Gauja Trail by UTMB 86 km is a trail race held on August 1–2, 2026, in Gauja National Park, Vidzeme region, Latvia — part of the official UTMB World Series circuit.
The course covers 86 km with 2,000 m of gain (23.3 m/km) through Baltic pine forest, sandstone gorges, riverside trails, and past medieval castle ruins in the Gauja river valley. This is one of the flattest major ultras in the DTR database: 47.6% of the course is flat terrain, with the biggest single climb rising just 76 m. The race demands sustained aerobic running rather than technical mountain skills. Entry costs €149 standard (€1.73/km) — note the UTMB registration platform adds €11.92 per participant (€161 effective).
Riga (RIX) airport is 114 minutes by road; direct trains from Riga to Sigulda and Cēsis make this unusually accessible by public transport. Launched in 2020 and now a UTMB World Series qualifier for UTMB Mont-Blanc, drawing 195 finishers in 2024. It suits endurance-focused trail runners who want UTMB qualifying points in a summer forest setting without the technical hazards of alpine terrain.
