Singapore Triathlon
Race the heart of Singapore's skyline in a T100 triathlon that blends sheltered harbour swimming, city-road cycling, and a waterfront run — all under a tropical sun.
Where it is
Singapore, Singapore
Is this your race?
This is a serious, aspirational race best suited to athletes who already have open-water experience and a solid multi-sport base. Beginner fit 1/5: T100 baseline 2, −1 for typical race-day heat above 28 °C — no verified add factors apply.
✅ You’ll love it if…
- You have completed at least one Olympic-distance triathlon and want your next big challenge
- You thrive in heat and have trained in warm, humid conditions
- You have logged open-water swims and can document two qualifying events since January 1, 2025
- Racing past the Marina Bay Sands skyline is on your bucket list
⏳ Build up first if…
- You are brand-new to triathlon — start with a sprint or Olympic event first, then return to this one
- You have not yet completed open-water swim events, as the 2027 rules require documented qualifying swims
- You are not yet comfortable training in heat and humidity for multiple hours
- You are still building your cycling base beyond 60 km long rides
Not yet? That’s normal. Start here → take the 2-minute Readiness Assessment.
The course, demystified
The entire race unfolds in and around Marina Bay — Singapore's gleaming waterfront district. Closed city roads mean smooth tarmac and iconic skyline views; tropical heat means your pacing and hydration plan matter as much as your fitness.
Respira y flota (breathe and float) — the start is at Helix Bridge, one of Singapore's most photogenic landmarks. Marina Bay is a sheltered urban harbour, so expect calm, flat water with no surf or tidal chop. Water temperature sits around 25–28 °C, which feels like a warm bath — comfortable, but it also means wetsuits are forbidden under race rules. You will need to rely on your natural buoyancy and a relaxed stroke rather than neoprene assistance.
The 80 km bike leg rolls through closed city roads around Marina Bay. The 2027 elevation profile has not yet been officially published, so treat the course as unknown until the final athlete guide drops — check the official T100 Singapore page before you finalise your gear choices. What is confirmed: Singapore's roads are smooth and well-maintained, and the city-centre circuit format typically means multiple loops with crowds cheering you through.
The 18 km run (roughly between a half-marathon and a 10 km — think of it as a long, purposeful run) winds through the Marina Bay waterfront. By the time you reach this leg, the tropical sun will be well up. The 2027 course details are not yet published, but the waterfront setting historically offers some shade from city buildings and crowd energy to carry you home.

Getting there & where to stay

How to fly in
Singapore Changi Airport (SIN) is the gateway — it is consistently rated one of the best airports in the world, so the arrival experience is genuinely pleasant. Most major international hubs have direct or one-stop connections. Book flights early, especially if you are travelling with a bike box, and check your airline's bike-transport policy and fees before you commit. Race-week road restrictions around Marina Bay may affect taxi and rideshare routes, so check the final athlete guide for logistics advice.
Hotels near the start
Where to stay — by what matters to you
Marina Bay — closest to the start line
Staying in Marina Bay puts you within walking distance of Helix Bridge and the transition area. You can walk the course the day before, skip the race-morning transport scramble, and soak up the atmosphere. Hotels here tend to be premium-priced, so book early.
🏨 See stays · affiliateDowntown Singapore — central and well-connected
Downtown Singapore (the CBD and surrounding neighbourhoods) offers a wider range of accommodation prices and excellent MRT (metro) connections to Marina Bay. A good middle ground if Marina Bay hotels are sold out or over budget.
🏨 See stays · affiliateGetting around & the rest of the trip
Aim to arrive at least two full days before race day — ideally Thursday 8 April — to acclimatise to the heat and humidity before you race on Saturday 10 April.
Use Thursday and Friday for registration, a short shakeout swim or run, bike check, and resting in air conditioning. Do not underestimate jet-lag plus heat as a combination.
Transition opens early — confirm exact times in the final athlete guide. Arrive with plenty of buffer; road closures around Marina Bay will be in effect.
Build in at least one full rest day after the race before flying — your body will thank you, and Changi Airport's terminal experience is a lovely way to decompress.

Bringing a support crew?
Marina Bay is one of the world's great urban backdrops, and the closed-road format means spectators get to see athletes against the Singapore skyline. Road restrictions will be in effect, so check the final event guide for confirmed spectator zones and access routes before race day.
- Helix Bridge — watch the swim start and cheer athletes into the water at 7:00 AM
- Transition area — check the athlete guide for spectator access; not all transition zones allow general public entry
- Bike course — closed city roads mean some viewing points will be restricted; look for designated spectator areas in the official event map
- Run course waterfront — the Marina Bay waterfront typically offers open, accessible viewing with great skyline views
- Finish line — the best spot; arrive early to secure a good position and be ready with your loudest cheer
