Samantha Larkin is running the Morrisons Great South Run in memory of her mum, who died last year of a brain haemorrhage.
Sue Thornton collapsed and died in August 2014, three months after her 60th birthday.
Sam, 36, is taking on the world’s leading 10-mile running event in her memory to raise money for the Stroke Association, a charity close to her heart.
The charity uses money to fund research into the prevention and treatment of haemorrhagic strokes, as well as research into other strokes and the rehabilitation of people after they have suffered a stroke.
Sam said: ‘When mum passed away last year, the whole family were devastated.
‘We found out that some strokes are genetic. We’re still waiting to find out if that is the case here, but it could mean that all of the family are at risk of something similar.

‘It makes the Stroke Association’s research such a worthy cause to run for. They are a really good cause and help thousands of people.’
Sam, who lives in Southsea, will join up to 25,000 runners on the start line of the Morrisons Great South Run, which takes place in Portsmouth on Sunday, October 25.
She has been hard at work training for the event and completed the Worthing 10k run in June this year.
Joining her for the upcoming Great South Run is husband Graham Larkin, 34, and good friends Helen Blakeborough, 35, Ruth Blakeborough, 39 and Andrew Pirie, 38.
Sam said: ‘They’ll all be running for Team Sue on the day and we’ll have lots of support on the sidelines from more family and friends!’
The 10-mile route of the Morrisons Great South Run takes in landmarks such as the Spinnaker Tower and Portsmouth Historic Dockyard, and runners are kept motivated by bands on the run, ‘boost zones’ and thousands of cheering spectators.
Famous faces to take part this year include double Olympic champion sailor Iain Percy and comedian Hugh Dennis, while European 10,000m champion Jo Pavey will compete in the women’s elite field.
The Great South Run is the world’s leading 10-mile running event. As well as the 10-mile run on Sunday, October 25, there are 5k, Junior and Mini events taking place on Saturday, October 24.
