Run your plan from a start time you pick. Nothing is saved.

Your 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.

You cross the start mat ≈05:20:00

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. The finish cut-off counts from the first gun — a gun-time clock — and pays for every one of those minutes.

More fine target

Targets run 0:30:00 to 1:55:00 — the 07:15 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.

  • 20:20Lights out — screens off, room dark; the night two nights out matters more than this one
  • 20:35Asleep by — 6 h before the alarm, the target, not a promise
  • 02:35Alarm — across the room; kit laid out last night, nothing to decide in the dark
  • 02:50Breakfast — 40–60 g familiar carbohydrates, low fibre, 2 h 25′ before the gun · 300–500 ml, then stop (Fuel tab)
  • 02:50Toilet window, until you leave — the reason breakfast comes this early
  • 03:30Last toilet + dress — where you slept is the last certain toilet; start-area ones are backup. Bib pinned the night before
  • 03:45Leave for the start — 30 min door to ; parking and the walk are part of it
  • 04:15Arrive — Gelora Bung Karno — toilets, kit, : inside 60′ before your gun
  • 05:15YOUR GUN — 1 — every clock on Race Buddy runs from here

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.

Start like the clock is already running — it is. The first gun is 05:15 and the finish clock counts from it, thirteen minutes before the {sunrise} sunrise. Your 's delay is real time gone; a controlled opening is not caution — it is the only cheap kilometre you will get.

Splits & chart

Default paces follow a course-shaped plan on a /km base — patient through the corridor, honest on the return — 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 — 9–20 m — so the shape's work is done by the , the crowd and the heat, not the terrain. Elapsed and clock are cumulative at the segment end (your ). Segment boundaries are the seven course landmarks 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.

Adjust your plan

All seven sliders share one scale — 5:35 to 8:25 — so the thumbs read as the shape of your effort. Further right is slower.

Strategy

6 % slower through the dark opening while the corrals feed onto the line, then near-even with a slight fade.

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.

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 · ◎ the U-turn just south of Bundaran HI · ● — the crew's planning positions, ±0.8 km each · yellow dots = km markers. No cut-off rings and no praying place are drawn — the 10K has never had a cut-off point, and the line passes none: the km-2 point sits ≈2.1 km east of the FM/HM mushola. Road names are coordinate reads, not organiser statements. 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

Flat — and honestly so. The GPX reads 9.0–21.1 m above the sea — the chart's 250 m bins smooth the km-8.57 peak to 20 —: out-and-back up the Sudirman corridor to the U-turn's low ground at km 3.58, then a finish loop through GBK over its south-west corner. No organiser gain figure exists for 2026, so this board quotes none.

The cut-off will not catch anyone running — the gate can. The clock gives 12:00/km from the first gun; what ends races is the runners' entrance closing at flag-off ({firstGun}) — late arrivals are . And the clock counts from the first gun: every minute your waits is a minute gone from 07:15. Be at the gate early, start controlled, and let the plan do the rest.

A morning already in motion. The marathon's field started at 04:00 and the venue has been full since — the first kilometre threads through shared gates and past an expo that opens 06:00 (⚠️ 2025 hours). Treat the crowd as terrain: it is the one part of the course no GPX measured.

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

kmWhat happensThe answer, decided now
0–1Dark, out the complex's north-east gate — a start behind a marathon field already running. Subuh fell at 04:09 — the praying before leaving was the morning's first disciplineSettle, do not sprint. The first gun is 05:15; the minutes before your mat are the spare you banked, not a debt to sprint back
1–2North past the Senayan side, finding the corridor's rhythmThe field is still one — hold your line and your plan, not the crowd's
2–4Up the Sudirman corridor to the U-turn just south of Bundaran HI — the low ground, 9.0 m at km 3.58Sunrise lands ≈km 2 for the field: the corridor turns from dark to bright mid-climb. Even effort, not even
4–5.5Back down Sudirman — the same road, now with the sun on itThe return pays back the climb. If the sun makes it feel harder than the out leg, that is the heat starting its ledger
5.5–7Sudirman south, into GBK from the south — halfway goneThe heat-drift kilometre: from here the temperature, not the course, sets your . Drinking on the clock starts now
7–8.6The complex's south-west corner — the course's high point, 21.1 m at km 8.57Short steps up, one real corner. This is where the race asks its one question
8.6–10North-east through the complex to GBK's east side. Nothing left to manageWhatever is left, spend it
The mantra — decided now, so it need not be invented at the U-turn

Nothing new.
Just the next kilometre.

If the plan breaks

A late and a slow goalThe capped front-load is this case's tool: at most 5 s/km under the goal from your own start, banking ≤2:30 before the return leg — the clock is 2 h from the first gun, so your 's delay is already spent. Beyond that, bank nothing
Swept along by the The first kilometre in the dark, behind a marathon field, is the race's most expensive metre. Reset at the north-east gate — the plan still lands if the reset happens at km 1
Hot on the return legEase from the U-turn (km 3.58), not from the walk. The sun lands on the corridor ≈km 2 for the field and the return has no shade worth the name — easing early is the cheap version
Behind the clock's 12:00/km from the first gun still answers — read the cut-off card before deciding anything, and remember the gate, not the clock, is what usually ends this race
Something hurts sharplyStop. 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 youStop, 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
