The Course: Marina Bay to East Coast Park and Back
The half marathon starts and finishes at Marina Barrage [1]. The organiser's 2025 GPX file runs from the Barrage through Marina South, up past Marina Bay and Kallang to the National Stadium area, across into Gardens by the Bay East, and then east along the coast to its far point at about 15 km in East Coast Park before turning back to the Barrage [2].
The route map now posted, labelled for 2026, appears to follow the same line [2][3]. It names the roads: Marina Gardens Drive and Sheares Avenue first, then Bayfront Avenue, Raffles Avenue, Republic Avenue and Merdeka Bridge to the stadium, Tanjong Rhu, a bridge into Gardens by the Bay East, and the out-and-back through East Coast Park [3]. The 10 km runs the same city loop but skips East Coast Park, finishing along Gardens by the Bay East beside Marina Bay [3].
The Weather: Warm and Saturated From the Start
Changi Airport, about 16 km east of Marina Barrage, recorded 27°C at 5.30am on race morning, with a dew point of 25°C, 89% humidity and a 2-knot wind [4]. It barely moved for two hours: 26°C to 27°C and 89% to 94% humidity until 7am. By 7.30am it was 28°C with a 26°C dew point, and by the 9.30am half-marathon cut-off 30°C with 79% humidity. Light showers arrived at 10am [4].
A dew point of 25°C to 26°C means sweat barely evaporates, so the body struggles to cool itself even before sunrise. A two-hour half marathoner finished at about 7.30am in 28°C air; a runner using the full four hours finished at 30°C. Start slower than your usual pace and drink at every station.
Aid Stations and Cut-offs
The half marathon started at 5.30am with a four-hour limit, and the 10 km at 6.30am with two and a half hours [1]. Finishers inside the limit got a medal and an e-certificate, and half marathoners also got an ASICS finisher tee [5]. Pacers ran at 1:45, 2:00, 2:05, 2:15 and 2:30 for the half, and 50, 60 and 70 minutes for the 10 km [6].
Before the 2025 race the organiser promised no more than 2.5 km between hydration points [7]. The map posted for 2026 lists eight stations on the half, at 2.5, 6, 7.8, 11.6, 14.3, 16.2, 17.2 and 20 km. All serve water, three also serve isotonic drink (6, 11.6 and 17.2 km), and the only food is bananas at 17.2 km [3]. That leaves two gaps longer than the promise: 3.5 km between the first two stations and 3.8 km between 7.8 km and 11.6 km, which is where the course leaves the city for East Coast Park [3].
For 2026 the rules measure the cut-off from the last starter crossing the start line, and add intermediate cut-off points along the route; runners who miss them are pulled off the course [8].
What Changed After the 2024 Debut
The first Singapore edition in 2024 was criticised for long queues at bag drop and race-pack collection [9]. In an interview before the 2025 race, SportPlus put the other complaints to the organiser: a start line on a slope, no staggered start by pens, poor signage, doubts about the route distance, hydration, and long waits for finisher tees [7].
The organiser, a new team for 2025, promised start pens, a dedicated bag-deposit team, a re-measured route tested by athletes and runners, and more large shirt sizes [7]. SportPlus reported on race day that check-in, gear drop-off, hydration points and volunteers had all improved, and called it one of Singapore's best-run endurance events of 2025 [9]. The race village had recovery zones, hydration booths and live entertainment [9].
How Fast the Field Is
The 2025 race had a competitive pen for runners chasing prizes [7], and only runners who start in it can win [10]. In 2025 the half marathon was won by Joseph Mwangi Ngare in 1:13:11, three seconds ahead of Subas Gurung, and by Rachel See in 1:24:34 for women. Fifth place was 1:18:27 for men and 1:30:26 for women [9]. The 10 km went to Shaun Goh in 31:48 and to Vanessa Lee in 41:01, one second ahead of Nicole Low; fifth was 37:53 and 44:28 [9]. The top five in each race won cash [11].
For 2026 the competitive pen needs a qualifying time under 1:30 for men and 1:50 for women in the half, or under 40 and 50 minutes in the 10 km [12]. Prize money runs from S$1,000 for first in the half to S$200 for fifth, and from S$500 to S$100 in the 10 km [12]. A half marathoner who can run in the low 1:20s (women) or high 1:10s (men) was in the prizes in 2025.
Race Weekend Logistics
Race packs were collected at Geneo in Singapore Science Park from 3 to 5 October 2025, 11am to 8pm, about 9 km west of the start [13][14]. Overseas runners could collect on race morning from 3.30am to 6.30am at the Marina Barrage race village, and the organiser asked them to come at least 45 minutes before their start because of queues [13]. For 2026, collection is again at GENEO, from 16 to 18 October, 10am to 8pm [14].
In 2025 the half marathon cost S$78 to S$98 and the 10 km S$58 to S$78 depending on when you entered, before 9% GST and an 8% processing fee [11]. For 2026 the prices, including GST, are S$105 and S$125 for the half and S$85 and S$105 for the 10 km, plus the 8% processing fee [12]. Entries cannot be transferred or refunded, and you cannot switch distance [8]. The 2026 organiser asks runners to arrive 45 minutes before the start, or an hour before if depositing a bag, and strollers are not allowed [8].
Should You Enter the 2026 Race?
Yes, if you want a half marathon or 10 km of manageable size on Singapore's waterfront, a four-hour half-marathon limit that suits walkers and first-timers, or a realistic chance of prize money if you run in the competitive pen.
Think twice if you race badly in humidity or rely on frequent aid, since the air at the start was already saturated and two stretches of the half go more than 3.5 km between stations on the posted map [3][4].
The 2026 race is on Sunday 25 October at Marina Barrage [12]. The organiser says flag-off times will be announced once the authorities approve them [12], so check the start times and the final route before you plan how to get there before dawn.
