What Is the HGMA Run?
The HGMA Run is a road race organised by IHGMA — the Indonesian Healthy Gymnastics Medical Association (Ikatan Healthy Gymnastics Medical Association) — scheduled for October 11, 2026, at Stadion Brawijaya in Surabaya, East Java [1]. The event offers three distances: a 21.1K half marathon, a 10K, and a 5K — a format that accommodates serious road racers, recreational runners, and families alike [1].
IHGMA is a medical-professional organisation that promotes health through physical activity, and its involvement as the race organiser gives the HGMA Run a distinctive character: this is a race where the health-promotion mission is baked into the event's DNA, not added as an afterthought through a charity partner [2]. The association's website (ihgma.org) and its presence on Indonesian running calendars suggest an organisation that is serious about building a recurring event rather than a one-off fun run [2].
Registration is listed as being handled through the Amasol platform (rm.amasol.co.id), a registration provider that has powered numerous Indonesian road races [3].
Stadion Brawijaya: Surabaya's Central-City Race Hub
Stadion Brawijaya is a multi-purpose sports complex located in central Surabaya, roughly halfway between the city's commercial core and its southern suburbs [4]. The stadium and its surrounding grounds provide a natural race village: start and finish lines can be set up on the stadium track or in the adjacent parking areas, with the stadium's permanent facilities — toilets, changing rooms, sheltered seating — providing infrastructure that most Indonesian road races (which often start on closed public roads with portable toilets as the only amenities) cannot match [4].
The stadium's central location is well-served by Surabaya's transport network. It is accessible via Jalan Brawijaya and the surrounding road grid, and is within a 15–20 minute drive from most parts of the city [4]. For runners using ride-hailing (Gojek or Grab, both ubiquitous in Surabaya), the stadium is a well-known landmark that drivers will find without difficulty [4].
The area around the stadium is predominantly residential and institutional, with wide roads that can support a road race course with partial or full road closures [4]. The terrain in central Surabaya is flat — Surabaya sits on the coastal plain of eastern Java with no significant elevation changes — meaning the half-marathon course is likely to be fast and accessible, with the only challenge coming from the climate rather than the topography [4].
October 11: End of the Dry Season in East Java
October 11 falls at the very end of East Java's dry season — the transition period before the onset of the northwest monsoon, which typically arrives in November [5]. The weather is characterised by warm mornings (24–27°C), moderate to high humidity (75–85%), and an increasing but still manageable risk of afternoon rain [5].
For a half marathon starting at 5:00–5:30am, runners can expect to finish before 8:00am, when temperatures are still in the mid-to-high 20s. This is warmer than ideal racing conditions but significantly more comfortable than the March–May period, when Surabaya temperatures can exceed 30°C by 8:00am [5]. The humidity will be the primary performance variable — runners should expect to sweat heavily from the opening kilometres and should hydrate at every available aid station [5].
The flat Surabaya terrain partially compensates for the warm conditions. With no hills to break rhythm or spike heart rate, runners can settle into a steady pace and focus on managing their effort through the heat rather than fighting the course itself [4]. For Surabaya-based runners accustomed to training in these conditions year-round, October 11 represents a fair — if not fast — racing day [5].
Registration, the Amasol Platform, and What to Expect
Registration for the HGMA Run 2026 is listed as being handled through the Amasol platform at rm.amasol.co.id [3]. Amasol is a well-established Indonesian event registration provider that handles everything from small community runs to larger regional races — it supports online payment through Indonesian bank transfers and e-wallets, digital bib assignment, and e-certificate delivery [3].
Based on the Indonesian race calendar pattern, expect registration to open approximately two to three months before race day (around August–September 2026) [1]. Indonesian half marathon entry fees typically range from IDR 150,000–350,000 for early-bird registration — expect HGMA Run to fall within or slightly below this range, consistent with its community-health orientation [1].
Race-kit inclusions for Indonesian races of this scale typically feature an event shirt (cotton or dry-fit, depending on the organiser's budget), a race bib (likely manual timing rather than chip-based for a community race), and a finisher's medal [1]. The stadium venue means bag-drop facilities are likely to be available in the stadium's permanent infrastructure — a significant convenience over the temporary tent-based bag drops common at roadside-start races [4].
Should You Run the HGMA Run 2026?
If you live in Surabaya or the surrounding East Java region (Sidoarjo, Gresik, Mojokerto, Malang): yes, this race should be on your radar for October 2026. The central stadium venue, the three-distance format, and the flat Surabaya terrain combine to make this a convenient and accessible addition to the East Java running calendar [1][4].
If you are a medical or healthcare professional: the IHGMA connection may add a layer of interest — this is a race organised by your professional community, and the health-promotion framing may come with additional programming (health screenings, medical talks, or wellness exhibitions) that commercial races do not offer [2].
If you are a runner from outside East Java or an international participant: hold off on booking travel until the course map and registration details are published. Surabaya has good air connectivity via Juanda International Airport (SUB) and a range of accommodation from budget to five-star, so the logistics are workable — but the race itself needs to justify the trip, and right now there is not enough published detail to make that case [1][4].
