ABOUT THE ARRS

The Association of Road Racing Statisticians (ARRS) is an independent, non-profit organization that collects, analyses, and publishes results and statistics regarding elite distance running at distances 3000m and longer. Click here for more information.

The data of ARRS is stored in the ARRS database, which has more than 1.3 million performances from more than 240,000 races by more than 95,000 elite and sub-elite distance runners world-wide. It is possible to browse the database through the interface https://more.arrs.run

This website and the ARRS database has been created entirely through volunteer efforts. Many hundreds of people have contributed race results and other useful information over a period of many years. Some of these people have spent a great deal of time vetting the information, correcting errors, adding missing information, and providing ancillary information. If you find what you believe to be an error or if information is missing, please send the information to info@arrs.run

Many of the statistics on this website have been generated from the ARRS database.

The co-founder, coordinator, data manager, website manager, key person and the soul of ARRS - Ken Young (1941 2018) is unfortunately no longer with us.

ARRS is now in a transition process.

THE FUTURE OF THE ARRS

Ken Young's preoccupation with the collection of distance running data and its analysis stretched back many years before the formation of ARRS in 2003. His dedication over the fifteen years from 2003 did much to establish the ARRS organisation and its global network of correspondents.

ARRS has changed markedly since 2003. Less than 10,000 performances were added to the database in 2003. The ARRS network grew significantly and by 2017 more than 80,000 performances were being added to the database each year.

The development of the second ARRS website https://more.arrs.run through volunteers - one of them Juraj Gasparovic became possible. In 2015 this website made the ARRS database accessible online.

In 2016-2017 Ken, Juraj and ARRS were working on a transitional arrangement for data handling and maintenance of this database involving more people, when Ken suddenly passed away in February 2018. It was obvious even before Ken's death that this growing data deluge could not be managed by one person. ARRS was working on a solution so that several people would be able to edit the database and this website in a wiki-style structure.

ARRS is now seeking others willing to work with Juraj Gasparovic in inputting data. If you are interested please contact info@arrs.run

We have two options for the future of ARRS: (a) continue in the regular processing of actual race results, (b) freeze the ARRS scope to the end of 2017 and document only historic results before the end of 2017. Without more volunteers to process results, the entering of future race results will be very difficult. The growth of the sport and sheer volume of results make it impossible for just one single individual to process them.

In order to raise the necessary funds to ensure the continuation of the ARRS and the two ARRS websites, we have made sponsorships available (see below for the list of sponsors). Please contact Andy Milroy - AndyMilroy@blueyonder.co.uk - if you or your organisation are interested in becoming a sponsor.

NOTES

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.

Record Quality
.....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.
