Climbing mountains is in Sequoia Schmidt's DNA.
She's the daughter of famous mountaineer Marty Schmidt and grew up surrounded by crampons and ice axes.
Four years ago her family paid the ultimate price for their hobby.
Her dad and brother were killed in an avalanche on K2, the second-highest mountain in the world.
In one single moment she lost half of her family, but that one moment has shaped every other one since.
She travelled to K2 to find her family, written an award-winning book called Journey of the Heart and she's about to embark on a nationwide bike tour.
She spoke to Duncan Garner.
