Interestingly, Keninisa Bekele, in seventh, doesn't appear to be losing any more time to the lead pack of six...
Here's the moment eight-time champion David Weir sprinted to a third place finish at his 23rd consecutive London Marathon.

Rain? What rain? The sun is now making an appearance in London!
Back in the elite men's race, Keninisa Bekele has been dropped.
Six athletes remain at the front, including 2021 winner Sisay Lemma.
A brilliant run from Yalemzerf Yehualaw - and she's only just getting started.
The 23-year-old Ethiopian storms to victory, crossing the line just outside her personal best in 2:17:26.
A huge victory. It's 2021 champion Joyciline Jepkosgei next to finish followed by Alemu Megertu.

Which celebrities are taking on the London Marathon today?
Let's take a look. Singer and songwriter Cynthia Erivo, actor Stephen Mangan, McFly drummer Harry Judd, radio DJs Chris Stark and Reece Parkinson, reality TV star Mark Wright, pundit and former England footballer Danny Mills are among the recognisable faces you may be able to spot over the next few hours.
The first ever women’s Olympic marathon Joan Benoit-Samuelson is also signed up, as is double Olympic rowing gold medallist James Cracknell, Olympic eventing champion Tom McEwan, along with former Olympian Iwan Thomas.
Yes Joan! Incredible effort.
There's certainly no shortage of eye-catching fancy dress on show around the course.

The fastest pint on the planet would be some achievement!
Image source, TwitterA five minute 11 second mile leaves just two standing at the front of the women's race.
And it's the two athletes many would have expected. Defending London Marathon champion Joyciline Jepkosgei, of Kenya, and the 23-year-old Yalemzerf Yehualaw, from Ethiopia.
Yehualaw continues to push the pace, and now Jepkosgei is under real pressure...
The man with the third fastest marathon time in history is also running on the streets of London today.
Ethiopian Birhanu Legese set his personal best at the 2019 Berlin marathon, clocking 2:02:48 as he finished behind Keninisa Bekele.
Third place that day was Sisay Lemma. Will history repeat itself?
Legese, who has time on his side aged 28, finished fifth at last year's London marathon in 2:06:10.

The race is very much on in the women's event.
There's a group of five at the very front, including 2021 champion Joyciline Jepkosgei, Yalemzerf Yehualaw, Judith Korir, Sutume Kebede and Alemu Megertu.
And now Kebede falls off the pace. Four remain.

Here's the moment Sisay Lemma clinched victory last year, and the scenes he will have been dreaming about last night.
The men remain on course for a sub 2:05 finish as they get stuck into the second half of the race.
London Marathon 2021: Sisay Lemma takes men's title
Oh, a slip for Yalemzerf Yehualaw!
The Ethiopian, one of the pre-race favourites in the women's race, hits the ground following a speed bump in the road.
A trip? A slip? It's not quite clear. But she's up and settles back into the lead pack.
It's going to be tough for Sisay Lemma to defend his title today.
The 31-year-old is facing quality competition - not least from compatriots Keninisa Bekele and Birhanu Legese.
He'll do everything he can to back up the biggest win of his career, which saw him post the sixth fastest time in the race's history, and he'll hope he can celebrate properly this time.
Following his win last year, Lemma was not allowed to stand on the podium after coming into close contact with fellow Ethiopian Kinde Atanaw, who tested positive for Covid.

Image source, Getty ImagesOnly Eliud Kipchoge has run a faster marathon in history than Keninisa Bekele.
The Ethiopian, who ran ran 2:01:41 in Berlin three years ago, is one of the greatest distance runners of all time and has three Olympic titles among his achievements.
Until Kipchoge's world record run in Berlin last month, the gap between the pair's marathon personal bests stood at two seconds.
On whether this might be his last race, the 40-year-old Bekele said: "My mind tells me not yet. I follow the feeling in my mind. Someday maybe my mind will tell me this is enough, stop here, but now is not my time.”
The leaders in the elite men's race pass 20km in 59:12, with Keninisa Bekele tucked in behind the pacers across Tower Bridge.
The Ethiopian said he is here to win today in his fourth London Marathon. Just how good is he feeling today?
