Family and friends will run together to pay a lasting tribute to the memory of a Bognor Regis teenager.

Forty family and friends of 19-year-old David Green, who died last December from an undiagnosed hereditary heart condition, will pull on their running shoes and take part in Sunday's 2011 Bognor Prom 10K Race.

Dubbed ' Team David', the runners have already raised £2,000 in sponsorship for Cardiac Risk in the Young (CRY). 

David's mum Gabby Broadhurst said: "We are running the Bognor 10K to raise money for Cardiac Risk in the Young, in memory of our beloved son David Green. 

"David was a healthy and fit 19-year-old, who loved to play hockey and football.  He had run the Bognor 10K on several occasions himself. 

"David's death has left our family devastated and truly shocked, to lose a child is any parent's worst nightmare. 

"If we can prevent another family from experiencing such a tragedy then our son's death takes on some meaning." 

CRY conducts research into the causes of heart problems, and aims to reduce the frequency of young sudden cardiac deaths. 

Gabby said: "As a family we were unaware of the statistics of sudden arrhythmic death, and that apparently 12 fit and healthy young people die each week.  This figure can be greatly reduced if young people are screened. 

"It was only through heart screening due to David's death, that sudden arrhythmic death syndrome was diagnosed in another family member. 

"As a family we will continue to raise awareness and raise money for CRY.  Young people are dying needlessly and it is important this message is heard." 

Sunday's fundraising effort is the latest in a series of events David's family and fiends have been involved with. 

Gabby said people have been amazing in their endeavours to raise money for CRY. 

"A friend, Matt Minter, did a bungee jump in Switzerland at Verrzasca Dam. which at 722 feet in the highest jump in the world and raised £1,000 over the weekend. 

David's sister, nieces and nephew did a sponsored walk and raised £300. 

"I will be running in the Great North Run as part of the CRY team and hope to raise even more," said Gabby. 

In April the Middleton and Bangor Hockey Club hosted a charity afternoon which raised £2,000. 

David was a midfielder for the club and had played the sport since he was 11. 

the Bognor Prom 10K, which is in its 17th successful year will start in West Park in Aldwick at 11.30am.
