The Transylvania 100 comprises five different races, of varied distance (100, 80, 50, 30 and 20 kilometers), in the Bucegi Mountains region. Each race is a single stage only for solo runners within the specified time limits. The routes, checkpoint locations and altitude gain for each race can be found in the Races section of this website.
All five races have a basic principle of self-sufficiency while mountain-running, this being defined as the competitor's ability to be self-sufficient between two checkpoints not only in terms of feeding and hydration but also in terms of clothing, equipment and personal security.
The Transylvania 100 races are inspired and follow the principles and values promoted by the International Trail Running Association (ITRA):
- equity for all competitors;
- respect in all its forms, from self-esteem, to the other contestants (competitors, volunteers, locals, etc.) and to the environment;
- solidarity with those in difficulty - other competitors, volunteers or spectators.
