Phu Wiang Trail 2027 - Khon Kaen, Thailand

Phu Wiang Trail 2027 marks the event's fifth anniversary with two days of trail running through Phu Wiang National Park in the hills of Khon Kaen province, north-eastern Thailand. The national park is famous for dinosaur fossils as well as rugged woodland and scenic ridgelines. Six distances range from an accessible 5 km fun run to a demanding 111 km ultra. The organiser expects a field limited to 800 runners in total.

Official race starts (Thailand time, ICT, UTC+7)

• Saturday 6 February: 111 km Ultra Trail at 04:00, with 27 hours allowed to finish on Sunday morning. The course advertises approximately 2,663 m ascent and a 100K UTMB Index classification.
• Sunday 7 February: 62 km at 03:00 (14-hour limit, about 1,718 m ascent); 38 km at 04:30 (8-hour limit, about 884 m ascent); 22 km at 05:00 (5-hour limit, about 511 m ascent); 11 km at 05:30 (2 hours 30 minutes, about 328 m ascent); and 5 km at 06:00 (about 184 m ascent).
• The 62 km, 38 km and 22 km courses also have intermediate checkpoints with earlier cut-off times. For example, 62 km participants must reach the first cut-off by 08:30, and 38 km runners by 11:00 on Sunday. Check official GPX maps and the full aid-station/checkpoint rules before selecting a distance.

The 111 km, 62 km, 38 km and 22 km distances are the organiser's actual advertised distances, not interchangeable with 100K, 50K, marathon or half-marathon standard categories. ARC currently has exact distance selectors only for the 11K and 5K of these six options; the other four are documented here rather than incorrectly labelled in the category filters.

Registration and inclusions

The live official Runlah entry page, checked on 4 November 2026, now displays Register now and all six priced entry categories. Registration is open, subject to remaining places. The advertised early-bird period runs until 22 December 2026 at 23:59 ICT, subject to availability; general prices increase thereafter. The organiser's full six-distance fee table is 111K THB 5,190 / 5,690, 62K THB 2,890 / 3,490, 38K THB 1,790 / 2,290, 22K THB 1,590 / 2,000, 11K THB 1,290 / 1,790, and 5K THB 890 / 1,190 (early-bird / regular). Verify the payable tier and remaining places at checkout.

All entries advertise a race shirt, bib, medal, refreshments and accident insurance; qualifying finishers in the longer four races also receive a distance-specific finisher shirt. The 5K is non-competitive. Age-group awards are offered across 11K to 111K, plus overall awards for the longer distances, but no cash prizes.

Trail safety and race-day practicalities

All six routes begin and finish within Phu Wiang National Park. Mandatory kit: for every distance from 11K upwards the organiser requires at least 1 litre of carried water, a reusable cup, whistle and headlamp. Runners in 38K, 62K and 111K must also carry food, a basic first-aid kit and their route map on a watch or phone; the 111K requires a mobile phone. The 111K has an additional qualification requirement: age 18+ and evidence of at least two 50K+ trail finishes or an eligible full marathon completed within its cut-off, submitted to reflect245@gmail.com or LINE @reflect. Read the full course maps and mandatory-kit matrix and allow time for mountain travel. Organisers may change a course due to hazardous natural conditions. Race numbers cannot be transferred, sold or lent, and the registration terms prohibit voluntary refunds. Race-day baggage deposit opens at 03:00 Saturday for the 111K and 02:00 Sunday for the other races. BIBs and event shirts are supplied by post only; the organiser says there is NO in-person race-pack collection. Supply a full postal delivery address when entering, and confirm any international shipping arrangements with the organiser. The map coordinates identify the national park generally, not a surveyed start arch.
