Ultra Trail Jeju

Ultra Trail Jeju:

Trans Jeju is the biggest ultra distance trail event on the volcanic island Jeju, South Korea. Participants will run through the Hallasan National Park (UNESCO World Heritage), which is extremely diverse: at various altitudes there are more than 1,800 species of subtropical, temperate and subarctic plants flourishing on the Halla volcano (the highest mountain in South Korea) that change distinctly with four seasons, offering runners ever-changing scenery. Surrounding the mountain’s peak is the world’s largest forest of Abies Koreana, which have become popular today as Christmas trees. This ultra offers majestic views, including the crater lake called Baekrokdam and Youngsil Giam, a cliff composed of weird-shaped rocks.

Trans Jeju offers three distances that climb the volcano Hallasan, 10km, 50km, 112km races. This is the longest trail running course in Korea with roughly 1,000 competitors from more than 30 countries in 2018.

The 112km Transjeju covers the most scenic trails of the Hallasan National Park on Jeju Island, for a cumulative elevation gain of 4,800 meters. This is a challenging trail run which requires adequate training to complete the full route within 30 hours. The route includes the steep climb of the Hallasan volcano (1,950m) with a breathtaking view of the crater. This race is semi-self sufficiency (9 refreshment posts are located along the route) with mandatory gear.

​To enroll for the Trans Jeju 112km, ​you must be a finisher of a 100km trail race OR of a 50km trail race in 12h within the last 2 years up until the day before the registration start date.
