Key Race Metrics & Overview
- Date
- Sunday, 11 April 2027
- Venue
- F1 Pit Building, 1 Republic Blvd, Singapore 038975
- Distance
- T100 — 100km total
- Start Time
- TBC — exact 2027 wave times aren't published yet. The 2026 100km race required the last swim lap to start by 9:00am, with the race closing at 4:15pm.
- Draft-Legal Bike
- No — non-drafting
- Cut-Off
- No official 2027 cut-offs are published yet. As a guide, the 2026 100km cut-offs were: last swim lap started by 9:00am (or 40 minutes after your individual start) with the last swimmer out by 9:40am; last bike lap started by 12:15pm with the last cyclist in by 1:00pm; race closed at 4:15pm. Athletes who miss a discipline cut-off can still move on to the next one and finish, classified as 'Non-Scoring' with a zero split recorded for the missed section, rather than being pulled from the race.
Also this weekend
The 2027 weekend runs Saturday 10 April (Sprint Triathlon) and Sunday 11 April (the full T100, plus Duathlon Long and Duathlon Standard). Notably, the 2027 registration page does not currently list an Olympic-distance triathlon or a Youth Aquathlon — both of which ran in 2026 — so treat those as not currently on sale rather than confirmed gone.
Sprint
Races on the Saturday. 2026 had this at 4 bike laps and 2 run laps.
Duathlon Long
A run-bike-run format (roughly 9.5km/64km/9.5km per the 2027 listing) — no swim leg.
Duathlon Standard
The shorter run-bike-run option (roughly 4.5km/32km/4.5km per the 2027 listing).
Leg 1 of 3
Swim — 2km
Two laps of a small rectangular course in Marina Reservoir — freshwater since the Marina Barrage dam sealed the bay off from the sea in 2008 — with an "Aussie exit" between laps onto a pontoon before re-entering.
- Venue
- Marina Bay / Marina Reservoir, near the Helix Bridge and ArtScience Museum
- Elevation gain
- No official figure published — see notes above
- Surface
- Reservoir — freshwater, sheltered.
Wetsuit: Forbidden, per the official event FAQ — Singapore's near-equatorial water is simply too warm for one. Expected race-weekend water temperature is around 25-29°C.
Leg 2 of 3
Bike — 80km
Five laps out from the F1 Pit Building along Nicoll Highway and the East Coast Parkway to a turnaround, back via Republic Avenue and Beach Road. Flat by nature — Singapore has no real hills — though the guide describes it as undulating, likely referring to bridge and overpass gradients.
- Venue
- Nicoll Highway and the East Coast Parkway
- Elevation gain
- No official figure published — see notes above
- Surface
- Closed/marshalled road — flat.
Non-drafting
Leg 3 of 3
Run — 18km
Two laps around the south side of Marina Bay, passing the F1 Pit Building, Helix Bridge, Singapore Flyer, Marina Bay Sands and Gardens by the Bay. Flat throughout.
- Venue
- The Marina Bay waterfront
- Elevation gain
- No official figure published — see notes above
- Surface
- Closed road and waterfront path — flat.
Transitions
A single transition at the F1 Pit Building serves both T1 (swim-to-bike) and T2 (bike-to-run) — the whole event now finishes on the F1 Track itself, consolidating everything into one venue.

Where T100 Singapore starts and finishes
T100 Singapore starts at F1 Pit Building, 1 Republic Blvd, Singapore 038975 and finishes at Marina Bay / Marina Reservoir, near the Helix Bridge and ArtScience Museum. We haven't been able to place those on a map accurately enough to show one — a pin in the wrong place is worse than no pin.
These are the start and finish points, not the route. Verus doesn't hold course files for this race, and drawing a line between two pins would be a guess you might end up training on.

Race Day Info & Checklist
On the day
- Wetsuits are forbidden for the swim — Singapore's water is too warm for one, typically 25-29°C on race weekend.
- Race pack (2026, 100km): a security wristband, swim cap, race-number tattoos, a sticker sheet, a race bib, a timing chip, and three transition bags (T1 swim-to-bike black, T2 bike-to-run red, after-race white). Sprint and Youth entrants get a single after-race bag only, with gear left at the bike rather than bagged.
- Timing chip worn on the left ankle — a lost or unreturned chip cost US$75 in 2026.
- Bike aid stations (one per lap) serve isotonic drink, gels and water; run aid stations (four per lap, roughly 1km apart) add food, cola, sponges and ice. Discarding litter outside the marked zones is a 30-second penalty.
- Non-drafting bike leg: a 12m draft zone with 25 seconds to complete a pass. 2026 penalties: 100km 2 minutes for each of a first and second offence before disqualification on a third; Olympic 1 minute for each of a first and second before disqualification on a third.
- No parking at the F1 Pit Building or Singapore Flyer — nearest options are Millenia Walk or Marina Square. Nearest MRT is Promenade (Circle/Downtown lines); bikes are not permitted on the MRT, and the Helix Bridge approach is closed to bicycles all race weekend, so most athletes are encouraged to cycle in directly or use a drop-and-go zone.
- The 100km distance doubles as a qualifier for the Qatar T100 Age-Group World Championships — top 10 per age group and gender in the 2026 edition, qualifying for the December 2026 championships. The equivalent pathway for the 2027 race hadn't been published at the time of research.
- FinisherPix provides complimentary race photos as part of entry, shooting at the swim exit, bike course, run course and finish line.
Checklist
- No wetsuit — it is forbidden here, so pack a tri-suit or swimskin instead
- Bike, helmet (mandatory) and bike shoes, checked in the day before racing (no race-morning bike check-in for 100km/Olympic/Duathlon)
- Run shoes and light, breathable kit — expect 26-34°C air temperature and high humidity
- A transition bag or mat to keep T1/T2 kit organized
- Sun protection and a genuine heat-acclimatisation plan if you are not used to equatorial conditions
- A meeting point agreed with family/friends at the F1 Pit Building Festival Village for afterwards
Transport, Spectating & Where to Stay
Transport
Promenade MRT station (Circle Line and Downtown Line) is the closest stop to the F1 Pit Building — bikes are not allowed on the MRT, so plan your bike transport separately if you need one.
No parking at the venue itself; the nearest car parks are Millenia Walk and Marina Square. A drop-and-go zone operates at the F1 Pit Building on the Friday and Saturday, and a pick-up zone on the Sunday.
Extensive closures around Marina Bay for the race weekend — Sheares Avenue/ECP, Rochor Road, Beach Road, Nicoll Highway and Republic Avenue/Boulevard all close in stages, roughly Saturday 11:00-18:00 and Sunday 03:00-16:00 in 2026.
Spectator guide
The F1 Pit Building covers the swim exit, transition and the finish; the waterfront path past Marina Bay Sands and the Helix Bridge gives repeated views of the lapped run.
Marina Bay is compact and walkable for spectators, though the same road closures that affect athletes also affect anyone trying to drive across the area on race day.
Where to stay
Marina Bay / Downtown Core
+ Walking distance to the F1 Pit Building, transition and the finish — everything about the weekend is on the doorstep.
– Singapore's most expensive hotel district.
Bugis / City Hall
+ A short MRT ride from the venue, with a wider range of hotel prices.
– Not walkable on race morning given the road closures.
Frequently Asked Questions

What distances does T100 Singapore offer?
The full 100km T100 distance (2km swim/80km bike/18km run), a Sprint Triathlon, and two Duathlon (run-bike-run, no swim) distances. The 2027 registration page does not currently list an Olympic triathlon or Youth Aquathlon, though both ran in 2026.
Do you need a wetsuit at T100 Singapore?
No — wetsuits are forbidden here. Marina Bay's water is typically 25-29°C, far above any wetsuit-legal threshold.
