Now, five years on, Lucy is running in the Vitality London 10,000 for Meningitis Now to help raise awareness about the disease.
Lucy said her cousin was the “kindest, bubbliest, most wonderful girl”, who was only 19 years old when she died. “Family, friends, and loved ones were heartbroken,” she said.
Lucy, who said she was really close to her cousin, including holidaying with her in South Africa and Turkey, now wanted to do everything she could to help fight meningitis.
“I will support this until no-one ever has to suffer because of it again - I see my 10k in May as an amazing part of this journey.”
Although Lucy, who lives in London, has raced in one 10k before, she said that she was by no means an experienced runner.
“My training isn't going too badly, although I will admit I have been running more inside than outside because of the weather!” she said.
“I'm looking forward to it hopefully warming up a bit come March so I can train more outside as I much prefer it.”
