|The ARRS focuses on elite distance running at distances 3000m and longer. Many of the statistics on this website have been generated from the ARRS database which has more than 900,000 performances from more than 160,000 races by more than 35,000 elite distance runners world-wide. This database and website would not be possible without the contributions of hundreds of people and many thousands of volunteer hours by dedicated ARRS members.

Road performances are classified as "record quality", "statistically valid", or "statistically invalid" based on the start/finish separation and the net drop of the course.
.....Start/finish separation is less than 30% of the race distance and the net drop is less than 1.0 m/km
Statistically Valid (suffix "a")
.....The net drop is less than 5.0 m/km and the net effect of tailwind and/or drop does not exceed 5 sec/km
Statistically Invalid (suffix "x")
.....The net drop is 5.0 m/km or more
.....The course has been shown to have been short on remeasurement
.....The course is suspect based on an analysis of the race time bias that exceeds 5 sec/km faster than expected (-5.0 sec/km)
Only record quality performances are included in national and world road record lists. Record quality and statistically valid performances are included in rankings lists.
Multi-part names such as "van der Weijde" may appear in computer generated lists and elsewhere with the spaces removed, i.e., "vanderWeijde." This has been done for the purposes of efficiency in entering performances into the database.
