to volunteer in community.
Alison Gilleard: Big shout out for my friend Jayne Cobbing
Running Forever: Well done Gerry Hogg! 2:41:05 whoop whoop!

Jenson Button finishes in 2:52.30 and says he is "chuffed" with his time.
"The most amazing thing is, I've done quite a bit of training but there are so many people in front of me," says the former Formula 1 world champion. "People have put in so much effort and it's actually quite emotional. It was really cool."
Two-time winner Wilson Kipsang, who came second in this year's men's race, told BBC Sport: "This is one of the best races and it was a really strong field.
"I'm happy for my friend to have won and for me as defending champion to run a good time and get second place, I'm really happy. It was a very tough race but a fantastic one."
Men's winner Eliud Kipchoge told BBC Sport: "The race was good and I feel OK. This is a major championships and it was like an Olympic Games.
"To only have 500 metres to go and be next to someone like Kipsang shows this is a major competition. The crowd were wonderful and they lifted my spirits."
Gemma Semmelroth: Watching from Germany to try to spot Jim Semmelroth in an Ironman costume.
Ahmed Ashour: Go Shafi. All Ashour family and Birmingham are rooting for you.
Susannah Sutton: Tracking the fab race through London between Hutch dad & son. Dad just 3 mins ahead!!

Paula Radcliffe said she was unfit, she said she was unprepared, but she finished four seconds slower than one of Britain's elite women, Rebecca Robinson, who finished 40th.
She was only five minutes behind Britain's best placed elite woman, Sonia Samuels. An incredible performance by a 41-year-old who injured her Achilles a few weeks ago and was struggling to walk a couple of years ago.
More from Paula Radcliffe: "It was so loud, my ears were ringing. It was just amazing the whole way round. All the way along, there were so many people giving me encouragement.
"I came into this race totally unprepared and hoped the magic of the London Marathon would help me and I'm sure it did. You can't help but come here and run hard. You have to give it your best effort and that's what I did.
"When I knew I was going to finish I just wanted to thank as many people as possible."
Paula Radcliffe says: "Down the last mile I thought 'I don't care about the time' I just wanted to thank as many people as I could.
"You can't come to the London Marathon and not give an honest effort. But I went off way too fast but from then on it got more and more emotional.
"There was a big sign at Embankment saying 'we will miss you' but it won't be as much as I will miss you."
Paula Radcliffe's husband Gary is lost for words. He attempts to answer Gabby Logan's question but he has to stop to prevent salty tears running down his cheeks.
"I didn't care about the time all the way round and I just wanted to thank as many people as possible," says Radcliffe. "I went off way too fast and then it got more and more emotional. It was just amazing the whole way round."
"We will never see her like again, certainly not here in Britain," says Steve Cram of Paula Radcliffe.
Radcliffe's children, Isla and Raphael, appear with husband Gary and an emotional Isla is crying, overwhelmed by the occasion. It's unofficial but Radcliffe's time was about 2:36.55
"Thank you," says Paula Radcliffe as she approaches the final turn, holding back the tears, waving at the crowd. Buckingham Palace is now behind her, she runs hand in hand with a gentleman down the home straight before letting go to savour the moment.
Spiderman crosses the line - which is a new world record (probably) for someone dressed as a superhero. Paula Radcliffe's family are waiting at the finishing line and they won't have long to wait because the Briton is about five minutes from the finish line and is set to clock two hours and 37 minutes.
So, your legs have turned to guacamole but you've still got plenty of miles left to go. What do you do? Give up or carry on? What would be your number one tip to help someone get to the finishing line? Tweet us using the hashtag #getinspired
The motivations for running the marathon are often moving and the story of the Martin siblings certainly is.
Rosie, 24, Ella, 22 and Will, 20 are all delivering on a promise they made to their terminally-ill, running-mad mum Sand.
Remember, you don't have to run a marathon to get into running - BBC Get Inspired's handy guide tells you everything you need to know about recreational running.
BBC athletics commentator
"She's an incredible character and when you talk about role models in sport you couldn't find a better one.
"When you go out on any evening in Britain people are out running, lots of women are out running, and Paula has had such an impact on inspiring people to have a go.
"Paula Radcliffe is a running icon. She's enabled hundreds of thousands, maybe millions, of people to get off their backsides and go run."
Time to focus our attention on Paula Radcliffe for a bit. That familiar sight, the bobbing head, is easy to spot in the crowd.
It's difficult to tell whether she's smiling or grimacing. It might be both. The world record holder, red vest, shades and knee-high white socks, has enough energy to wave to the crowd at least.
What a gentleman Eliud Kipchoge is, embracing world record holder Dennis Kimetto as he crosses the line in third. As you'd expect, it's a Kenyan top three and all three are smiling, happy with their day's work.
Former world champion Eliud Kipchoge looks over his shoulder before turning the corner to soak in the applause of the crowd down The Mall.
"This will be the biggest day of his marathon career," says Steve Cram.
Wilson Kipchoge is trying to haul him down but Kipchoge has time enough to salute the crowd. A well-timed break. A comfortable victory.
And still they go toe-to-toe. In the shadow of Big Ben, Wilson Kipsang and Eliud Kipchoge are shoulder to shoulder but with a mile remaining Kipchoge ups the ante and opens a gap between him and his compatriot.
Some of you are catching the marathon bug watching this year's London Marathon.
Sally Eccleston: Plan for today - #getinspired for a future London Marathon whilst listening to 5 live sport and working
Kat Chase: Cheeky little 6 mile Sunday morning run, inspired by 40,000 people running slightly further!
If you fancy taking on a marathon or a similar event, it's worth reading this.
Defending champion Wilson Kipsang and former world champion Eliud Kipchoge are racing side by side. They've left the others behind them and it's doing to be a battle royal between the two Kenyans. Both look to have plenty left in the tank. Get ready for fireworks.
For some toddlers, watching the London Marathon is more entertaining than Mr Tumble.
