Phuket Sports Events and Races: Laguna Triathlon, Marathon and Trail Runs
Phuket has a busy race calendar, mostly around Laguna in the north. This page summarises reports and event pages. Dates, distances and fees change each year, so confirm with the organiser before you enter. Reviewed in November 2026.
Laguna Phuket Triathlon
The triathlon is described as Asia's longest-running, with a unique race of a 1.8 km swim, 55 km bike and 12 km run, plus shorter formats such as a sprint, duathlon and relay. The 31st edition was held on 23 November 2025 with more than 1,000 athletes. A Phuket expat guide quotes entry of roughly 5,000 to 7,000 baht, but fees change.
Marathon and trail running
The Laguna Phuket Marathon has run since 2006, usually around June, with a full marathon, half marathon, relay and short distances, and is listed as a Boston Marathon qualifier. The Andaman International Trail Running event was held on 29 June in one year and drew over 1,000 runners. Smaller community runs and mini-marathons also take place.
Joining in
Training season is described as roughly October to April, with group swims at Bang Tao and Nai Harn and a Phuket triathlon Facebook community. See the running and cycling guide, the gyms guide, the physiotherapy guide and the festivals calendar.
