It's a much better rhythm in the men's race now and it's probably only a comfortable speed for a few of these guys, but they've made the decision to stick with the leading pack. Mo Farah looks like he has slotted in nicely in Eliud Kipchoge's slip stream.
Elite men's race
Eliud Kipchoge of Kenya is the Olympic champion and has taken the London title twice before.
He's leading the front pack in the elite men's race, clocking 43:05 minutes at the 15km mark.
Look who's joined the party, though. It's Mo Farah! He's around sixth place at the moment and has managed to recover from his earlier problem at the drinks station.

Wishing Ross Bannister (42321) all the very best in the London Marathon all the way from Riveria Maya in Mexico. Congrats on raising an amazing amount of money for Macmillan Cancer - a great charity especially after everything he has been through over the last 12 months.

Incredible numbers!

What a finish this was.

Is Mary Keitany struggling?
The defending champion from Kenya still leads the women's race but she's really fallen behind the male pacemakers.
At the 25km mark, Keitany still leads Tirunesh Dibaba by 29 seconds.

That's a huge win by Madison de Rozario.
She has done a bit of road racing but never been in a lead pack in this way. I wonder if the rest of the pack underestimated what she can pull out in the final few meters.

It's a first London title for Madison de Rozario!
She's a surprise winner ahead of four-time champion Tatyana McFadden.
Rozario finishes in 01:42:58 to take the victory, which comes just a week after she won two golds at the Commonwealth Games on the gold coast.
Susannah Scaroni comes in third for the USA.

Farah needs to not panic and not let it get to him.
If he takes another type of fluid he will be OK even it's not his drink that he will have trained with. It’s more important not to lose rhythm. He is just going to have to take on board what he can and settle back into the race.
He's using adrenaline that he doesn't want to be using. He is also showing the other guys in the pack that he has a problem and he doesn't want to be doing that.

Now we're heading for sprint finish in the women's wheelchair race.
They're coming round the final corner now.

This is how chilled Mo Farah was at the start line.
He's not in the same mindset now. Farah is trying to get a drink in his hand by asking someone on the accompanying safety motorbikes.
They can't help him. He's really stressing and looks out of his comfort zone right now.

That sprint finish by David Weir was so perfectly timed.
As they came round the bend it didn't look like he would have that kick, but as he sees the finish line he has that final burst. He was going so fast at the end they didn't even manage to let go of the tape, his helmet smashed through it.

Phil Woodford: David Weir - incredible ride.
Catherine: What a hero!
Kelvin Moon: Didn't think he was going to make it then! Another great win for David Weir!

Drink drama for Mo Farah.
The Briton gets to a water station and can't find his bottle. He has his own bottle and it's not where he thought it would be.
The four-time Olympic champion eventually grabs a drink and gets back to business, but he gesticulates in anger after this set back.

The Weirwolf dominates London again! What a finish!
David Weir made an incredible sprint for the line and secures his eighth London Marathon win with a time of 01:31:15.
Like last year, Switzerland's Marcel Hug finishes second with young Daniel Romanchuk of America in third. A brilliant achievement at the age of just 20.

The wheelchair athletes are in the final mile of their race and we're heading for a sprint finish.
Marcel Hug, last year's runner-up, 2017 champion David Weir and American Daniel Romanchuck have pulled away.
Brace yourselves...
Elite men's race
The men's race has started in lightning quick time.
Guye Adola of Ethiopia is out in front, with Britain's Mo Farah safely tucked in in ninth position.
The front pack have clocked 13:48 minutes in the first 5km, which is absolutely mind-blowing for someone who runs 5km in half an hour. These guys are superhuman.
