• Bib pinned — four pins, front, flat (the night before, not race morning); the timing chip is usually pre-attached to the bib — still check it once, and make sure it is not folded
• Shoes you have already run long in — no new shoes on race day, laces tied the night before
• The socks and kit you have trained in — nothing unsweated
• Cap or visor — sunrise ≈, the last hour runs into low sun
• Anti-chafe applied, not packed — underarm, inner thigh, bra line, nipples. 10 km of tropical sweat finds every seam
• Sunscreen on before you leave — the last hour runs east into open low sun
• Sunglasses — the cap handles heat, not glare down a long straight road
• Hair tied, if that is you
• One key only — in a zip pocket, never loose in a shorts pocket

• The gels your fueling plan counts — in a pocket you have rehearsed
• Phone, charged — the dead-watch backup (kit table below), and the way home
• Phone in a ziplock — sweat kills more phones than rain does
• A packet of tissues — the portable toilets run out of paper before the last wave
• Wet wipes — the portable toilets here run on water, not paper; one pack keeps you clean before the gun
• Small cash or e-money — the backup when the phone dies and QRIS stops; the ride home, a drink. The ATM queue at 03:00 is not a plan
• ID on you — KTP, or a photo or photocopy of it. If something blocks your start, the organisers match entries against personal data
• Your own meds — inhaler, allergy tablet. Anything you would want at km 15, where there is no pharmacy
• Emergency details on the back of your bib, if they are not pre-printed — name, a contact number, blood type, any allergy. Big races print them so bibs cannot be swapped; check first, write later

• Breakfast physically in the room tonight — nobody buys bread at 02:35. The what and how much is on the Fuel tab
• A small bottle for the corral as a backup — the organisers usually set out water at the start line; if you sip before the gun, bin it before the start
• A bottle on course, or not — follow your running strategy — three stations, one every 2.5 km. Sweat heavily? Your own bottle or soft flask is the wiser carry; otherwise the stations are enough
• An electrolyte tab or salt cap if you sweat heavily — the on-course drink is a sports drink, but the morning is humid

The Event tab still asks: bag drop — is there one, where, until when? If the answer is no, this group becomes a supporter, or the car.

• A dry shirt
• Sandals or slides — feet swell, laces hurt
• A plastic bag for the wet kit
• Power bank and cable
• Something to eat, if the finisher pack turns out thin

• Watch charged, plan loaded — load your own watch plan (a PacePro strategy or pace alerts) and rehearse it before race day
• Two alarms, one of them not on the phone you sleep beside
• Everything laid out flat on the floor, and a photo of it on your phone — the photo is the re-check at 02:35, when you are half awake
• Open Race Buddy once with the data off — it is an installed app; confirm it loads before you need it in a corral with five thousand phones on one cell tower. Then export the plan as an image and download it — a picture in your gallery opens without the app and without signal
• Check the race-morning forecast on the Today tab — BMKG publishes about three days ahead; decide your rain kit tonight, not at 02:35

• Earphones — only if the event's rules allow them; a mass start needs your ears too
• A standard watch for backup — plain time on your wrist if the GPS watch fails
• Blister plasters
• A smear of Vaseline on the eyebrows — heavy sweaters: salty sweat stings when it drips into the eyes; a greased brow sends it sideways
