These are the gold bar. Courses measured
using USATF guidelines are measured to an
exacting standard used by the world's most
demanding races. From the NYC Marathon to your local 5K, having a course USATF certified ensures the proper distance, just keep in mind...USATF Certified Courses use the "shortest route possible" and are measured first with a calibration course (defined distance measured by steel tape) and then ridden a minimum of twice using a USATF approved and
calibrated counting wheel. If you're interested in more info on the USATF Course Certification procedures, click here!
