.@StephenNolan speaks to inspirational cancer survivor who is to climb four of Ireland's highest peaks in 24 hours - doing it on crutches! #BBCNolan

Already a survivor of a rare form of cancer, Letterkenny woman Nikki Bradley is determined to cram as much adventure in to her life as possible 

She's done some incredible things in her life already - but Nikki's next challenge is to climb four of Ireland's highest peaks in 24 hours - and she will be doing it on crutches. 

For Nikki it is a way of raising money for cancer charities. What's more, it is also her last big challenge before she has her right leg amputated.
