Place is the position among timed finishers in the same race, division and gender; a doubles place is the team's. Runs is the organiser's official run total (it can differ from the eight laps added up by a few seconds), stations the eight stations added up, and roxzone the time moving between them. The age group is the one entered for that race; for a team it is the team’s age group. How the numbers are made.

Left to right is the race in order: run 1, SkiErg, run 2, sled push, and so on. A block wider than the one below it is a slower segment than the typical finisher.

Wall balls cost 8:16 against the typical Open Men finisher at Ghent 2025. The wall balls guide shows whether that is strength or pacing, and the workouts that fix it.
