Trans Jeju by UTMB : Route, live tracking & how to enter

Trans Jeju by UTMB is one of the biggest ultra distance trail running events in Asia, situated on the volcanic island of Jeju in South Korea. Runners across all four races will take in the stunning views of Hallasan National Park, a UNESCO World Heritage site, and climb South Korea’s highest mountain, Mount Hallasan.

The two-day programme of races joins the UTMB World Series for the first time in its ninth running. Runners competing in the Jeju100K category will earn three UTMB running stones – which earn entry to the lottery for the UTMB finals at the Ultra-Trail Marathon du Mont-Blanc.

The Jeju50K event sees competitors earn two running stones, and Jeju20K runners earn one running stone.

Here is our full guide to learning about this UTMB World Series event, following it live or even taking part.

Trans Jeju by UTMB Route

The organisers have set a course through the UNESCO World Heritage site of Hallasan National Park, centered around Mount Hallasan, the highest mountain in South Korea.

The 111km course covers some of the most scenic trails of the National Park, with a cumulative elevation gain of 4,200 metres. The route includes a steep climb up the Hallasan Volcano (1,950m) with a breathtaking view of the crater.

The 56km course includes 2,500m of cumulative elevation and again includes the climb up Hallasan Volcano.

“One of the biggest draws of TransJeju by UTMB is that runners can reach the peak of the Hallasan Mountain,” race director Byeungsik Ahn said.
