Our video shows scenes from the Race for Life at Southsea.
A sea of brightly-clad women and their supporters engulfed the Common to make this year’s Race for Life one of the best ever held.
They came wearing everything from wigs and tutus to angel wings and cowboy hats – and just about every accessory was pink.
Grandmas walked with their families and young children rode atop their mummys’ shoulders.
And although the youngsters couldn’t have grasped the full significance of what they were part of, they surely realised it was something very big.
Cancer Research UK area events manager Fiona Miller said Portsmouth’s was one of the most successful Race for Life events in England.
She said: ‘Portsmouth overtook Southampton a couple of years ago, so it’s the biggest one in the south.’
About 1,800 people took part in a 10km race, while 5,500 participants ran, jogged and walked in a 5km event.
Organisers are hopeful more than £440,000 will be raised from the event for Cancer Research UK.
Ms Miller said cancer was something that affected everybody in some way.
She said: ‘The commentator said “everybody put your hand in the air if you’ve been affected by cancer”, and pretty much everybody did.
‘We know that there must be a cure, we’ve found ways of treating it, so we just have to keep raising as much money as we can and one day we will beat it.’
Organisers don’t record the winners’ times or names – the only thing to beat in this race is the disease.
But the first over the line in the 10km race was Sarah Gardiner of Fareham.
Sarah, 41, said she had taken part in the race every year since 2010. She said the atmosphere of the event was part of what kept people coming back.
It’s really good fun and it’s obviously for a great cause,’ said Sarah. ‘Everybody’s affected by cancer.
‘I lost a very good friend a number of years ago to cancer and I know lots of people who are recovering or suffering.
‘It’s something that touches everybody and that’s why you get the great crowds.’
Southsea resident Emma Steven, 32, agreed.
‘The atmosphere is amazing,’ she said. ‘I was running next to a lady pushing a pram, she really inspired me to keep going.
‘When you’re running and you think you might not have enough in you, you just think about all the people who have been through so much more and that keeps you going.’
