A film about the effort of the mountaineer Doichin Boyanov, who on April 14 this year circumnavigated Vitosha by land, air, water, even underground, accompanied by some of the most successful and popular Bulgarian athletes.
The relay supermarathon was part of the initiative "Aday on Vitosha". The cause of the campaign is charitable - for people with physical disabilities. And the goal - to show the huge opportunities for sport in Vitosha and to raise funds for the construction of a path and a sports ground for people with disabilities in the mountain.
