The Equestrian Canada Rules for Vaulting in Canada state in Article L301 that: "The criteria for scoring is explained in detail in the FEI Guidelines for Vaulting Judges which is published annually on the FEI Vaulting Website." The notices posted here are supplemental to the FEI Guidelines for cases where the FEI Guidelines do not cover specifics needed in the context of the Canadian rules and/or competition systems.
It is widely known that helmets should not be used when vaulting, but less widely understood why. This page introduces the basics, while our Fall g-Force Calculator page goes into all the details, provides a tool to help assess the level of risk, and states the Risk Management Guidelines for Vaulting.
When you want to enter an event like a CVI or world championships, the requirements are quite different than what you would expect at regular Canadian vaulting competitions. You will be entering on behalf of your country so this involves both Equine Canada and the International Equestrian Federation.
