43-year-old Min Duchenski is trying to raise £2,000 for the event’s founding charity Walk the Walk.
Min, who was diagnosed with breast cancer in 2019, had what she’s describing as her “miracle baby” last year.
She’s walking as a symbol of hope to others that there is life after a breast cancer diagnosis.
This year’s MoonWalk London takes place on Saturday the 20th of May, starting at midnight on Clapham Common.
