T100 Triathlon Singapore
Race the glittering heart of a world city — closed roads, warm water, and a finish line framed by the Singapore skyline. The full T100 race takes place on Sunday 11 April 2027; Saturday 10 April is the event weekend opening day (Sprint and relay races — check the official programme).
Where it is
Marina Bay, Singapore
Is this your race?
This is a race for experienced, well-trained triathletes — not because it is impossible to dream about, but because the conditions stack up fast: no wetsuits in warm open water, air temperatures that regularly touch 34 °C, a strict swim cut-off of 1 hour 20 minutes for 2,000 m, and a T100 distance (2/80/18) that demands serious base fitness. Beginner fit 1/5: T100 baseline 2, −1 wetsuits forbidden in warm open water, −1 air temperatures verified above 28 °C, +1 official Sprint/relay option available — clamped to the T100 minimum of 1 after arithmetic yields 1.
✅ You’ll love it if…
- You have already completed at least one Olympic-distance triathlon and are ready to step up
- You have two open-water swim races logged since January 2025 (the organiser requires this)
- You thrive in heat and have trained specifically in warm, humid conditions
- You want a bucket-list city race with one of the most dramatic skyline backdrops in the world
- You are eyeing the Sprint or relay option as your entry point into the T100 world
⏳ Build up first if…
- You have never done an open-water swim race — log two before you register, because the organiser mandates it
- Your longest triathlon to date is Sprint distance — build through Olympic first, then consider this race in a future year
- You have not yet trained in heat and humidity; acclimatisation takes weeks, not days
- You are unsure about swimming 2,000 m without a wetsuit in under 1 hour 20 minutes — that pace needs to be comfortable, not a stretch goal
Not yet? That’s normal. Start here → take the 2-minute Readiness Assessment.
The course, demystified
The T100 Singapore is built for spectacle: a 2,000 m open-water swim in Marina Bay, a closed-road bike loop through Singapore's city streets, and a flat run through the Marina Bay and Gardens by the Bay area — all framed by one of Asia's most iconic skylines. The full T100 race is on Sunday 11 April 2027; Saturday 10 April hosts the Sprint and relay races (check the official programme for the confirmed schedule).
Respira y flota (breathe and float) — the start is in Marina Bay, a sheltered harbour with warm, calm water sitting at roughly 25–28 °C. Because the water is warm, wetsuits are forbidden; you will swim in your tri-suit only. The organiser sets a cut-off of 1 hour 20 minutes for the 2,000 m course, which works out to about 4 minutes per 100 m — a pace you should be able to hold comfortably, not barely. The organiser also requires every swimmer to have completed at least two open-water swim races or events since 1 January 2025 before race day.
The bike leg uses closed city roads — a rare luxury that means no traffic and a smooth surface. The organiser describes it as city racing; the detailed 2027 route and total elevation gain have not yet been confirmed, so treat the profile as unknown until the official athlete guide is published. What is confirmed: you will be riding through the heart of Singapore in race conditions, which means heat management and hydration strategy matter as much as watts.
The run is reported as flat and passes through the Marina Bay and Gardens by the Bay area — some of the most recognisable scenery in Singapore. The detailed 2027 route is still to be confirmed. With air temperatures potentially reaching 34 °C, this is where heat management becomes the race. Slow your early run pace deliberately, use every aid station, and have a cooling strategy ready.

How to fly in
Singapore Changi Airport (SIN) is the gateway — one of the world's best-connected hubs, with direct or one-stop flights from most major cities in Europe, the Americas, and Asia. From the airport, the MRT (metro) runs directly to the city centre in about 30 minutes. Marina Bay is a short taxi or ride-share ride from the central MRT stations. Book flights early; April is a busy travel period for Singapore.
Hotels near the start
Where to stay — by what matters to you
Marina Bay — race HQ on your doorstep
Staying in Marina Bay puts you within walking distance of the Helix Bridge start and the race hub. Hotels here are premium-priced but unbeatable for race-morning logistics — no early taxi stress, easy bike transport, and you can walk the swim exit and transition zones the day before.
🏨 See stays · affiliateCity Centre — practical and slightly easier on the budget
The broader city centre (areas like Bugis, Clarke Quay, or Tanjong Pagar) offers a wider range of hotels at varying price points, all with good MRT or taxi access to Marina Bay. A practical choice if Marina Bay hotels are sold out or outside your budget.
🏨 See stays · affiliateGetting around & the rest of the trip
Arriving at least 48 hours before a 7:00 AM race start gives you time to adjust to the time zone, collect your race pack, and do a short shakeout session. Singapore is GMT+8 — factor in jet lag from western time zones.
Exact expo and check-in dates for 2027 are not yet confirmed — watch the official athlete guide. The T100 full race is on Sunday 11 April; check-in is likely on Friday 10 April or Saturday 11 April. Keep both days as clear as possible of other plans.
A 7:00 AM start means a very early wake-up — budget at least 90 minutes before gun time for breakfast, kit prep, and transition setup. Stay as close to the start as possible. Note: Saturday 10 April is the event weekend opening day (Sprint and relay races).
Give yourself at least one recovery day before a long-haul flight if possible. Your legs will thank you, and Singapore is worth an extra day of exploring.

Bringing a support crew?
Marina Bay is one of the world's great spectator venues — iconic landmarks, waterfront promenades, and a city that knows how to put on a show. Road closures will affect some access points, so check the final athlete guide for spectator maps and restricted zones.
- Helix Bridge area — watch the swim start and exit; one of the most dramatic backdrops in triathlon
- Marina Bay waterfront promenade — good sightlines for multiple points on the bike and run course
- Gardens by the Bay vicinity — likely visible on the run leg; check confirmed 2027 route before planning
- Finish line — the place to be; arrive early for a good spot as the course is on closed city roads
- Check the official spectator guide before race day — road closures may require specific access routes and timing
