Ulleungdo Island International Trail (UiiT) 2027

The 2027 Ulleungdo Island International Trail (UiiT) takes runners across the mountainous volcanic landscape of Ulleungdo, in the East Sea off South Korea's east coast. Organised by OSK Outdoor Sports Korea, this destination race starts at Ulleung County Public Stadium and uses trails around the island's dramatic coastline and peaks. Entries are limited to 300 participants.

Courses and cut-offs

The 16 km course, introduced for 2027, gives newer trail runners a more manageable way to explore the island. It has a five-hour completion limit. The 40 km course is considerably more demanding, with an 11-hour limit and a substantial sea-to-summit climb of approximately 1,000 metres highlighted in the organiser's promotion. Expect steep climbing and descents, rocky natural trails and potentially changeable island weather. The organiser advertises a 07:00 local start on Sunday 18 July 2027. The actual race distances are 16 km and 40 km, rather than a 15 km race or a road marathon. All times are Korea Standard Time (KST, UTC+9).

Four-day travel programme

The standard itinerary begins at Pohang's Yeongilman Port on Friday 16 July, with the Ulleung Cruise departing at approximately 23:00. Passenger boarding is advertised around 21:20–22:30. Arrival at Ulleungdo's Sadong Port is scheduled for approximately 06:00 on Saturday 17 July, ahead of a day for sightseeing and race preparation. Sunday 18 July is race day. The organiser lists a return departure from Sadong around 12:20 on Monday 19 July, reaching Pohang approximately 18:40. Ferry timetables are subject to change; verify travel arrangements directly with OSK before booking separate connections.

Package inclusions and extra expenses

The organiser lists the 16 km package at KRW 549,000 and the 40 km package at KRW 599,000. Confirm availability and any optional charges with OSK before payment.

The advertised standard full package includes return Pohang–Ulleungdo cruise transport, two resort nights in shared triple accommodation, entry, race bib, branded trail-running souvenirs, checkpoint snacks, finish refreshments and a race-day shuttle bus. Personal travel insurance, most meals, travel to and from island ports and optional excursions are not included. OSK also promotes independently booked Dokdo cruises, diving and island sightseeing. Runners are generally limited to one bag, at most 70 × 40 × 40 cm or 60 litres, when using the organiser's travel arrangements. The exact transport and hotel terms should be confirmed before payment.

Compulsory kit and safety

The organiser's mandatory equipment list includes trail-running shoes, a running vest, windproof jacket, water bottle, mobile phone, survival blanket, headlamp, personal snacks, whistle, soft cup, cash and payment card. Both routes demand trail skills, but the longer race in particular requires experience with steep and potentially exposed terrain. A travel insurance policy suited to trail running is sensible, particularly because the organiser excludes personal insurance from the package.

Refunds and booking conditions

Under the organiser's published cancellation schedule, withdrawals by 31 December 2026 receive a full refund, those up to 31 May 2027 incur a 10% deduction, and withdrawals up to 20 June 2027 incur a 30% deduction. No refund is offered from 21 June 2027. OSK separately warns that cancellation due to disasters or emergencies may not be refundable. Accommodation assignments are due after 12 July, with optional paid room adjustments available from late June. Runners should consult the official 2027 information for the current terms and race briefing.
