Bulgaria’s wildest trail run: big vert, high technicality and long, 2000M altitude traverses in Pirin National Park.
Pirin Ultra 68km is a former Skyrunner World Series trail race held in September in Pirin National Park, Blagoevgrad Province, Bulgaria. The course covers 68 kilometres with 4,400 metres of elevation gain — a very spicy 64.7 metres per kilometre. Entry is €78 standard (€1.15 per kilometre), which makes it extremely affordable. The course is the 4th least flat trail race of 390 European distances tracked - barely 5 kilometres across the 68km distance is considered flat. The glutes and quads will burn on this one ladies and gentlemen. The race opens with a 14.8km, 1,580+ meter climb from Bansko (10.67% average gradient), crossing several ski slopes and traversing several high alpine summits. Among the summits is Vihren at 2,914m — the highest point in the Pirin range and the third-highest peak in Bulgaria. Take a look at the route profile - the course essentially consists of scaling three mountains, with the second major climb a real killer, averaging a 17.91% gradient Bansko is the start and finish; Sofia airport (SOF) is approximately 2 hours 12 minutes away. The race has run annually since 2016. It suits experienced trail athletes seeking a credentialed alpine challenge that doesn´t break the bank in Bulgaria's most demanding national park.
