Jenny Tough is an endurance athlete who's best known for running and cycling in some of world's most challenging events – achieving accolades that are an inspiration to outdoor adventurers everywhere. But SOLO tells the story of a much more personal project: Jenny's quest to come to terms with feelings and emotions that were holding her back.

Like runners at any level, she knew already that running made her feel better, and like so many of us, she knew that completing goals independently was empowering, too. So she set herself an audacious objective: to run – solo, unsupported, on her own – across mountain ranges on six continents, starting with one of the most remote locations on Earth in Kyrgystan.

SOLO chronicles Jenny's journey every step of the way across the Tien Shan (Asia), the High Atlas (Africa), the Bolivian Andes (South America), the Southern Alps (Oceania), the Canadian Rockies (North America) and the Transylvanian Alps (Europe), as she learns lessons in self-esteem, resilience, bravery and so much more. What Jenny's story tells us most of all is that setting out to do things solo – whether the ambitious or the everyday – can be invigorating, encouraging and joyful. And her call to action to find strength, confidence and self-belief in everything we do will inspire and motivate.
