Reach Your Limits(2015)

One of the best Bulgarian mountain runners – Kiril Nikolov, known as Disl, attempted to set a new record – to run through the longest and legendary Bulgarian mountain route – 600 km from the mountain peak of Kom on the west border to cape Emine on the Black Sea coast, in less than 5 days. Through steep mountain paths, pouring rain, and sticky mud, the glorious adventure takes him beyond the barriers of his own consciousness, facing hidden fears, pain and exhaustion. Tо the point where he has to make a tough choice – to quit or to push his will to the ultimate challenge, beyond his own limitations.
