How to read

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. 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. * 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.
