Our Friday Night Video this week is the 2017 film of the Berghaus Dragon's Back Race. The documentary follows the highs and (often extreme) lows of five race participants. 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 rider unfolding around them and the stunning Welsh landscapes they travel through.

The legendary Berghaus Dragon's Back Race follows the mountainous spine of Wales from north to south. The 5-day race is 315 kilometres long with 15,500 metres of ascent across wild, trackless and remote terrain. The inaugural event was held in 1992, which was won by a team of Helene Whittaker and Martin Stone. Twenty years later, the race returned for the second time and has been growing ever since.
