Pirin Ultra 160km: Bulgaria's GPS-Only Hardrock Qualifier, Measured
Pirin Ultra is a 160-kilometre trail race held in September in Pirin National Park, Blagoevgrad Province, Bulgaria.
The course gains 11,000 metres of elevation — 68.75 metres per kilometre — placing it among the most elevation-dense 160km events in Europe. Entry costs €98 standard (€0.61 per kilometre), which for a race of its seriousness, is remarkably affordable.
The route is entirely unmarked. Runners carry the official GPX file and navigate across the high Pirin mountains, summiting Vihren (2,914m) and traversing exposed limestone ridges between Bansko and a chain of remote alpine huts.
The most dangerous section — km 45–55 — crosses marble ridge terrain with no water, no marking, and proximity to vertical rock walls, often in darkness for mid-pack runners. A 50-hour cutoff guarantees all finishers experience at least one full night on high-altitude terrain. Just 9.7% of the course is flat: the 160km is effectively split in half between climbing and descending.
Bansko is the start and finish; Sofia airport (SOF) is approximately 2 hours 12 minutes away. First held in 2016, Pirin Ultra is a UTMB 100M qualifier and a Hardrock 100 qualifier. With 87 confirmed finishers in 2024, it is recommended for highly experienced mountain runners who are looking for a wild experience - equally comfortable with autonomous navigation and sustained exposure.
