Unbreakable: The Western States 100, a feature length film about four mountain runners tackling the most prestigious 100 mile race in the world, has beaten stiff competition to be announced as the winner of this year's Sheffield Adventure Film Festival.
Now in its seventh year, the festival showcases some of the most extreme and adventurous films of 2011. Unbreakable: The Western States 100 intertwines tales of the race's evolution and the fierce competition the 2010 event witnessed with four undefeated ultrarunners all vying for victory.
Originally conceived as a horse race, the event was altered when one competitor - Gordy Ainsleigh - decided his animal wasn't fit enough to travel and resorted to covering the 100 miles on foot. Since 1977, the race has officially been for runners and takes place on the last Saturday in June.
Running parallel with this is coverage of the 2010 race, with ultrarunners Hal Koerner, Geoff Roes, Anton Krupicka and Kilian Jornet all looking to maintain their undefeated records. The film provides some excellent visual commentary of the route the men encounter, which includes a punishing cumulative ascent of 18,000 feet through the Sierra Nevada.
One of the Sheffield Adventure Film judges, Team GB duathlete Nikalas Cook, commented: "The 2010 Western States 100 was a perfect storm of a race with four of the greatest, undefeated mountain runners on earth fighting to win the oldest and most prestigious 100 mile foot race in the world. Even if you already know the result, it'll still have you on the edge of your seat right down to the final few miles."
