Susan Taylor, a 34-year-old British woman, died Sunday during a charity swim across the English Channel, according to a post on her Facebook page.
"Whilst attempting to swim the English Channel yesterday my sister, Susan collapsed suddenly in the water. She was immediately recovered from the water and treated on the support boat. She was then air lifted by helicopter to a hospital in Boulonge. Susan tragically passed away. Thank you for your messages of support. Please respect the families privacy whilst they come to terms with what has happened. If you would like to leave a sign of respect please feel free to donate to her fund raising page."
Taylor reportedly collapsed near the end of a 21-mile crossing form England to France at around 5:30 p.m.
Taylor had organized and self-funded the charity swim across the English Channel to raise funds for Rainbows Hospice and Diabetes UK, an organization "where life-limited children and their families can find care and support."
She had raised a little over $4,000 up until news of her passing broke, at which point donations soared to more than $73,000, according to the Independent.
In a a post written in Taylor's fundraising site, she explained that "less than 1,000 people have completed the 21-mile cross-Channel swim." She had intended to complete the crossing alone, but accompanied by a support boat that would ensure she "out of trouble."
