If winning machine Elson Boy can extend his streak to six at Rosehill on Saturday then trainer Dar Lunn sees no reason why connections shouldn’t chase a Kosciuszko dream.

Dar Lunn has Kosciuszko dreams for Elson Boy who will aim to win his sixth race in a row at Rosehill on Saturday.

With the task getting harder at every start, Elson Boy keeps responding to the challenge and the outstanding front-runner made it four successive wins when taking out the 1400m Gooree Cup on Sunday at Mudgee.

For celebrated veteran Dar Lunn, it’ll be sweet satisfaction if Elson Boy with impeccable form lines can win him another Narromine Digger’s Cup at Sunday’s TAB meeting, but it won't compensate for the biggest disappointment of a long career as jockey and trainer.

Last time Dar Lunn had a runner in the Newhaven Park Country Championships Final his horse was a $201 chance, when he heads to Randwick with the dashing front-runner Elson Boy he’ll at least be considered a hope of stealing the $1 million race.
