Samui Trail returns to Koh Samui on 7–8 November 2026, bringing runners onto the island’s inland trails for a weekend of off-road racing. With distances ranging from 7 km to a 55 km ultra, the event offers options for shorter-distance runners as well as those looking for a more demanding challenge.
The race is associated with the 4KINGs Plus Southern Thailand Trail Series and is organised by Samui Trail Plus.

Running Koh Samui’s inland trails
Unlike road races around the island, Samui Trail takes participants into the hills and tropical forest, with uneven terrain, climbs and scenic views along the way. The 55 km course is the major endurance challenge, while the 7 km, 15 km and 25 km distances provide shorter alternatives.
Trail running requires more preparation than simply turning up in running shoes. The organiser’s published equipment guidance includes a hydration pack with at least 1.5 litres of capacity and a reusable cup. Headlamps and additional safety equipment are required for some distances, so participants should check the complete requirements for their chosen race before setting off.
