The Half Marathon: A Flat Loop Through Gading Serpong
The 2026 race was held on Sunday 27 September at Summarecon Mall Serpong in Tangerang Selatan. The half marathon started at Gate 1 of the mall and finished at Uptown Park [1][2].
The course stays inside the Gading Serpong township. It heads east past Serpong M-Town and round the Gading Raya golf course, turns south along Jalan Terusan Pondok Hijau Golf with a spur past The Springs Club at 6 to 7 km, and comes back to Jalan Paramount Boulevard at about 10 km. It then runs west past Scientia Square Park and Multimedia Nusantara University, loops south past Cluster Tesla between about 12 and 17 km, and returns along Paramount Boulevard to Uptown Park [3].
It is flat. On the official profile it starts at 28 m, never rises above 38 m and climbs 70 m in total [3]. The organiser calls it a World Athletics certified route designed for personal bests [1], and in 2025 described it as a closed, flat route [4]. Road safety is overseen by the police and the transport authorities [2].
The Obstacle Runs
In 2026 the obstacle runs came in two lengths from the same start: 12 km at 5.35am and 7 km at 6am [5][2]. The 7K map shows three obstacle zones, Warrior Woods at about 4 km, Warrior Labyrinth at 5 km and Warrior Jump at 6 km [6]. The 12K has five obstacles [5], including a Warrior Crawl zone at about 6 km [7]. Both are as flat as the half: the 7K tops out at 32 m with 15 m of climbing, the 12K at 37 m with 30 m [7][6].
In 2025 there was a single 8 km obstacle run with four obstacles and a two-hour limit [8]. Runners from kumparan's running club described it afterwards. One said it was really different from other running events because it was not only on the road, and the obstacles kept it from being boring. Another described the final challenge: a winding maze with artificial rain overhead and climbing plants along it, ending with runners coming out from behind a man-made waterfall into a lake. A third finished with their best time despite the obstacles [9]. The 2026 maps still include a Warrior Labyrinth zone [7][6].
Children aged 4 to 10 had their own obstacle course on the Saturday, at Cluster Mozart in Summarecon Serpong [10][2], with a ramp, a mud crawl, tyres, a balance beam, a bell and a balloon gate [2].
The Weather: 94% Humidity at the Start
Soekarno-Hatta airport, about 13 km north of the start, recorded 25°C at 5am and 5.30am, with a dew point of 24°C, 94% humidity and a 4-knot wind. It warmed to 26°C and 89% humidity at 7am, 28°C at 8am and 30°C with 66% humidity at 8.30am, where it stayed at 9am. The airport reported haze in every observation from 4am to 10.30am [11].
A dew point of 24°C means very wet air, in which sweat barely evaporates, so the flat course is slower than it looks. A two-hour half marathoner finished at about 7.15am, in 26°C to 27°C; runners using the full three and a half hours finished at 8.45am, at about 30°C. The 5K, starting at 6.15am, ran mostly in 25°C to 26°C [11]. The half-marathon map places a cooling station at 14 km [3].
Aid, Cut-offs and Pacers
The half-marathon map shows eight water stations, at about 2.5, 5, 10, 12, 14, 16, 18 and 20 km. The 14 km station also has fruit, energy gel and a cooling station, and there are medic tents, ambulances and medic motorbikes along the course [3]. The rules promise fruit for the half marathon and at the finish, and a rinse station on the half-marathon course [2].
The half marathon had three and a half hours, with checkpoints at 5 km (50 minutes), 10 km (1 hour 40) and 15 km (2 hours 30) [1]. The 12K obstacle run had three hours and the 7K two hours 15 minutes [5]; the 5K had 1 hour 20 minutes [12]. Runners outside the limit get no finisher medal [2]. The start area closes at the official start time, and late arrivals are not allowed to start [2].
Pacers ran at sub-100 minutes, 1:45, 2:00 and 2:15, with a sweeper at 3:15 [1]. Half-marathon finishers got a finisher jersey and medal [1], 12K finishers a finisher jersey and medal [5], and 7K and 5K finishers a medal [5][12].
How the Race Changed From 2025
The 2025 race, on Sunday 5 October, had a half marathon, 10K, 5K, the 8K obstacle run and a kids' obstacle run [9]. Its half marathon started and finished at Uptown Park, at 5.15am with the same three-and-a-half-hour limit, cost Rp800,000 and sold out [13]; the 8K obstacle run cost Rp600,000 and also sold out [8].
For 2026 the 10K was dropped, the obstacle run was split into 7K and 12K, and the start moved to Gate 1 of the mall [1][5][2]. Every 2026 category was marked sold out on the official site [1][5][12][10].
Race Weekend Logistics
Race packs were collected at Unity Lobby, Summarecon Mall Serpong, on Friday 25 September from 10am to 9pm and Saturday 26 September from 10am to 7pm; kids' packs on the Friday only. A representative needed a signed authorisation letter and a copy of the runner's ID [2].
On race morning, race central opened at 3am and runners reached the start through Unity Lobby [2]. Bags went into mobile drop-bag vans near the start and were collected at Uptown Park, between 4am and 9.30am; only the official race bag was accepted, and no phones or other electronics [2]. Taxis and ride-hailing cars pick up from the mall's north lobby, and runners who drive can park across the mall's car parks [2].
Fees are not refunded, but an entry can be transferred to someone else or switched to another race while places remain [14]; bibs cannot be handed over without the organiser's approval [2]. Only Indonesians and foreigners holding a KITAS can win podium places; other foreigners run non-competitively [2]. Half-marathon national winners got Rp20 million and each master age group from 40-44 to 55+ Rp7 million [1]; the 5K paid Rp12 million to its winners [2]; obstacle-run podiums got product packages [5]. BRI's app offered 50% off entry in 2026 [15].
Should You Enter the 2027 Race?
Yes, if you want an obstacle run built on a proper road course, a flat half marathon with a full set of pacers, or a family weekend with a kids' course on the Saturday.
Think twice if you struggle in humid air, since a flat profile does not help much at 94% humidity, or if you are a foreigner without a KITAS hoping for prize money. The half-marathon course also winds through a residential township rather than a city centre.
No 2027 date had been published, and no results or reports of how the 2026 race went had appeared two days after it. The 2026 races all sold out, so watch the official site for the next edition.
