Jeff Edwards, Managing Director of Asia for the IRONMAN Group, said: “Safety and accessibility remain our top priorities, and we’re grateful for the continued support of the public and our partners in delivering a world-class marathon experience for everyone. With a refreshed course and two-day format that celebrates Singapore’s cityscape and community spirit, SCSM 2025 offers runners the perfect stage to challenge themselves and achieve new personal bests.
