How to read

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 organiser timed all eight stations and the total is theirs, but one split is not used in comparisons: it was under our floor for that station (just under the fastest Elite 15 splits ever), which usually means a timing slip at the mats or a short course. Open the splits to see it. The age group is the one entered for that race; for a team it is the team’s age group.
