What do these buttons do?
  • Participants — manage your start list (number, name, sex, birth year) or import a CSV (number,name,sex,birth_year). Names and sex/age categories then show up in the results.
  • Export CSV — download all results as a spreadsheet (place, name, time, pace…).
  • Export PDF — a clean, print-ready results sheet (your browser's “Save as PDF”).
  • Backup — save the whole event (start time, results, participants) to a .json file.
  • Restore — load an event back from a backup file (replaces current data).
  • Clear results — delete all recorded finishers. Your start time and participant list stay.
