JRF HM2026Your race
Wave & target
Your wave sets your gun — it drives the Race morning timeline below as well as every clock, checkpoint and margin on this page. The sliders in Your pace plan reshape it further.
A wave start, and this board is not written from the elite corral: expect up to five minutes between the gun and your own crossing of the start mat. Every cut-off here is a gun-time clock and pays for it.
More fine target
Targets run 1:30:00 to 3:39:25 — the 08:15 cut-off from your gun.
Race morning
Journey timeline
Estimate the whole journey, door to corral, and your target sleep — the timeline below follows both.
- 19:35Lights out — screens off, room dark; the night two nights out matters more than this one
- 19:50Asleep by — 6 h before the alarm, the target, not a promise
- 01:50Alarm — across the room; kit laid out last night, nothing to decide in the dark
- 02:05Breakfast — 40–60 g familiar carbohydrates, low fibre, 2 h 25′ before the gun · 300–500 ml, then stop (Fuel tab)
- 02:05Toilet window, until you leave — the reason breakfast comes this early
- 02:45Last toilet + dress — where you slept is the last certain toilet; start-area ones are backup. Bib pinned the night before
- 03:00Leave for the start — 30 min door to ; parking and the walk are part of it
- 03:30Arrive — Gelora Bung Karno — toilets, kit, : inside 60′ before your gun
- 04:09Start line + open — official rundown
- 04:15Pre-start gel + water — in the
- 04:30YOUR GUN — 1 — every clock on Race Buddy runs from here
Taking the MRT? Get ready before you head to the station. On race morning the very first train only starts running after 03:00 — so plan backwards from that first train, not from your gun: the alarm, the trip to the station and the platform wait all hang off it. The full early-service timetable (⚠️ 2025, carried as printed) is on the Get there tab.
Arriving too close to the gun raises the risk of: stress, a heart rate already high before the start, no time to warm up, a rush to the , forgetting to drink or use the toilet. Arriving too early (say more than 2 hours) isn't ideal either — you can end up standing too long and getting cold or tired.
Your pace plan
Segments
Your plan, segment by segment:
Start like the heat is already ahead of you — it is. The first gun is 04:30; the sun comes up around km 8 at an honest . A conservative first 5 km is not caution, it is the plan.
Splits & chart
Default paces follow a course-shaped plan on a /km base — near-even, with a breath less on the rises — rescaled to your target, so the shape still lands on your time. Elapsed = official km × your .

Your steps (blue slow → red fast) over the measured elevation, redrawn as the sliders move. Δele is the net change per segment. The canvas is flat — 9–28 m — so the shape's work is done by the heat, not the terrain. Elapsed and clock are cumulative at the segment end (your ). Segment boundaries are the four segment ends — km 5, COP1, COP2 and the finish — with the streets between them in the second column; each block's is the Every Kilometer strategy line re-averaged across that block — time-preserving, so the strategy's clock still lands at every boundary. Landmark positions are approximate (±0.2 km) — read off the course GPX, not surveyed; on course, trust the official km markers.

Water stations are the crew's planning positions — the organiser's app map prints no kilometres, so each is set on the half-kilometre near where the map draws it, ±0.8 km. Carry what you need between them.

Adjust your plan
All four sliders share one scale — 6:00 to 8:10 — so the thumbs read as the shape of your effort. Further right is slower.
2.5 % faster before sunrise around km 8, then gradually slower as it warms.
Race with a plan you have rehearsed: load your own watch plan — a PacePro strategy or simple pace alerts — and use it before race day, not for the first time at the start line.
The route
Drawn from the organiser's route GPX (north up), the line colored by your — the same wash as the chart above; numbered dots are segment ends — the landmarks in the table above. ■ start/finish — GBK's east side · ◎ 06:30 · ● — the crew's planning positions, ±0.8 km each · 🕌 the km-2 mushola (the FM's too) · yellow dots = km markers. Read it race week and in the — during the race your watch and the kilometre markers navigate. The chart under the map is the same plan, live-linked — scrub either one and the dots mark the same kilometre; and clock follow your sliders.
The course, measured
The cut-offs will not save you, and now they can catch you. The 2026 clocks sit a breath inside the finish's own : at a 3:30 goal COP2 still holds 10+ minutes, and only the window's ceiling goal meets it with nothing in hand. Heat is still the constraint — start conservatively, run even or slightly negative, and let the drift after sunrise ().
Two passes over the same ground. Semanggi comes twice — COP1 at km 10.5 and COP2 at km 15.5 — and both count from the first gun, not yours.
Air quality is the organiser's other warning this year (safety advisory, 16 Oct). Check a reliable air-quality source in race week and ease off outdoor training when it is poor; with asthma or another breathing condition, see a doctor before you race.
When it gets hard
| km | What happens | The answer, decided now |
|---|---|---|
| 0–4 | Dark, flat, the GBK loop. Subuh fell at 04:09 — the praying at the venue was the morning's first discipline | Settle, do not sprint. The start hands everyone a fresh and a too-fast first kilometre |
| 4–10.5 | North to the Bundaran HI ring (km ≈7.4–7.75), back south to COP1 at Semanggi | This is the easy half — bank nothing, spend nothing. COP2 still holds 10+ minutes at a 3:30 goal; the heat keeps its own ledger |
| 10.5–15.5 | Gatot Subroto south-east, U-turn at ≈km 13.5, back to COP2 — Semanggi's second pass | Sunrise was at ; from here the temperature, not the course, sets your . Drinking on the clock starts now |
| 15.5–19.5 | Sudirman south-west, then the Sisingamangaraja out-and-back — the course's high point (≈28 m) and its only real rise | Short steps up, let the turn around carry you back down. This is where the race finally asks something |
| 19.5–21.1 | Sudirman back to GBK. Nothing left to manage | Whatever is left, spend it |
Nothing new.
Just the next kilometre.
If the plan breaks
| A late and a slow goal | The capped front-load is this case's tool: at most 5 s/km under the goal from the gun, banking ≤1:15 before COP2 — the binding one. Beyond that, bank nothing |
| Hot morning | Ease from the Bundaran HI ring (km ≈7.5), not from the walk. The heat's bill compounds — easing early is the cheap version |
| Behind at a clock | Even 10:19/km from here still answers — read the cut-off card before deciding anything. Steady beats panicking |
| Something hurts sharply | Stop. A costs one race. Sharp pain is a doctor question — not medical advice, a medical tent |
| Dizzy, sick, confused or unsteady — you or a runner near you | Stop, and get the nearest medic. The organiser's heat-stroke warning signs: severe dizziness or headache, nausea or vomiting, feeling extremely hot or weak, confusion, staggering or fainting. Still sweating is not an all-clear — don't wait for dry skin |
