Race Committee Help
This guide explains what each visible element does on the RC screen. This app works best on a tablet or laptop sized screen, but can work on a phone if you are desperate or have a simple race. On a tablet the layout changes whether it is in portrait or landscape (laptop gets the landscape version):
Top Header: Badges and Countdown
- Raised Flags — shows flags currently active by race state/timeline (for example RC, AP, class/prep flags, abandonment flags etc.)
- Series/Race Name — Set from imported series presets, or click to edit.
- Clock 🕒 — current server-synced time used by race countdown logic.
- Course 🗺️ — current course marks string (for example
1-5-1-5-0). - Start Badge(s) — status badge for each start (waiting/running/postponed/general-recall context) with 5-minute countdown and elaspsed time when appropriate.
