Race Editor

Generate race JSON

Build a race JSON by choosing an official GT7 track, date, and metadata. Save the output as race.json in a new race folder (for example data/rounds/round-1/races/2026-03-04-example-race/race.json) and add that folder name to your round's round.json. All tracks come from the official GT7 track list. Fields marked * are required.

Save the snippet as race.json in data/rounds/<round-id>/races/<race-id>/, then append the race directory name to the "races" array in data/rounds/<round-id>/round.json.
