He'll become the fourth horse since World War 2 to win the festival's biggest race on three occasions.
The Willie Mullins trained Al Boum Photo will bid to join racing legends as he looks to win his third successive Cheltenham Gold Cup today.
Since World War 2, only Cottage Rake, Arkle and Best Mate have won the festival's biggest race on three occasions.
The nine-year-old will be ridden by Paul Townend once again in today's feature race at 5-past-3.
'Al Boum Photo' is one of four Irish horses in the blue riband - the others are the mount of Rachael Blackmore, 'A Plus Tard' - 'Kemboy' and 'Minella Indo'.
Mullins says 'Al Boum Photo' is in good shape.
But he'll have to beat Native River, who will be piloted by Richard Johnson:
There have already been 17 Irish winners at the Festival.
The Triumph Hurdle is the first of seven races going to post at 20-past-1.
