COURAGEOUS Hannah Barrett had already been through months of chemotherapy when she swam a four mile section of the English Channel.
She was battling a brain tumour when she completed the challenge to raise money for the charity she helped set up.
Last July, she lost her two-year battle against the cancer, having raised thousands for the Latin American Foundation for the Future.
But her legacy lives on after her boyfriend Henry Channer raised £3,000 for LAFF by completing the London Marathon last week. Now her younger sister Faye will tackle the Edinburgh Marathon on May 22 in aid of the Samantha Dickson Brain Tumour Trust.
Mum Merilyn, from Dorridge, said Hannah had studied languages and was very passionate about overseas work.
“She had been living in Peru and helped set up this charity to support children living in some of the most deprived areas.
“In 2009, she was determined to take part in the English Channel challenge, but she didn’t think she would be able to do it.
“After a third operation they managed to seal the hole in her skull and she was so excited, she was straight back in the team. There were six of them doing it in a relay, Hannah swam four miles through the cold water and currents - it was remarkable.”
The challenge raised £12,000 for LAFF and that summer, Hannah found out she’d landed her dream job with the Volunteer Service Overseas.
Tragically, the tumour became more aggressive again, her condition deteriorated and she died last year - aged just 26.
“Hannah never complained and almost treated the tumour as an inconvenience,” added Merilyn, who teaches at Solihull School.
