Course Details and Participation

Running the Mahasamut Trail requires high self-sufficiency and strict adherence to environmental and safety protocols.

• - The Terrain: The route consists of coastal trails and public roads. As roads are not closed for the event, participants must conduct themselves as regular road users and remain vigilant of traffic.
• - Navigation: Runners are responsible for finding their way using ribbon markings and provided course maps. If a runner strays, they are expected to navigate back to the trail independently.
• - Community Respect: The trail passes through residential areas and huts; runners are requested to maintain a low noise level and avoid damaging crops or local properties.
• - Visibility: To ensure safety along public road sections, the organizer strongly recommends wearing brightly colored shirts to remain visible to drivers and staff.

Registration and Fees

Registration is managed through a tiered pricing system, encouraging early commitment for the limited 750 available slots.

• - Early Bird Price: 2,200 THB for the first 150 participants who complete both registration and payment.
• - Regular Entry: 2,490 THB from slot 151 through March 19, 2026.
• - Late Entry: 2,690 THB for any remaining slots between March 20 and April 14, 2026.
• - Age Requirement: Participants must be at least 15 years old (calculated as 2026 minus the birth year).

Safety and Mandatory Equipment

A "Safety First" approach is strictly enforced, with mandatory gear checks and medical oversight throughout the duration of the event.

• - Mandatory Gear: Participants must carry all required equipment; failure to present items during random checks will result in immediate withdrawal from the race.
• - Sustainability: Plastic cups will not be provided at aid stations. Runners must bring their own hydration vessels to fill at checkpoints.
• - Bib Placement: Race bibs must be attached clearly to both the front and back of the upper body. Bibs should not be placed on shorts or altered in size.
• - Medical Authority: Race doctors and officials have the power to retire any participant deemed unfit to safely continue. Retired runners may still access finish line facilities.
