Place is the position among timed finishers in the same race, division and gender; a doubles place is the team's, and a relay place is among all relay teams at that race (relay teams are ranked together). 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.

Burpee broad jump cost 4:34 against the typical Open Men finisher at Yokohama 2025. The burpee broad jump guide shows whether that is strength or pacing, and the workouts that fix it.
