JRF 5K2026Your 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 mass start shared with families and first-timers: expect a couple of minutes between the gun and your own crossing of the start mat. The finish cut-off is a gun-time clock and pays for it.
More fine target
Targets run 0:15:00 to 0:58:00 — the 06:15 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.
Your pace plan
Segments
Your plan, segment by segment:
Start like the crowd is the obstacle — it is. The gun is 05:15, thirteen minutes before the {sunrise} sunrise; the first 2.5 km run in the dark, in a . A controlled first half is not caution — it is where the fast half comes from.
Splits & chart
Default paces follow a course-shaped plan on a /km base — banked early, cashed late — rescaled to your target, so the shape still lands on your time. Elapsed = official km × your .
| # | Segment — landmarks | distance | km | Δele | elapsed | clock | pace |
|---|---|---|---|---|---|---|---|
| 1 | GBK east side → the loop's north-east corner | 1 | 0–1 | +2 m ↑6 ↓4 | 0:07:10 | 05:24:10 | 7:10.2 |

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 — 15–22 m, the GPX's own 14.4–21.8 smoothed into 250 m bins — so the shape's work is done by the crowd and the plan, not the terrain. Elapsed and clock are cumulative at the segment end. Segment boundaries are the five 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.

|---|---|---|---|---|
| 1 | GBK east side → the loop's north-east corner | 0–1 | 05:24:10 | 7:10.2 |
| 2 | north-east corner → south-west through the middle → halfway | 1–2.5 | 05:34:48 | 7:05.2 |

This board draws no station table: the organiser's app map shows one on the Sudirman stretch, serving the outbound and the return, and prints no kilometre for it — the crew has not fixed one. Carry what you need.

Every full kilometre, then the finish. Notes break the kilometre into the blocks it crosses — distance → for each piece — so a kilometre that straddles a segment boundary shows both paces.

Adjust your plan
All five sliders share one scale — 5:35 to 8:25 — so the thumbs read as the shape of your effort. Further right is slower.
A third of the race at a time, each block 2.5 % faster than the last — banked for the fast half after halfway.
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 · yellow dots = km markers. No cut-off rings and no praying place are drawn — the 5K has never had a cut-off point, and the line never reaches the FM/HM km-2 mushola. One sits on the organiser's app map — passed both ways; it prints no kilometre, so none is drawn. 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-off will not catch anyone running — the gate can. The clock gives 12:00/km from the gun; what ends races is the runners' entrance closing at flag-off ({firstGun}) — late arrivals are . Be at the gate early, start controlled, and let the plan do the rest.
One loop, two halves. Everything to halfway (2.5) is the crowded, dark half; everything after is the fast half — the height is spent by the south-west corner and the last 2.5 km runs gently home.
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 |
|---|---|---|
| 0–1 | Dark and crowded: one mass start, families and first-timers ahead. Subuh fell at 04:09 — the praying before leaving was the morning's first discipline | Settle, do not sprint. The crowd's first kilometre is always too fast, and yours has 4 more to give |
| 1–2.5 | South-west through the middle of the complex, past the low point at km 1.30, to halfway | Hold the bank — everything after 2.5 is the fast half, and it only pays if you arrive there unspent |
| 2.5–3.5 | On to the loop's south-west corner — the high point, km 3.25, the course's only real rise | Short steps up; sunrise was at and the field is stretching out. This is where the race asks its one question |
| 3.5–4.5 | Back north-east, giving the height straight back | Let the slope pay you. Whatever you banked at halfway, this is where it starts earning |
| 4.5–5 | The long straight home to GBK's east side. Nothing left to manage | Whatever is left, spend it |
Nothing new.
Just the next kilometre.
If the plan breaks
| Swept along by the crowd | The first kilometre in a mass start is the race's most expensive metre. Reset at the north-east corner — the plan still lands if the reset happens at km 1 |
| Feeling too comfortable | A 06:15 clock is 12:00/km from the gun — comfort is not a reason to spend early. The plan banks for the fast half; let it |
| Behind the clock's | 12:00/km from the 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 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 |
