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. How the numbers are made.

Each station's best across Hendrieka's Doubles Women races, from different races, against the typical Doubles Women split. Venues differ (sled carpets, run laps, where the mats sit), so a best can owe something to the venue.
