Harold started riding at the age of 8, but his beginnings in club events were very complicated. He quickly moved on to eventing, which he practiced for about ten years. Not having any horses to compete in the Junior and Young Rider circuits, he still had the opportunity to train 3 to 4 year olds who became real stars of the Grand Prix 3, 4 and 5* which allowed him to fully launch his professional career.

His best results up to now.

Victory in the Lisbonne CSIO 3* GP with Quolita Z
