After winning three paralympic medals, hand-bike racer Karen Darke is tackling a long ride on every continent. It's part of her Quest 79, an ambitious project bringing together sporting and bikepacking, hoping to recruit others to tackle their own Quest 79 projects.
We spoke over Skype with Karen in Majorca where the Spanish authorities have locked down hard.
Karen's website, including Quest 79 and Pole of Possibility is KarenDarke.com
