Vroum Vroum Mag proved a different class to her opponents once more as she romped to victory in the Grade Two Irish Stallion Farms EBF Dawn Run Mares Novice Chase at Limerick.
The 4-11 favourite, trained by Willie Mullins, took her unblemished record over fences to four as she won with the minimum of fuss in the hands of Ruby Walsh.
Jumping to the front six out, Vroum Vroum Mag was never out of second gear as she dismissed her rivals in comprehensive fashion.
Our Katie tried to lay down a challenge but she could not match the leader's jumping in the closing stages and faded out of contention.
Vroum Vroum Mag went on to win by eight lengths but the margin over 50-1 outsider Shesaportrait could have been much further.
Walsh said: "She jumped super. It wasn't the plan to be in front going up the back but she was travelling so well.
"I thought Our Katie was the danger but our jumping put her under pressure."
Mullins said: "She was very good. That was sort of the novice mares' Gold Cup in Ireland so we kept her back for that. It's the biggest prize for novice mares.
"She's in the Ryanair Gold Cup in Fairyhouse and we will look at that. We could look at Aintree as well, but I would probably look to keep her at home for this year and go to Fairyhouse or Punchestown. I'm not sure which."
