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. A dash in runs, stations and roxzone on a result from the live results service means the splits are not in yet (finish time only). The age group is the one entered for that race; for a team it is the team’s age group. A dash means the organiser did not publish that number for the result. How the numbers are made.
Houston 2025, against 226 Pro Men
Shape of the race
Each spoke is one segment (roxzone is the time moving between stations). The further out, the bigger the share of the field beaten on it. A round shape is an even race; a dent is a weak station.
How you ranked on each segment
Longer is better: the share of the field this segment beat.
Minutes against the typical finisher
Green, left of centre: faster than the typical Pro Men finisher at this race. Orange, right: slower, and by how much.
The race as one bar: Jack against the typical Pro Men finisher
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.
