Irish trained horses are the favourites for two of the three Grade One races at Cheltenham today.
'Samcro' is odds on to win the Ballymore Novices' Hurdle, and hand trainer Gordon Elliot his first victory at this year's festival.
The Pat Kelly trained 'Presenting Percy' is heavily backed for the R-S-A Novices' Chase.
Willie Mullins will saddle the two main challengers to favourite 'Altior' in the feature, the Queen Mother Champion Chase.
Ruby Walsh could have ridden 'Min', but has stuck with stable mate 'Douvan' in what will be a first outing since suffering a fractured pelvis in the same race last year.
