The “Bulgarian Ultramarathons 2020” association is a non-governmental organization founded by passionate mountain and running enthusiasts, with a mission to develop outdoor sports, amateur sport, and mountaineering culture in Bulgaria. We have been organizing races since 2013, and we host two iconic ultramarathons — Persenk Ultra and Thracian Ultra. Guided by the motto “From friends to friends,” we create experiences with soul — for runners, volunteers, and spectators. We believe that sport unites, inspires, and builds community.
