B-Quik Khao Yai Marathon 2027

B-Quik Khao Yai Marathon 2027 brings runners to Mu Si in Pak Chong District, on the edge of Thailand's Khao Yai World Heritage landscape. The established road-running event is listed by AIMS, while World Athletics' certified-road-race register includes the Khao Yai Marathon and Half Marathon courses with certification extending to 2029. The programme caters for experienced marathoners through to families, with 42.195K, 21.1K, 10K, 5K and 2K events across the weekend.

The main races use paved roads around Mu Si and Khao Yai, giving the event a markedly different character from a city marathon. The setting is known for forest, nature and wildlife, and the event promotes the chance to combine running with a visit to the Khao Yai area. The marathon and half marathon are single-loop road races according to current race listings.

The 2027 event runs across Saturday 9 and Sunday 10 January. The 2K is scheduled for Saturday afternoon, while the marathon, half marathon, 10K and 5K take place on Sunday morning. Current event information lists Sunday flag-offs at 03:00 for the marathon, 04:30 for the half marathon, 05:00 for the 10K and 05:15 for the 5K, with the 2K scheduled for 16:30 on Saturday.

Participants should check the organiser's final race guide before travelling, particularly for transport, parking, baggage, hydration, cut-offs and any late programme changes. Khao Yai is a destination event rather than a central-city race, so runners travelling from Bangkok or elsewhere should allow extra time for accommodation and access to the Mu Si start area.
