Run only once before, in 1992, the Dragon's Back Race became legend for its 300 kilometres of relentless, brutal mountain running down the spine of Wales. Returning for its twentieth anniversary, this film takes you into the heart of an inspiring, punishing adventure as 84 competitors weave a precipitous path along the mountainous ridge.

Why This Film Matters: The great endurance races are as much about the mind as the legs, and the Dragon's Back pushes both to the edge over days rather than hours. This is a story of perseverance and reckoning, of ordinary people discovering what they are capable of when the terrain refuses to relent, and of a race whose myth was worth reviving.
