Kenya's Joyciline Jepkosgei won the women's London Marathon on Sunday as Ethiopia's Sisay Lemma triumphed in the men's race in the first full-scale staging of the event since the coronavirus pandemic.
Brigid Kosgei, aiming to become the first woman to win three consecutive London Marathon titles since Germany's Katrin Doerre in 1994, came fourth.
Jepkosgei won in a personal-best time of 2hr 17min 43sec. Ethiopia's Degitu Azimeraw finished second in 2:17.58 and compatriot Ashete Bekere was third in 2:18.18.
Lemma failed to finish the Olympic marathon in Japan in August but bounced back to win in the British capital in 2:04.01.
Kenya's Vincent Kipchumba was runner-up for the second year running in 2:04.28 and Ethiopia's Mosinet Geremew came third in a time of 2:04.41.
The London Marathon returned to normality for the first time since 2019 after being held without amateur runners or spectators last year due to Covid-19 restrictions.
The pandemic forced the event to be moved from April to October in 2020, with a small number of elite runners completing laps around St James's Park.
But this year more than 40,000 amateur runners joined the elite athletes in covering the traditional 26.2-mile course from Blackheath, southeast London, to The Mall, which leads to Buckingham Palace.
Another 40,000 runners competed virtually as the race got under way to cheers and applause from returning spectators under a blanket of cloud that later cleared.
The elite women set a ferocious early pace, completing the first 10 miles in 52min 10sec and threatening the women-only world record set in London in 2017 by Kenya's Mary Keitany.
Israel's Lonah Chemtai Salpeter, Kosgei, Jepkosgei, Bekere and Azimeraw formed a breakaway group after half-way.
Reigning New York Marathon champion Jepkosgei broke away after 1hr 55min, establishing an insurmountable lead with a few miles to go.
It is the first time five women have completed the London Marathon in under 2hr 19min.
Jepkosgei called her victory a "great achievement" as she basked in the vibrant atmosphere and autumnal sunshine at the finish line.
"I'm happy. The race was good. They cheered us all the way and motivated us. I'm so grateful and excited," she told the BBC.
"I'm so happy for the London crowd. Every kilometre there were people cheering all the way."
- Lemma bounces back -
The men's pack was touted as arguably the strongest in history despite the absence of Kenyan four-time London Marathon winner Eliud Kipchoge, with six runners holding best times of under 2hr 05min.
Defending champion Shura Kitata of Ethiopia, who failed to finish the Olympic marathon in Sapporo and entered the race carrying a hamstring injury, faded quickly.
The runners passed the half-way mark in 1:01.25 -- 12 seconds faster than Kipchoge's split when he set the men's London Marathon record of 2:02.37 in 2019.
A five-strong pack featuring Kenyans Evans Chebet and Kipchumba and Ethiopia's Birhanu Legese, Lemma and Geremew broke away as the race progressed before Lemma streaked ahead to win.
