After a request for an episode covering prohibited substances and how to make sure you're on the right side of the rules, we sit down with Claire Williams the Executive Director of the British Equestrian Trade Association about their NOPS scheme, what that involves and what we need to be careful of to make sure we don't fall foul of their prohibited substances list. This one is super important if you compete affiliated with any organisation, not just British Eventing, British Showjumping, British Dressage or the FEI, as more and more Pony Clubs and Riding Clubs are testing for this stuff. Let us know what you think!
