The Si Chang Scenic Trail is a trail running event set in the natural landscape of Koh Si Chang. The course takes runners across hills, coastal cliffs, forest paths, and seaside viewpoints, offering a running experience shaped by the island’s terrain rather than speed alone.
This event is designed for runners who enjoy outdoor challenges and running in nature. Instead of city roads, the route passes through quiet forests, hidden beaches, and elevated paths with open sea views, creating a strong connection between sport and scenery.
The event is organised by Road Runner Thailand, a well-known name in Thailand’s running community, and attracts runners looking for a unique island trail experience in Chonburi province.

Koh Si Chang is well-suited for trail running thanks to its small size and varied natural landscape. The island covers just 18 square kilometres, yet offers many different routes and surfaces within a short distance from the mainland.
Together, these features make Koh Si Chang a rewarding location for runners who enjoy nature, scenery, and a peaceful island running experience.

The Si Chang Scenic Trail takes place on Sunday, May 31, 2026, on Koh Si Chang in Chonburi province. Main event activities are held around Phra Chuthathut Palace, one of the island’s key landmarks.
