About Calibration Courses
What is a Calibration Course?
A calibration course is a precisely measured line 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 reference distance that allows measurers to control for variations in temperature, tire pressure, and riding surfaces that impact bicycle measurements.
Using This Map
This interactive map displays USATF calibration courses in the United States and Athletics Canada calibration courses in Canada. Measurers, race directors, and running clubs can use the map 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.
Resources for Measurers: If you're interested in becoming a course measurer or need more information about the certification process, visit the USATF Road Running Technical Council website (US) or the Athletics Canada certified courses website (Canada).
