SWIMATHON 2025 Presented by TriFactor "Bring it back"

20 - 21 December 2025
Chon Buri province :: Na Jomtien Beach area (in front of the Zand Morada Hotel Pattaya), Sattahip District

"The return of Thailand's most famous swimming event" A new era of happiness and fun has begun. The stadium with the first identity that stimulated Endurance enthusiasts to be more interested in swimming in the sea. In late 2016, Thailand became more familiar with the sport of swimming in the sea, or what is known as Open Water Swimming. The course opened with a group of over 700 triathletes, runners and swimmers in the pool. A simple course, Na Jomtien sea, a swimming route not far from the shore. There was time to rest, drink water, snacks, refill energy gels, and receive cheers from the audience and family along with the excitement of exciting music that gave me the energy and motivation to return to the field for the next round until the challenging distance was completed. It also promotes swimming activities for youth with the final round of the AMAZINGKIDS SWIM SERIES on December 20, 2025, which is an event that starts the competition throughout the year to collect points at the last field to announce the Series Championship Winner of the youth group aged 6-17 years, the 100-meter, 200-meter, 400-meter, 800-meter and 1,200-meter races.
