RAS HEIGHT CERTIFICATES
It is a requirement that all Standardbred's competing in classes that are defined by height, carry and present to the steward a current RAS Height Certificate. Individual shows decide which qualifying show schedule they will present to competitors at their show. As it is not generally known until the schedule is released to competitors if classes will be defined by height, it's a good idea to get one at the beginning of the season and carry it just in case.
All the information that you need regarding RAS Measuring can be found on the RAS website.
