The 2017 film focuses on the highs and lows of five participants as they set out to conquer The Dragon. Each of them has a unique and emotional story to tell of their battle against the enormous physical and mental challenges of the race. We also see the wider race unfolding around them and the stunning Welsh landscapes they travel through. Will they all make it? The legendary Berghaus Dragon’s Back Race follows the mountainous spine of Wales from north to south. This incredible 5-day journey is 315 kilometres long with 15,500 metres of ascent across wild, trackless, remote and mountainous terrain. It is the toughest 5-day mountain race in the world.
