Singapore T100 Triathlon takes place on 10-11 April 2027 at Marina Bay, Singapore. The organizer is T100 Triathlon (PTO), and registration runs through the event's participate page.
The 100km Triathlon consists of a 2 km swim, 80 km bike and 18 km run. Teams of 2 or 3 can enter the relay option and split the three legs between them. The Sprint Triathlon is shorter: a 750 m swim, 20 km bike and 5 km run.
The organizer's 2026 athlete info lists the swim in the Marina Bay reservoir, an undulating bike course and a flat run. Water temperature was given as 25-28°C and air temperature as 26-34°C. These figures come from the 2026 edition. All T100 Triathlon events are qualifiers for the Qatar T100 World Championship Finals.
