Haylay Letebrhan Gebreslasea (2:36.51) and Lemma Ayelu Geda (2:36.53) battled to the line in the women's race, ahead of Bizuayehu Ehite Gebireyes (2:37.28).

Hong Kong's Christy Yiu Kit-ching, who will be competing in the marathon at the Rio Olympics this summer, finished sixth.

Ten runners were admitted to hospital, six men and four women, said athletics chief William Ko, but none were thought to be serious.

That brings our blog to a close, thanks for coming.

Blimey, the rain has actually stopped. No use to much of the field, but perhaps those still out there as we approach the five-hour mark will appreciate a break.

Just spoken to women's winner Haylay Gebreslasea, who was delighted with her first ever marathon win. 

The Ethiopian finished fourth here last year and said that experience had helped her a lot. 

The 25-year-old hopes to use some of her winnings to help introduce youngsters to running in her hometown.

Hong Kong's Christy Yiu Kit-ching is going home HK$56,879 richer after finishing sixth in the marathon, but was still disappointed not to break her PB, despite the weather. 

"I'm a little bit disappointed because my minimum standard was to break my PB. Today the first half was a bit too slow.

"The top foreign runners ran very conservatively, when I sped up they followed, when I slowed down they followed. No-one wanted to lead the pack. I led for around 13km

"But this was the first time I could follow the lead pack so maybe next time I'll learn from their strategy."

Impressive result for Hong Kong's Christy Yiu Kit-ching, who finished sixth overall in the women's marathon. She was a full seven minutes faster than last year, and narrowly missed out on a PB despite the downpour.

It bodes well for her hopes as she heads to Rio in the summer for the Olympic marathon

Meanwhile, the top three places were filled by Ethiopians, with Haylay Letebrhan Gebreslasea (2:36.51) and Lemma Ayelu Geda (2:36.53) fighting out a sprint finish. Third was Bizuayehu Ehite Gebireyes (2:37.28)

9.30am

The elite marathoners have finished but the rain is heavier and heavier and it's going to be a tough time for the amateurs. 

It was a Kenyan one-two in the men's, Mike Mutai Kiprotich beating Lawrence Cherono by a couple of strides in a sprint finish from 50 metres out. They finished on 2 hours 12 minutes 12 seconds and 2:12.14 respectively, ahead of Ethiopa's Gemeda Dadi Feyera (2:12.20)

Kiprotich said the humidity in the Western Tunnel was extremely tough to cope with. 

"The weather was not good but we just had to try our best. Despite the condifitions, I really enjoyed the race," he said.

"The conditions were similar to what I've trained in in Kenya, so it wasn't too much of a problem.

"First time in Hong Kong and the city is very good, I like it and want to compete next year again.

"My PB is 2:09 so I can go better but it was a good day."

8.45am

Hong Kong's world champion snooker player Ng On-yee has been in action today – the fifth time she's competed in the 10k.

She said her time was about eight minutes slower than previous years, but she really enjoyed running in the rain for the first time – a bit of a change from conditions normally found around the snooker table.

She has a busy few months, with her title to defend in the ladies world championship, then taking on the men in theirs, and said keeping fit is vital to help maintain her concentration while competing

Fung Ying-ki made it back-to-back triumphs in the 10km wheelchair race Sunday and said afterwards he hoped his achievements would inspire more Hongkongers to follow his lead, reports Mathew Scott.

“For as long as I can I will keep competing and I hope this will inspire more wheelchair athletes,” said Fung, who crossed in 28 minutes and 51 seconds.  “Each year we are seeing more competitors in these kinds of races and this is encouraging for all of us, and for those who might not have tried racing before.”

8.25am

Hong Kong's Gi Ka-man, one of the top local runners, has hit out at organisers for their lack of support after he got injured in the Western Tunnel during the half marathon.

He said he was just told to jog back, without even a jacket or blanket to keep warm, and had to make it back to Central himself after pulling a muscle while running with the leader. 

He said he was so cold in Central that he had to try to force himself to jog despite the injury and felt "helpless"

He urged organisers to improve, saying that after a similar problem during a race in Tokyo, he was quickly given a down jacket – and a train ticket.

7.45am

The rain is still bucketing down, but the early winners are in.

WATCH: Reaction from the 10K winners

Kate Rutherford, a 42-year-old mother of two, was an impressive winner in the women's 10k in 39.18 – remarkably, she said it was only her "second ever road race. Second and third was local elite triathlete Hilda Choi Yan-hin (39:22) and Yu Wing-hay (39:47)

Li looked more surprised than delighted when he broke the rope for a repeat victory.

"I didn't really give myself a chance this year," laughed the 25-year-old. "I've had trouble with the instep on both of my feet and have only been able to run twice in the past month – and only 10km each time. But maybe that helped. I felt fresh starting the race – but I am exhausted now."

Half-marathon – Women

1 Mary Joy Tabel - Philippines - 1:21.41

The 26-year-old surged through the field soon after the start and by about 2km was out on her own, a position she held right to the wire.

"I started behind the elite runners but knew in these wet conditions I had to get to them quickly," said Tabal. "Once I did, I just thought to myself 'run as fast as you can'."

Welcome to our coverage of the 20th anniversary edition of the Hong Kong Marathon, which is underway in the cold and rain. 

There were fears it might have to be called off if the T3 or red rainstorm flag was up overnight, but it's just miserable rather than dangerous, so off the 74,000 runners – spread across 10k, half and full marathon – went.

We'll update regularly with all the latest results from a soggy finish line at Victoria Park - if our laptop doesn't short out.
