Race Courses

Race course not final – subject to change.


The city venue is an iconic location adorned with the most glitzy skyscrapers and unique architectural buildings in the world.

You’ll race on the same streets as the professional triathletes, the only difference is amateur athletes will have different length laps to provide an optimal mass-participation experience.

Spectators will be blessed with the opportunity to cheer their athlete multiple times each leg, while enjoying the festival activities and food and beverages. Bring the whole family and friends for an unforgettable weekend in a truly stunning location.

Key info


The run is on flat, paved surfaces and provides the most scenic view from within the heart of Singapore’s iconic skyline. Standard Duathlon competitors will take on one 5km lap, while Long Duathlon competitors will kick off with two laps for a total of 9.5km.

From transition, you will skirt the waterside, turning right to navigate around the ArtScience Museum and under the Benjamin Sheares Bridge before continuing to the turn-around point. Then it’s back towards the Marina Bay Sands Hotel to complete each lap.

During each lap, you will be able to top up with fuel and hydration at three aid stations per lap. At the end of Run 1, you’ll reach transition to ready yourself for the bike course.

The Bike

The bike course takes place on a 16km long, closed city circuit route starting and finishing at Marina Bay. The fast course is on smooth tarmac with low rolling resistance and is made up of two 16km laps for Standard Distance athletes (32km) and four 16km laps for Long Distance athletes (64km).

What sets this course apart from any other is the location – smack in the middle of the city with stunning views of Marina Bay and the city skyline. You’ll cycle past many of the city’s most iconic landmarks including the ArtScience Museum, Helix Bridge, Singapore Flyer, and Marina Bay Sands hotel as well as crossing the Benjamin Sheares Bridge.

The total elevation of the bike course is approximately 700m. Each lap has an aid station to give you the opportunity to top up on energy and hydration.
At the end of the bike you’ll return to the transition area to get ready for the second run.


After cycling, it’ll be time to test your run strength again with one 5km lap for Standard Duathlon competitors and two laps for a total of 9.5km for Long Duathlon athletes. You’ll be on familiar ground during the second run as it’s the same route as the first – a flat paved surface for blistering speed and that stunning view from within the heart of Singapore’s iconic skyline.

During each lap, runners will be able to top up with fuel and hydration at three aid stations per lap. At the end of Run 2, you’ll head for a grandstand finish fit for the world’s best professional athletes!
