The Champion Chase is the feature race on day two of the Cheltenham Festival, where the Irish will look to add to an opening day tally of 5 winners.
Trainer Willie Mullins, who has never won the 2 mile showpiece, saddles the favourite 'Chacun Pour Soi.
Mullins also has strong claims elsewhere on the card with 'Monkfish' in the 3 mile novices chase and 'Kilcruit' in the bumper.
The going is good to soft for the first of seven races at 1.20.
Tipperary's Rachael Blackmore will look for more success in that first race, the Ballymore Novices’ Hurdle, where she rides the favourite, Bob Olinger for Waterford trainer Henry De Bromhead.
With a preview of today's action, here's WLR Racing correspondent, Mark Phillips:
Ireland has given The Festival™️ so much 🇮🇪
Arkle 'Himself'
The incomparable Istabraq
Danoli, and *that* deafening roar in '94
All-time great trainers, jockeys and horses
Those incredible fans
Thank you - and Happy St Patrick's Day! 🙂#CheltenhamFestival pic.twitter.com/vUgMyNsynq— CheltenhamRacecourse (@CheltenhamRaces) March 17, 2021
