About USATF Calibration Courses
What is a Calibration Course?
A calibration course is a precisely measured distance used by course measurers to calibrate their bicycle's Jones Counter before measuring a road race course. This calibration process ensures accurate race distances for certified courses across the United States and the world.
Why Are They Important?
Calibration courses are fundamental to the road race measurement process. They provide a standardized reference distance that allows measurers to control for variations in temperature, tire pressure,and riding surfaces that impact bicycle measurements.

This interactive map displays all USATF calibration courses. Measurers, race directors, and running clubs can use this resource to locate nearby calibration courses for race measurement.
Course Status
Calibration courses, like race courses, have expiration dates. This map indicates both active and expired courses, with details on each course's certification date, expiration, and exact location when available.
