Lampang 100 Winter 2027

Lampang 100 Winter 2027 is a two-day trail and ultra-running event in Mueang Pan, Lampang, centred on the Pang Ma-Pang Lor area. The current registration programme schedules the long races on Saturday, 23 January, followed by the 20K on Sunday, 24 January. The event continues the Lampang100 trail series, which is also listed by the same registration platform in earlier 2024 and 2025 editions.

The headline 100K and 70K races both start at 05:00 on Saturday. The organiser gives them overall time limits of 30 hours and 20 hours respectively. The middle-distance race starts at 06:00 with a 12-hour limit, while the 20K starts at 06:30 on Sunday with a five-hour limit. Current registration material has one naming inconsistency for the middle race: the early-bird table calls it 42K while the regular-price table calls it 40K. ARC therefore does not force that course, the 70K or the 20K into an inaccurate structured distance.

The organiser's rules describe the course as natural terrain that also shares sections with local communities. Runners must stay on the marked route, must not use shortcuts, and are required to protect natural resources, buildings and agricultural areas and carry their rubbish rather than litter. The organiser reserves the right to alter, shorten, extend or cancel routes if conditions make continued racing unsafe.

Entrants must be at least 18. Bibs are personal and transfers are prohibited. Runners withdrawing during the race must do so at a rescue or service point and notify staff. Late starts more than 15 minutes after the official gun are not permitted. Race numbers and equipment must be collected personally before race day using government-issued identification; proxy collection and race-day collection are not allowed.

The current registration preview lists regular prices of THB 5,100 for 100K, THB 4,300 for 70K, THB 3,500 for the 40K listing and THB 1,900 for 20K. Detailed route maps, elevation profiles, aid-station locations, prize information and the exact race-pack collection schedule are not yet exposed in the current text source.

Live registration status and payment rules (checked 25 October 2026)

The organiser's current-edition registration checkout lists regular entry as OPEN for all four offered distances: 100K THB 5,100; 70K THB 4,300; the regular-price 40K category THB 3,500; and 20K THB 1,900. These advertised categories accept applications from 1 October through 31 December 2026 at 23:59 Thailand time, subject to available places or organiser changes. Earlier early-bird categories are CLOSED; their lower rates should not be used as current entry prices. The organiser's current checkout calls the middle distance 40K, while an earlier early-bird listing says 42K, so confirm the exact course distance with the organiser before paying.

Important booking conditions: entrants must be 18 or older and submit their own accurate registration details; duplicate or proxy applications are prohibited. The organiser says completed registration fees are non-refundable, name/bib transfers are not permitted, and a requested correction to registration details may incur a THB 500 administration charge despite the general no-changes rule. The published payment window is 72 hours, with an individual QR-payment code valid for 10 minutes. Always check the live checkout status, especially as capacity or terms can change.
