Surprise women's winner Ines Monteiro destroyed the field with a national record as her brilliant solo run wrapped up a one-two for Portugal.
Compatriot Ana Dulce Felix (53.58) grabbed second place ahead of Australian Benita Willis (54.41) in third, but Monteiro's victory was rarely in any doubt as she coasted home almost 90 seconds ahead of the rest of the field.
Monteiro showed her intent early in the race to hit the front and had opened up a sizeable lead inside two miles.
Although the Portuguese star would make the occasional glance over her shoulder to check on her rivals, she needn't have bothered as she tore away from the chasing group.
With two-time world marathon champion Catherine Ndereba struggling in her battle against the gusts of wind coming off the Solent, Monteiro made light of the tricky conditions and went it alone to post a
Portuguese 10 mile record in 52 minutes 32 seconds.
Monteiro said: 'I really enjoyed the race. I felt that I ran well and I was waiting for other runners to come with me. But nobody did.
'It was difficult at times – especially along the seafront. But I felt good in my running and enjoyed the experience.'
Ndereba admitted that the conditions had wrecked her race as she came home in fifth place in 55.28.
She said: 'The wind totally destroyed me and blew me all over the place.
'It was so hard out there but although it was difficult, it was also a lot of fun. There were a lot of people cheering you on.
'But this is a great race and I tried my hardest.'
Claire Hallissey, who finished 25th at the World Half Marathon Championships a fortnight ago, was Britain's top finisher in seventh position.
