A 60mm downpour on Friday saw the grassed arena turn to mud.

But competitors ignored the conditions to produce their best performances.

In the show arena, the Marriott family, from Benalla, continued their run of Royal successes by winning the champion clydesdale stallion or colt title with Aarunga Master Ben, which was also named supreme champion Clydesdale.

They also won the best Clydesdale yearling colt or filly with Aarunga Prince.

Showjumping also started last Thursday, with the first week featuring the senior riders and top horses divided into three ranked divisions. It ends with the Sydney Royal Grand Prix final and World Cup qualifier to be held on Wednesday.

Sydney Olympic course designer John Vallance, from Orangeville, was the Royal's course designer, and his technical and careful courses produced very few clear rounds.

Add heavy footing to the mix, and there were some final scores that would have looked better in a cricket match.

Opener: Paul Athanasoff, riding Wirragulla Nicklaus, wins the opening section one class at the Sydney Royal.Section one for the top horses saw Paul Athanasoff, from Dungog, and his stallion, Wirragulla Nicklaus, jump a super double clear round to open the program, which he then went on to win.
