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. † This venue did not time the roxzone: the figure is the finish minus runs and stations, and part of the walk is inside the run laps there, so it is shorter than at other venues. The age group is the one entered for that race; for a team it is the team’s age group. * At that edition running was under 44% of the typical finish (48% is normal): the timing mats counted some running as station time, so its runs look faster and its stations slower than they were.
