The slowest that still makes the from your gun: 10:19/km.

Both cut-off clocks and the are the organiser's own 2026 values, published 3 Oct (official page v2). They all count from the first gun, and the HM is a start: every minute of your 's delay is gone from every cut-off on this card. Later waves' gun times are not published yet — the board takes your delay as an input and stays neutral about it. Every clock here is — your is yours alone — and the board holds the start-line spare for you (set it under Race day; up to five minutes is honest for a mid- ). One more: through the second the field is still one . Hold your own plan, and don't get swept along faster or slower than the crowd.

The 3-hourly trend across the race window lands here once the forecast loads — your gun through a slow finish.

Loads once per visit; the last good copy stays on this phone for race morning.

Forecast: BMKG (opens in a new tab), Indonesia's official weather agency — ≈3-hourly readings for the kelurahan around the start line. A forecast is not a promise about race morning; official information always wins.

How to use Race Buddy
  • Race Day tab — set your and target (, finish time, or a 's finish); the default plan is course-shaped on a /km base — reshape it with the sliders
  • Fuel tab — gel and station times for your plan
  • Event tab — the official rundown, course services, links; Prep tab — race-eve checklists
  • After tab — the first hour, the first week and the debrief once you finish

Everything is computed on your device; your inputs stay on your phone (localStorage). The forecast above sends only an area code. Visit counting, if you allow it from the About tab, records the page and a random id for this browser — not your plan.
