Henry de Bromhead heads down a tried-and-tested route as he starts off Sizing Rio's chasing career at Punchestown on Saturday.

The County Waterford trainer has used the Punchestown For Events Beginners Chase over two and a half miles as the springboard for the fencing debuts of such stars as Sizing Europe in 2009 and Loosen My Load in 2010, with both winning.

Sizing Rio has been highly-tried over the smaller obstacles, landing a Grade Three and then competing at big meetings in Leopardstown, Fairyhouse and Punchestown.

"He jumps well - he won a point-to-point - so hopefully we'll start him off over fences and see how we go," said De Bromhead.

"Sizing Europe and Loosen My Load both started their chasing careers in this particular race.

"He hasn't had that busy a spring so we said we'd just get him started over fences.

"It's a competitive race so we'll have to see how we go.

"I think two and a half miles will be fine for him. He won a Grade Three over two miles, but I think further will suit."

Many of the top stables in Ireland are represented in a 17-runner field, headed by champion trainer Willie Mullins, who saddles Felix Yonger.

The seven-year-old was runner-up to Simonsig in the Neptune Investment Management Novices' Hurdle at last year's Cheltenham Festival but has not run for more than 12 months.

The Dessie Hughes-trained White Star Line has had plenty of experience over fences and was third to Golden Chieftain in the JLT Speciailty Handicap Chase at Cheltenham in March.

Jessica Harrington saddles Operating, Noel Meade has James Benefit, Tom Taaffe has an interesting runner in Heaney while David Wachman, better known as a Flat trainer, is represented by Pageboy.
