About SIT


The Singapore International Triathlon (SIT) is Singapore’s pioneer triathlon event. Established in 1984, it was launched in an era when triathlons and endurance sports in general were largely unknown in Asia. From the first local triathlon held by the National University of Singapore (NUS) in its campus, it evolved into an international event two years later with a wide diversity of athletes participation from multiple countries including Malaysia, Hong Kong, New Zealand and Australia.

Through the years, the number of participants has grown steadily. The race distances of 2km swim, 65km bike and 16km run, were also changed to the widely accepted Olympic distance. During this time, local sportsmen have also achieved elite competitive status through better knowledge in training and sports conditioning.

Today, the SIT has become one of the most highly-anticipated, international sports events in Singapore. Co-organised by Triathlon Association of Singapore and Orange Room Pte Ltd, the event has attracted up to 3,000 triathletes from countries such as Ireland, Italy, Sweden, France, Spain, USA, Canada, Belgium, Germany, Switzerland, Austria, Denmark, Australia, New Zealand, South Africa, Japan, Indonesia and Malaysia, who vied for various coveted championship titles, including the Asian Championship.

Held at the East Coast Park, this is a great opportunity for participants to Race the Lion City. The event boasts warm and calm water, scenic location, well-marked course and friendly volunteers, promising a memorable racing experience for all to enjoy from the starting to the finishing line.


Named the No.2 Ultimate Sports City, Singapore has developed a buoyant sports culture. It has hosted a number of international marquee sporting events such as the inaugural Youth Olympic Games in 2010, the annual F1 night race and the 28th Southeast Asian (SEA) Games in 2015, placing the city-state on the international map for sports.

Overseas participants will also have an excellent opportunity to experience the exciting things the tropical island has to offer after the race. They can savour the renowned and diverse culinary cuisines in this food paradise, be awed by the green spaces such as the iconic Gardens by the Bay and the Botanic Gardens, (recently inscribed as a UNESCO World Heritage), and immerse in cultural hotspots such as Chinatown, Little India and Geylang Serai. Most of all, participants can enjoy the shopping, theme parks, museums and popular night spots that will sure to stimulate their senses!
