Let's Dance gave trainer Willie Mullins and jockey Ruby Walsh a remarkable four-timer on day three of the Cheltenham Festival when taking her winning run to five in the Trull House Stud Mares' Novices' Hurdle.Walsh oozed confidence on the 11-8 favourite as he kept the Rich Ricci-owned five-year-old towards the back of the field for most of the race.Verdana Blue led into the straight from Barra but a big leap took Let's Dance to the front and she galloped on strongly up the hill to score by two and three-quarter lengths from Barra. Dusky Legend was a neck away in third.
