In marking the 10th edition, the triathlon, themed as ‘A Decade of Triumph-where every finish line is a new beginning’, embodies the remarkable resilience, ambition and global connection that has propelled Việt Nam into a premier destination for endurance sports.

Six-time IRONMAN World Champion and one of the sport's most inspiring pioneers, triathlon legends Mark Allen, and Yee Sze Mun, the 88-year-old Malaysian icon and Hall of Fame Inductee, continue to redefine the limits of age and endurance.

The sport in Việt Nam has exploded in popularity over the past decade with this year attracting 1,900 Vietnamese athletes to the full distances. The country debuted the event with 54 athletes at the inaugural event in 2015.

The 2025 edition also marks a major technological leap for the event integrating for the first time ever Mixed Reality (MR) technology through a pioneering partnership with immersive tech company tagSpace at the IRONMAN 70.3 Da Nang.

We are proud to continue our partnership with IRONMAN and remain committed to providing the strongest possible support to help the event grow into one of the most distinguished sporting competitions in the Asia-Pacific region.”

The CEO of Minh Long company Lý Huy Sáng, said: "We are honored to take on a new milestone as the Presenting Sponsor of IRONMAN 70.3 Da Nang. We remain committed to preserving and promoting enduring values, ensuring that Vietnam’s identity and aspirations continue to shine brightly on the global stage."
