After supporting her brave sister in her battle with a rare condition Dr Kate Couchman knew that she needed to do something special.
And that something is take on three of the UK’s most gruelling challenges, in an effort to raise funds and awareness of her sister Meg’s life-threatening illness myasthenia gravis.
Kate, 35, moved from South Africa to Kerr Place, Aylesbury in 2011, to take up a medical advisor role at Solgar Vitamins and Herbs in Tring.
This year she will take on the Three Peaks, Thames Path 100km and Grand Union walking challenges in aid of the Myasthenia Gravis Association.
She said: “I’m doing it because I need to keep myself busy, I feel so useless being here.
“I want to raise as much awareness as possible so I am doing something that I will find very gruelling.
“If I went skydiving or something that’s just fun, that would not push me to the limit and I wouldn’t feel right about asking people to donate money.
“For her 21st birthday Meg came out of hospital. She was not feeling well but she said: ‘I will do it’ and she did.
“She is absolutely gorgeous, so many people might sit there feeling sorry for themselves but she has this amazing fighting spirit.”
Aged just 15 Kate’s sister Meg was diagnosed with the condition, which affects the muscles in her throat making it difficult for her to eat or speak.
Meg is now 25, and has recently been re-admitted to hospital for further treatment.
Her lifelong dream of having children also lies in the balance, as rounds of treatment may have affected her fertility.
