A top Suffolk sportswoman has backed a campaign to get teenagers life-saving health tests at her school.

World bowls champion, Katherine Rednall, 18, was in the same textile class at Stowmarket High School as Lily Webster who died in 2012 after collapsing during a trampolining class.

The 15-year-old had a rare heart condition which she and her family were not aware of. Since then her family has raised thousands of pounds for the charity Cardiac Risk in the Young (CRY).

A chunk of the money – £7,000 – was needed to organise two days of heart screening for young people, aged between 14 and 35, in July.

Now Lily’s mother, Melanie Webster, has offered Katherine the chance to be screened.

“Obviously what happened with Lily was a massive shock, nobody knew anything about it,” Katherine said. “It was a normal day and it all happened very quickly. It’s definitely important to get young people tested. The screening is so expensive it seems ridiculous how much it is considering how important it is.”

The screening is being offered to 100 people each day at the school on July 1-2. Those interested need to book in advance.

The Webster family is campaigning to raise the awareness of Sudden Adult Death Syndrome (SADS) – a condition which, if not treated, can result in a dramatic and often spontaneous death.

Last month a leading cardiologist said the number of young people who are dying each week from SADS is significantly higher than current estimates.

Katherine became the youngest-ever bowls world champion in January. She is now looking to go on a sports apprenticeship course in the summer and has aspirations to become a PE teacher.
