Intermediate riders may now compete in Young Horse and Green Horse competitions.
Previously the competitions were restricted to riders graded Advanced Intermediate and higher.
In show jumping and eventing, the competitions are traditionally run over a 0.90m track while the young horse class is run over a 0.80m track at the National Hunter Trials Championships.

Young Horse competitions are open to horses aged 4 & 5 years while Green Horse competitions are open to horses needing experience and applies for one calendar year commencing 1st January.
