The Association of Road Racing Statisticians is an independent, non-profit organization that collects, analyzes, and publishes statistics regarding road running races. The primary purpose of the ARRS is to maintain a valid list of world road records for standard race distances and to establish valid criteria for road record-keeping.[1] The official publication of the ARRS is the Analytical Distance Runner.[2] This newsletter contains recent race results and analysis and is distributed to subscribers via e-mail. The ARRS is the only organized group that maintains records on indoor marathons.[3]
