Cluj EcoTrail 50km: Romania's National Day Ultra, Measured

Accessible to experienced trail runners rather than elite-only. The course covers 50km (UTMB-measured 52km) with 1,720m of gain — approximately 34m per kilometre — and is described by the organisers as suitable for a first ultramarathon. The terrain is largely runnable forest trail with one main ascent to the Feleacu plateau. The challenge is primarily the December 1 conditions: sub-zero feel-like temperatures, muddy or icy forest trails, and potentially limited daylight for slower runners. Time limit is 9 hours.

December 1 is Romania's National Day — Ziua Marii Uniri (Great Union Day) — commemorating the 1918 unification of Transylvania with Romania. The race is held on this date every year, and each runner chooses to represent one of Romania's nine historic regions. In 2026 it will be the 9th edition.

230 RON (approximately €46) at the standard price, valid until September 30, 2026. At €0.92 per kilometre, it is among the most affordable UTMB-indexed 50km races in the DTR database. Optional extras — T-shirt, socks, refund insurance — are each available for 19 RON.

Cluj-Napoca International Airport (CLJ) is 17 minutes from the race start at Baza Sportiva Gheorgheni by road — one of the shortest airport-to-start transfers in the DTR database. The city has excellent public transport (tram, bus, taxi). Accommodation is plentiful in Cluj-Napoca; book early as December can be busy.

Yes — the Ultra 50km is listed on the UTMB Index and awards 2 ITRA points. The 2025 edition had 322 finishers from 22 countries.
