WHAT IS D-RALLY??? D-Rally is a competition for Pony Clubbers, which is similar to a three-day event, only it takes place over the course of just one day instead of three. Competitors are judged in Dressage, Showjumping and Cross-Country jumping. As well, each Pony Club is given a mark for stable management for the day, which is established by judges checking the trailer sites. Ask anyone who went last year...D-Rally is a lot of fun.
