LAST Sunday, Te Akau Racing’s Mark Walker became the first trainer in the history of the Grand National Steeple to trifecta the result.

On the all-jumps card at Ballarat, the New Zealander saddled up three of the seven runners in the $400,000 feature over 4,500 metres with his most favoured runner Leaderboard, in receipt of 9kgs from the crowd favourite Stern Idol, whose top-weight of 74kgs proved telling in the end.
